 Chicago's most recent spasm of violence touched all corners of the city. 
 
 On Wednesday alone, eight people were shot to death in homicides. A ninth victim — an 11-year-old boy — died of an apparent accidental shooting. 
 
 That marked the most homicides in a single day in Chicago in more than a decade, according to a Tribune analysis of department data. The worst day previously was July 5, 2003, when Chicago saw 10 homicides, the analysis found. 
 
 The spate of violence comes in the waning days of summer as hot and humid weather sent city residents outdoors before Chicago Public Schools classes begin next week. The latest violence has added to a year that already has seen homicides and shootings rise in Chicago and in many big cities across the country. 
 
 Robert Tracy, the department's chief of crime control strategies, said it was unusual for that many homicides to take place in so many different police districts. 
 
 "If you look at the numbers … these shootings took place in different parts of the city," he said. "None of the shootings were connected. They were in eight different districts." 
 
 "It's unfortunate to have this many murders in one day," Tracy said. "Is this the worst it has been? No. We've got to put it into perspective." 
 
 A department spokesman, picking up on a favorite theme of Superintendent Garry McCarthy, blamed the violence on the proliferation of guns. 
 
 "The fact that we lost lives last night is devastating and underscores why the Chicago Police Department is adamant that the city holds gun offenders accountable," said Anthony Guglielmi, director of communications. 
 
 By early Thursday, the toll had risen to 12 killed in homicides over the previous 36-hour span. That would be high even for a weekend, when gun violence normally spikes. The burst of violence began Tuesday afternoon when a teen was killed in Riis Park in the Belmont Central neighborhood and continued until early Thursday with the fatal shooting of a 39-year-old man in Bronzeville. Another 21 people were wounded in shootings during that span.

 So far this year, homicides in Chicago have risen about 20 percent, to 294 through Aug. 23, up from 244 as of that date a year earlier, according to department statistics. Shooting incidents have spiked for a second consecutive year, up 18 percent through Aug. 23 to 1,535, up from 1,300 a year earlier, the department said. 
 
 Homicides have also jumped in many major cities, including Milwaukee and St. Louis in the Midwest. 
 
 Across the country, an average of 31 people are killed every day by gun violence — not including suicide — and 198 are shot and survive, according to the Brady Campaign to Prevent Gun Violence, which advocates for stricter background checks for gun buyers. 
 
 Not included in Wednesday's homicide tally in Chicago was Antwone Price, the 11-year-old who died after he was accidentally shot by a relative who was playing with a gun inside their home in the Park Manor neighborhood. The Police Department, which doesn't classify accidental shootings as homicides, said no charges had been filed against the relative as of Thursday afternoon. 
 
 This was not the first time the family has experienced gun violence. Antwone's father was fatally shot two years ago in the Englewood neighborhood--and his family told the Tribune at that time that his father's father was killed in 2000. 
 
 "He was just a good kid," said Michele Watson, Antwone's grandmother, outside Comer Children's Hospital, where the boy was rushed. "He loved life." 
 
 Family members said the boy was active in his church and dreamed of becoming a funeral director. He even helped make arrangements for his aunt last year after her death. 
 
 "He wasn't your average 11-year-old," said Barbara Sanders, also his grandmother. "He was like a 30-year-old in an 11-year-old body." 
 
 His grandparents said Antwone himself organized his recent transfer to Comer College Prep Middle School, where he started sixth grade about a week ago. 
 
 "He said the previous school wasn't challenging enough for him," Watson said. 
 
 She fondly remembered how Antwone brought fresh flowers and chocolate-covered strawberries for Watson, his mother and his aunt to celebrate Mother's Day.

 pnickeas@tribpub.com ||||| Chicago Tribune reporter Adam Sege recaps the night's crime, including a police involved shooting that left a 15-year-old boy dead. (Posted Monday, June 17, 2013) 
 
 As she headed out the door Sunday morning, Adrianne Wilberton put on a brave face. It was time to tell her son the news, and she didn't want him hearing it from anyone else. 
 
 But her composure unraveled as she walked toward the car, a barrage of neighbors hugging her on the way out of her apartment. By the time she reached the front lawn, the mother of six was in tears. 
 
 "Our son is dead! Oh Jesus!" the 57-year-old screamed, referring to Cortez, one of her three sons, who was killed earlier that morning on Chicago's West Side. "Oh my God! Oh my God! We were just talking." 
 
 At least 34 people were shot — nine of them fatally — Saturday afternoon through Father's Day Sunday, stretching from 94th Street and Loomis Avenue on the South Side up to about North Avenue and North Pulaski Road on the Northwest Side, according to authorities. The youngest person killed during one of the bloodiest weekends in Chicago this year, 15-year-old Michael Westley, was fatally shot by a police officer Sunday night. 
 
 Shootings from Friday afternoon into Saturday left another 13 people shot, 1 fatally. The combined tally resulted in 47 people shot, and eight killed this weekend. Last year at about the same time, there were 53 people shot, nine fatally in one weekend. 
 
 The rash of violent crime came as Chicago has seen a large dip in overall homicide and shooting numbers so far this year. 
 
 When asked whether this weekend's shooting numbers cast doubt on the department's crime-fighting strategies, Chicago police spokesman Adam Collins insisted they are working, noting the city has so far in 2013 posted its lowest homicide totals in years. 
 
 Collins also reiterated a position that police Superintendent Garry McCarthy has expressed publicly throughout the year when discussing the department's crime-fighting efforts. "There's going to be good days, and there's going to be bad days, which is why we've been calling this progress, not victory," said Collins, who pointed out drops in overall crime. 
 
 Across the city, reminders of the bloody weekend literally stained some of Chicago's streets. In the city's Little Village neighborhood, 15 lit memorial candles stood in blood where Ricardo Herrera, 21, was fatally wounded and two others shot on the 2500 block of South Ridgeway Avenue. 
 
 About five miles away, a long trail of blood remained splattered in a Northwest Side alley — and on the bumper of a nearby car — where 16-year-old Kevin Rivera tried to run from a gunman on a bicycle, authorities told the Tribune. 
 
 Rivera's family was planning to move in two weeks from their sometimes violent section of the West Humboldt Park neighborhood and a social worker was enrolling the teenager in the city's summer jobs program. 
 
 But late Saturday night, someone shot Rivera in the 4100 block of West North Avenue, police said. He attempted to run but collapsed a few feet away. The boy, who lived a few blocks away from the scene, was pronounced dead about 1:35 a.m. Sunday at Advocate Illinois Masonic Medical Center, authorities said. 
 
 Grief-stricken and exhausted, Kevin Rivera's family said little about Rivera or his death. "I can't believe it," said Rivera's mother, Maria Figueroa. 
 
 One of six siblings, Rivera could be polite and soft-spoken at home, even as he became increasingly embroiled in neighborhood gang conflicts and faced juvenile court charges. Last year, he was shot in the leg, and he was briefly detained in the Cook County Juvenile Temporary Detention Center and placed on juvenile court probation for carrying an unloaded gun in the neighborhood, according to interviews with relatives. 
 
 His younger sister Yajaira Rivera last year was profiled in a Tribune investigation about elementary students who missed months of school each year. Rivera also missed weeks of school each year at Nobel Elementary School, where he earned an A in 7th grade art class but failed basic courses and had run-ins with teachers and staff, school records and interviews show. 
 
 In a brief Tribune interview last year, Rivera said he had tried to register at Orr Academy High School, but left after a couple of days because he didn't feel safe there. "There is a lot of tension," he said. 
 
 Social worker Emily Runyan, who lived in the neighborhood and befriended Rivera's family, was recently working to enroll Rivera in the city's One Summer Chicago teen jobs program. 
 
 "I don't want to memorialize him because he made some bad choices, but Kevin was a kind, quiet and sensitive kid," Runyan said. "I truly believe he wanted more for his life, but was a victim of many things." 
 
 One of the men killed — 24-year-old Antwon Johnson — was shot by police early Sunday in the Lawndale neighborhood after he raised a 9-millimeter handgun in their direction after bailing from a moving car and falling, police said. 
 
 His mother disputed that account. "It's not true," said Stacy Liberty. "How could someone have a gun and point it to you if they're already on the ground?" 
 
 Liberty said the car had been lurching down the block because the people in the car were trying to identify an address. The presence of a police car behind them must have made Johnson nervous, his mother said. 
 
 Johnson had been convicted three times for drug related charges stemming back to 2006, according to court records. He suffered three gunshot wounds almost two years ago, she said. 
 
 But the father of two five-year-old sons was trying to get his life back on track, she said. 
 
 "He hasn’t been in trouble in a while," said Liberty, who rushed to the scene and recalled seeing her son's lifeless body in the alley. "He was trying to get his stuff together. Black men on the street today, it's tough for them to get a job because the first thing (employers) look at is their record." 
 
 Another victim included 40-year-old Todd Wood, who authorities said was killed after a gunman opened fire at a club in the city's Grand Crossing neighborhood. Three others were wounded in that attack, police said. 
 
 Several hours after the club shooting, Cortez Wilberton, 31, was added to the homicide list. Wilberton had seen plenty of his friends shot over the year, but hit a turning point a few years back when his best friend was killed, his sister said. A former gang member, Wilberton had a lengthy criminal record that included at least 30 arrests, according to court records. 
 
 "That's when he said, 'That's enough of this here … I don't want to be bothered by all this nonsense,' " said his sister, Tanya Wilberton, 37. 
 
 So he left the gang and started focusing all of his energy on his three children, one of whom was born earlier this month, she said. He liked to take his children — two girls and a boy — to the park and watch the older ones ride their bikes, his mother and sister said. 
 
 Sometime early last year, Wilberton was shot in the stomach during a robbery and had to leave his a job as a security guard at a local store, his sister said. 
 
 Still recovering from reconstructive surgery, he mostly stayed indoors at night but was gunned down at 1:35 a.m. on the 200 block of South Keeler Avenue in the Austin neighborhood. A 31-year-old woman also suffered a graze wound to the face in that incident, police said. 
 
 Around the time Wilberton's family gathered Sunday morning to mourn, Karen Sumner received a call at work telling her to hurry home because police officers wanted to talk about her 19-year-old son. 
 
 "I hope my son's not dead," Sumner remembers saying. "Please, I hope my son's not dead." 
 
 But when she arrived at the family's West Chatham home, officers delivered the news she feared most. 
 
 Her son, Jamal Jones, was shot at about 1:15 a.m. Sunday while riding his bike home from a family member's house through the 7400 block of South Parnell Avenue in the Englewood neighborhood, police and relatives said. He died about an hour later. 
 
 Jones was a friendly, motivated young man who steered away from trouble and was always eager to work, according to relatives. He'd sometimes peddle bottled water to passing cars on 79th Street when he couldn't find construction work, his mother said. 
 
 Jones' uncle, Travis Sumner, said his nephew was a reliable member of his roofing crew. Jones worked as the ground man, picking up trash and making sure supplies got up to the laborers on the roof. 
 
 "He worked hard," the uncle said. "He stayed busy all the time." 
 
 On Sunday afternoon, family members returned to the shooting scene. They found the bike Jones had been riding and needles left over from the paramedics. 
 
 As she recalled getting ready for her job at Jewel-Osco on Sunday morning, Karen Sumner said it was odd that her son wasn't there to say goodbye when she left the house at 3:30 a.m. At that time, she still hadn't heard the news. 
 
 "He would always greet me at the door and kiss me and say 'I love you,' " Karen Sumner said on Sunday. "This morning, he didn’t greet me." 
 
 By Monday morning the toll had grown by another fatality when Alexander Lagunas, 18, was pronounced dead at 10:08 a.m. at Mount Sinai, according to the Cook County medical examiner's office. 
 
 Lagunas, of the 8100 block of South Scottsdale was shot on the 4000 block of West 31st Street at 12:31 a.m. Sunday morning, according to police.

– Wednesday marked the deadliest day for Chicago in more than a decade with nine people killed by gunshots in eight different districts across the city. Such gun violence hasn't been seen in Chicago since July 5, 2003, when 10 homicides occurred, reports the Chicago Tribune. Police say the various shootings were unconnected (though two 30-something men did die in one shooting). Among the dead are two 19-year-olds; a woman in her 20s; a 25-year-old man shot in the head, chest, and groin; and a 60-year-old man, NBC Chicago reports. "It's unfortunate to have this many murders in one day," says an officer. "Is this the worst it has been? No. We've got to put it into perspective." Police say one of the nine gunshot deaths wasn't a homicide but was accidental: 11-year-old Antwone J. Price was shot by a family member who was fooling around with a gun. His father and grandfather previously died in shootings, his family says. Over 36 hours from Tuesday afternoon to early Thursday, the death toll reached 12. Homicides have now spiked 20% in Chicago over last year, with 294 as of Aug. 23, compared to 244 by that date in 2014.
