(CNN) Cynthia Tisdale spent the last years of her life working two jobs to help pay for the medical expenses of her husband, who suffers from a life-threatening lung disease. 
 
 Now it appears the death of the beloved substitute teacher in the Santa Fe High School shooting may lead to him getting the medical treatment that could save his life. 
 
 Tisdale's husband, William, suffers from idiopathic pulmonary fibrosis , a life-threatening disease that causes scarring in the lungs. It leads to breathing difficulties and a shortage of oxygen in the brain and other organs. And sufferers can only expect a life expectancy of up to five years after diagnosis. 
 
 His family set up a GoFundMe page in late March to raise the money for a stem cell treatment. Funds came in slowly at first but soared over the weekend as people learned more about Tisdale and her devotion to her husband. 
 
 By Monday morning, the campaign had already exceeded its $30,000 goal -- enough to pay for the stem cell treatment and possibly (with a second opinion) get a lung transplant. 
 
 "We are still in such disbelief that anything good can come out of such a horrific event," the family said. "My mom always made good come out of bad situations though and this is no different for her." 
 
 Giving her husband a second chance at life 
 
 Tisdale was considered something of a saint by her family and friends in Pharr, Texas. The mother of four children was described as kind and generous by those who went to church with her at Anchor Bible Baptist Church in Pharr. 
 
 But her greatest act of kindness and love was toward her husband, William. 
 
 She worked as a substitute teacher during the day and as server at a local restaurant at night to help pay for his medical expenses, her brother-in-law John told The Monitor newspaper. 
 
 "Since my brother has been very ill the last couple of years, she was a very excellent caregiver and she worked two jobs for extra income to help," the brother-in-law said. "She worked at the school and a second job as a server at night at an Italian restaurant chain." 
 
 Tisdale's husband was diagnosed with the disease back in December and was told he had at most about a year and half to live. His doctor told him he wasn't a good candidate for a lung transplant, Tisdale's family said, so lung stem cell treatment may be his only shot at prolonging his life. 
 
 And with the money that's coming in to the GoFundMe page , that's now a possibility. 
 
 "We don't know how to put it all into words but thank you doesn't give it enough justification. We (reached) the goal for funeral costs, bills, and possible lung transplant with second (doctor) that we never thought was an option," the family wrote. 
 
 Her son, a detective, ID'd her body 
 
 Tisdale was one of 10 people killed when a gunman, armed with a shotgun and a .38-caliber handgun, opened fire at Santa Fe High School soon after classes started on Friday morning. 
 
 It was Tisdale's own son, a detective who responded to the shooting scene, who had to identify her body and notify other family members of her death, The Monitor reported. 
 
 The shooting suspect, 17-year-old Dimitrios Pagourtzis, was arrested and charged with capital murder and aggravated assault on a public servant. 
 
 Her family said William Tisdale is devastated by the loss of his wife yet cognizant of the fact that even in death, she is still helping him. 
 
 "It was hard for him to fight before and now losing my mom has made it unbearable," the family wrote on the GoFundMe page, "but every little notification on his phone gives him a chance at something." ||||| An off-duty police officer who responded to the Santa Fe High School shooting discovered his mother was one of the victims. 
 
 Cynthia and William Tisdale 
 
 Cynthia Tisdale was one of two substitute teachers killed by a gunman while teaching first period art class Friday. Eight students also died. 
 
 League City Police Department Detective Recie Tisdale, Cynthia’s oldest son, said a friend called him about the shooting so he rushed to the scene. 
 
 Thankfully, his daughter has late arrival on Fridays so she was still at home.

 When Tisdale arrived, he was told two teachers had been killed. Soon after, he learned his mother was one of them. 
 
 He had to identify his mother's body and break the news to his father and the rest of the family. 
 
 “It was very hard to go from assisting others to being horribly affected by this tragic event,” Recie said in a statement Monday. “There are no words to explain how saddened my family is for everyone involved. Our prayers and thoughts are with everyone affected.”

 Recie said his parents had been married for 46 years and had three children and 11 grandchildren. 
 
 His father, William Tisdale, has a life-threatening illness so his mother spent much of her time caring for him. 
 
 “Since my brother has been very ill the last couple of years, she was a very excellent caregiver and she worked two jobs for extra income to help,” Brother-in-law John Tisdale told The Monitor newspaper. “She worked at the school and a second job as a server at night at an Italian restaurant chain." 
 
 After her death, donations on a GoFundMe.com page set up by the family quickly soared. 
 
 Recie Tisdale wrote a touching and poignant letter to his mother: 
 
 "To all on behalf of William Recie Tisdale, Sr. and Cynthia Tisdale, 
 
 "My name is Recie Tisdale, Jr. and I am the eldest son of Cynthia. I am writing this to honor the life and memory of my mother. Where do I start? My mom would have been 64 next week. She married my father at 17 years of age and they have been married 46 years. I have two siblings Joseph and Autumn Tisdale. She also has a step-daughter, Shannon McCoy and 11 grandchildren. Cynthia made a point to stay at home most of our childhood to raise us while my father worked and ministered at a Baptist church. As we got older, my mother decided to enter the job market.She worked different jobs throughout her life until my father started his own business. A few years ago, my father became ill and has recently required full-time assistance so my mother also filled that role. She has cared for my father every day of their lives not to mention keeping up with a bunch of grandchildren. During the past year she even found time to attend physical therapy most weeks with my eldest daughter following a terrible accident. Her support, love and encouragement are part of the reason my daughter is walking again. 
 
 "This year Cynthia enjoyed helping others so much she decided to go to work as a substitute teacher at Santa Fe High School working with special needs kids. 
 
 "My youngest attends high school there and my wife Jennifer also works for Santa Fe ISD. As a result, the community of Santa Fe is a large part of our lives. 
 
 "(Cynthia) worked there not out of necessity but for the love of teaching and helping others. To know my mom was to know a person who lived to help those in need. We loved our mother very much. Grammie you will be missed. 
 
 "The day of this senseless event my mother left for work in the morning. My family and I live 10 minutes from the school. I was off-duty on that Friday. My friend and co-worker notified me of a school shooting because my child attends school there. 
 
 "Because it was Friday, my daughter had late arrival and thankfully was still home. She often met with her grandmother in the morning. Being a police detective, I immediately gathered my gear and responded to the school to help those in need. Upon my arrival I was met by several of my League City Police brethren. We all assisted the best that we could along with all the other brave men and women. 
 
 "The shooting had just been neutralized prior to my arrival. Once the scene was somewhat secure, I was contacted by my father who could not reach my mom. I knew that two female teachers had been killed along with several students. Not long thereafter I determined that one of the teachers was probably my mother. It was very hard to go from assisting others to being horribly affected by this tragic event. There are no words to explain how saddened my entire family is for everyone involved. Our prayers and thoughts are with everyone affected." 
 
 Cynthia Tisdale's funeral is Friday, the day she would have turned 64. 
 
 The Santa Fe tragedy also hit home for Galveston County Sheriff Henry Trochesset. 
 
 His granddaughter was in the school, three doors down from where the shooting started. She was able to escape but her best friend was killed. 
 
 "This tragedy in this community touches home more than you'd imagine," Trochesset said. 
 
 © 2018 KHOU ||||| KNOXVILLE (WATE) – A freshman football player at Maryville College has been charged in a murder investigation of a high school girl. 
 
 William Riley Gaul, 18, was charged with first degree murder, according to the Knox County Sheriff’s Office. Martha Dooley, a spokesperson for the sheriff’s office said the victim’s name was Emma Walker, 16. The teen was found dead in her home with a gunshot wound. 
 
 The sheriff’s office said at a press conference on November 30 that Gaul fired into her home while she slept, knowing where she was in the house, and then jumped the fence and fired again. Investigators say the two had an ongoing tumultuous relationship. 
 
 Students gathered at Central High School Tuesday night to remember Walker. 
 
 “On the pep rally day, she let me come and cheer with her and dance with her,” said friend Ashley Beets. 
 
 Beets brought balloons and flowers to the memorial next to Central High School’s football field. 
 
 “She’s my best friend,” said Beets. 
 
 Teachers at the high school are heartbroken over this loss. 
 
 “She was a leader both inside and outside the classroom. Always had a smile on her face, just a beautiful soul and she’s going to be missed by a lot of people,” said Chris Hammond, a health science teacher at CHS. 
 
 Hammond says Walker had told him she wanted to be a neonatal nurse. 
 
 “She had the kind of disposition and the heart that it would take to do that job.” 
 
 While it will take time to heal, many are remembering the mark she’s left behind at the school. 
 
 “Her heart for other people, her love for other people, for kids, for classmates, for school, it’s just overwhelming,” said Hammond. 
 
 Principal Michael Reynolds stated: 
 
 “This has been a very difficult time for the family, students and staff. Our student was a wonderful young lady, a cheerleader and honor student with a promising future, whose life has been cut too short, too soon. At this time, our hearts and thoughts and prayers are with the family as they go through this grieving process. We thank everyone in our community for their tremendous support.” 
 
 A crowdfunding page was set up to help Walker’s family. The donations will go toward a fund set up for Walker’s parents Mark and Jill at Regions Bank. Also, deposits can be made at any branch location. 
 
 To Donate: Emma Walker Memorial Fund 
 
 On the crowdfunding page, family friend Aneisa McDonald wrote: 
 
 “Her fun, kind, sweet spirit was contagious. Emma was a beauty inside and out. Our community was blessed to know her. Her dream was to become a nurse.” 
 
 Investigators believe the suspect fired into the teen’s bedroom from outside the home while she was sleeping. Gaul was arrested at the Woodlands Apartments on Cherokee Trail and is being held on a $750,000 bond at the Knox County Jail. 
 
 Investigators believe Gaul was trying to destroy evidence related to the investigation. 
 
 Gaul, who is graduated from Central High School, played as a wide receiver for Maryville College. On Tuesday, he posted a series of tweets about the victim. 
 
 Maryville College released a statement, saying: “Maryville College is cooperating fully with the Knox County Sheriff’s Department in this investigation. Our thoughts and prayers are with the victim’s family and friends and other individuals affected by this tragedy.” 
 
 Ashlee Alleman, Gaul’s mother, did not want to go on camera but spoke to WATE 6 On Your Side on the phone. She said, “Riley did not do this. He would not hurt here because he loved Emma dearly. He is not a monster.” 
 
 Alleman said Walker and Gaul were still really close. She said Gaul helped Walker with a paper for school on Sunday. 
 
 I love you Emma, I can't be around any of that yet, it's too soon. I know you know I'm dying to be there but understand I can't. I love you. — Riley (@rileygaul) November 22, 2016 
 
 That's my beautiful Emma. Rest easy now sweetheart. 1 Corinthians 13:8. Be sure to remind God about our verse.I love you.Forever and always. pic.twitter.com/gD2stHbY3z — Riley (@rileygaul) November 21, 2016 ||||| SAN BERNARDINO >> As community members mourned Tuesday for the victims of the shooting at North Park Elementary School the day before, details began to emerge. 
 
 The 9-year-old boy who was wounded Monday is awake and expected to survive, San Bernardino Police Chief Jarrod Burguan said Tuesday at a news conference at police headquarters in downtown San Bernardino. 
 
 “All things considered, he’s in relatively good spirits,” Burguan said. 
 
 Added San Bernardino City Unified Superintendent Dale Marsden, “He’s up and watching cartoons.” 
 
 Monday morning, Cedric Anderson, 53, of Riverside, went to the elementary school where his wife, Karen Elaine Smith, 53, a 10-year veteran of the school district, was working. Saying he was just there to drop something off, he went to her classroom where Smith was, along with two classroom aides and 15 special needs students. 
 
 Anderson took just a few steps into Classroom B1, and, without saying a word, pulled out a Smith & Wesson .357 Magnum revolver and fired 10 shots, reloading midway through, authorities said. Smith was killed immediately. Two boys, Jonathan Martinez, 8, and a 9-year-old fellow student, who has not been identified, were struck near her. 
 
 Jonathan Martinez 
 
 Jonathan was born with Williams syndrome, a genetic condition that affects about 1 in 10,000 people worldwide, including an estimated 20,000 to 30,000 people in the United States. The syndrome causes cardiovascular disease, developmental delays and learning delays, according to the Williams Syndrome Association. 
 
 “Children with Williams syndrome tend to be social, friendly and endearing,” Marsden said. 
 
 A GoFundMe account is raising money to pay for the funeral and other expenses for Jonathan’s family. 
 
 By Tuesday evening, it had raised more than $65,000. 
 
 “We honestly can’t thank everyone enough,” Jonathan’s cousin, Brianna Lopez, wrote. “We appreciate everyone’s sweet words, and we are very speechless. Thank you (for) coming together. We will keep everyone updated on any further news. My family truly truly appreciates everything from the bottom of our hearts.” 
 
 Kate Cichy, who handles regional communications for GoFundMe, said a verification team is working with Lopez to ensure that the funds go to Jonathan’s parents. 
 
 Cedric Anderson 
 
 After shooting Smith and the two boys, Anderson killed himself. 
 
 Anderson had been arrested twice in Torrance, police records show. 
 
 He and Smith married on Jan. 28, but had separated. Neither of the cases in Torrance involved Smith. 
 
 By mid-March, Smith had moved out of their Riverside home amidst allegations of infidelity and was living with family, including her adult children. (All of her children have been checked on and are fine, according to police.) 
 
 “It appears that he had been attempting to contact her and get her to move back home,” Burguan said. 
 
 According to Smith family members interviewed by police, Anderson had made threats — although not that he intended to shoot her — but she didn’t view them as serious and just thought he was looking for attention. Smith apparently did not tell anyone but her closest family members about his odd behavior and the problems she and Anderson were experiencing. 
 
 “She effectively kept her private life private,” Burguan said. 
 
 During their search of the Riverside home on Monday, investigators found a note from Anderson about needing closure and feeling disrespected. But nothing about it suggested it was necessarily a suicide note. 
 
 “If found outside of the context of this case, I’m not sure anyone would be terribly alarmed,” Burguan said. 
 
 Neighbors at the Mount Wasatch Drive house said they saw police detain a man whom Burguan identified Tuesday as Anderson’s brother. He was interviewed but not arrested, Burguan said. 
 
 A computer and phone taken from the residence will be examined, authorities said. 
 
 Unlike the phone of Dec. 2, 2015, shooter Syed Rizwan Farook, which was hacked only when the FBI hired a company to override the encryption, police do not expect to have difficulty obtaining information from Anderson’s and Smith’s phones, Burguan said. 
 
 Police are now looking at a personal computer and cellphones obtained during their investigation. 
 
 Surveillance video at North Park shows Anderson attempted to get in through locked external doors before going through the main office, as school security requires. There, since staff knew him, they sent him to Classroom B1 and Smith. 
 
 “There was no indication to anyone (on) staff that he was a threat,” Marsden said. “The staff knew this newlywed couple but had no information about the crisis they were in.” 
 
 Anderson was arrested four times between 1982 and 2013, according to Burguan, including for nongun weapons charges, domestic violence and theft, but never convicted. It is not yet known if the domestic violence charge involved Smith. An unemployed maintenance worker, Anderson was reportedly trying to start his own business. 
 
 The Smith & Wesson revolver Anderson used Monday was purchased in Michigan in 1979 by someone other than him. It’s not yet clear how Anderson got the gun, Burguan said. 
 
 Not uncommon for spouses to visit 
 
 Marsden said all district policies were complied with when Anderson was let onto campus. 
 
 “It’s not uncommon for spouses to visit. There does not appear to be a breakdown of security,” Burguan said. “There will be a full and complete review, but it appears that things worked as they were supposed to, beyond this being a regrettable tragedy.” 
 
 North Park Elementary will be closed until Monday. All other district schools will remain open. 
 
 The district will do a complete review of its school visitation policies and procedures, according to a news release sent Tuesday afternoon. 
 
 Domestic violence 
 
 Twitter posts using the hashtag #KarenSmith began to pop up accompanied by messages about domestic violence. 
 
 “A woman is shot and killed by her partner every 16 hours. Domestic abusers should not have access to firearms. #KarenSmith,” read a post from user Erin Aura. 
 
 Another man, identifying himself as Renee Graham, pointed out that if Anderson had killed Smith in their home instead of a classroom, the attack wouldn’t be national news. He then urged people to “(s)top ignoring domestic violence.” 
 
 Because of the attack, Assemblywoman Eloise Gómez Reyes and Option House Inc. will hold a news conference today at Option House in San Bernardino to discuss domestic violence and the importance of speaking out when it occurs. 
 
 “It’s imperative that we do everything possible to call out domestic violence when it happens and to be there for the victims and connect them with services so they can begin the healing process,” said Reyes, a member of the Assembly Select Committee on Domestic Violence. 
 
 The gun-control group Everytown for Gun Safety released a study Tuesday showing that between 2009 and 2016 in the U.S. there were 156 mass shootings, resulting in 848 fatalities. The group defines a mass shooting as an event in which at least four people, not including the shooter, are killed by a gun. 
 
 Of those shootings, 54 percent involved domestic or family violence, according to Everytown. 
 
 Staff writers Beatriz Valenzuela, Brian Rokos and Larry Altman contributed to this report.
– One of the victims in the Santa Fe school shooting was Cynthia Tisdale, a 63-year-old substitute teacher who WFMY reports was killed Friday while teaching a first-period art class. But while family and friends mourn her death in this "terrible act of violence," BuzzFeed notes a glimmer of hope amid the tragedy. Tisdale's job at Santa Fe High School was just one of two she held down to help her family get by, as her husband, William Recie Tisdale, is homebound with an incurable lung disease called idiopathic pulmonary fibrosis. In December, William Tisdale was given just 12 to 18 months to live and was denied a lung transplant, so his family set up a GoFundMe page in March to help raise funds for a stem cell treatment, with an original goal of $30,000. Funds slowly trickled in—but Cynthia Tisdale's death changed the pace. After the story of her death and her husband's plight started to circulate, money started pouring in; the page has since raised more than $100,000, which the family says will be used for funeral costs, the stem cell treatment, and even maybe a lung transplant from a different doctor, an option the family is now able to consider. CNN notes William Tisdale is "devastated" at his wife's murder, but the kindness of strangers and their financial support have raised his spirits. "We are still in such disbelief that anything good can come out of such a horrific event," one of Cynthia Tisdale's children writes on the GoFundMe page. "My mom always made good come out of bad situations though and this is no different for her." Cynthia Tisdale's brother wrote on Facebook, via BuzzFeed: "I am sure Cynthia is rejoicing in heaven knowing her death may save her husband of 47 years."
