NEW YORK (CBSNewYork) — A mother has been charged in Westchester County with systematically poisoning her 5-year-old son to death. 
 
 Lacey Spears, 26, pleaded not guilty Tuesday to charges of second-degree depraved murder and first-degree manslaughter, CBS 2’s Lou Young reported. Her son, Garnett, who was fitted with a feeding tube because of nourishment issues, died in January of sodium poisoning at Westchester Medical Center, authorities said.

 Authorities believe the mother tortured her son medically for years and might have suffered from Munchausen syndrome by proxy, a psychiatric illness in which a parent sickens a child to gain attention and sympathy. Spears often blogged about Garnett’s deteriorating medical condition. 
 
 The case could be the first invovling Munchausen syndrome by proxy in the Internet age, Young reported. 
 
 Prosecutors on Tuesday said Spears fed her son lethal amounts of salt and that the mother had conducted Internet research about the effects salt would have on the boy. Garnett was brought to Nyack Hospital on Jan. 17 with seizure-like symptoms before being transferred to Westchester Medical Center on Jan. 19 after his sodium levels rose with no medical explanation. At the request of doctors, the state Office of Children and Family Services had already launched an investigation into whether Spears was harming her son before Garnett died Jan. 23, prosecutors said.

 Spears, who had been staying with family in Kentucky, turned herself in to Westchester County police Tuesday after an indictment against her was handed up and police obtained an arrest warrant. 
 
 “She really didn’t show any emotion,” Westchester Police Capt. Christopher Calabrese told Young. “She was kind of stoic when she came here. I think that she knew the grand jury was going on. She anticipated this happening, and she turned herself in with her attorney.” 
 
 A judge denied bail for Spears, who faces a maximum sentence of 25 years to life in prison if convicted. 
 
 The only words she said in court Tuesday were “yes, sir” when the judge asked if she was Lacey Spears. 
 
 She is due back in court July 2. 
 
 Spears’ father, Terry Spears, accompanied her to her arraignment Tuesday, but did not speak to reporters. 
 
 Because Garnett died in Westchester County, police there are handling the case. Spears also had lived in Alabama, Florida and Kentucky before moving to New York. 
 
 “Numerous detectives traveled up and down the East Coast numerous times, conducting multiple interviews, examining multiple documents, following a tremendous amount of leads,” Westchester County Public Safety Commissioner George Longworth told reporters. 
 
 Lacey and Garnett Spears lived the last year of the boy’s short life living at the Fellowship Community, an idyllic communal community in Chestnut Ridge, in Rockland County, where the mother cared for the elderly and farmed, and the boy attended school. 
 
 “What went wrong?” Valarie Plausche, a Fellowship Community resident, told Young last month. “What would make someone sick enough to hurt their child?” 
 
 One resident of the community has said Spears called her asking that she dispose of Garnett’s feeding bag just before he died. 
 
 “How did so many people live around that story and none of us knew?” said Kirsten Young, another resident of the community, said in May.

 Assistant District Attorney Doreen Lloyd presented the government's case, focusing on Spears' time at Nyack Hospital between Jan. 17 and 19 when, Lloyd said, the mother took Garnett into the hospital room's private bathroom and administered the sodium into a tube in the boy's stomach. 
 
 "This mother was intentionally feeding her son salt in toxic levels," Lloyd said.

 Earlier in the day, Spears' head was bowed as she walked into the back door of Westchester County Police headquarters in Hawthorne, escorted by detectives. Her father, Terry, had his arm around her as she solemnly surrendered. After being processed -- and having her mug shot taken -- Spears left the headquarters silently, not answering reporters' questions before getting into the back of a black, unmarked police car and speeding off. 
 
 Acting on a sealed grand jury indictment, law enforcement on Tuesday obtained a warrant to arrest the former Chestnut Ridge resident on a charge of second-degree murder and first-degree manslaughter in the Jan. 23 death of her son, Garnett, at Maria Fareri Children's Hospital in Valhalla, sources said. The murder charge does not accuse her of intentionally killing her son but of acting with depraved indifference toward his life. Spears, 26, who had been staying with her parents in Kentucky, had returned to Westchester and was accompanied by her attorney, David Sachs.

 The grand jury's vote concluded a two-week presentation from prosecutors, who based their case on months of investigation in New York, Florida and Alabama -- where Spears and her son lived -- and Tennessee, where they visited Vanderbilt University Hospital. 
 
 Capt. Christopher Calabrese, commander of the Westchester County Police Detective Division, said the investigation involved hundreds of interviews and the analysis of tens of thousands of pages of medical records by Westchester and Ramapo detectives and the Westchester County District Attorney's office.

 "This is a very sad day for everyone, but it is a day for justice," Calabrese said. "Justice for the betrayal of the intimate trust between a mother and child, justice for a mother's continual abuse and death of her innocent child for her own selfish psychological needs and financial gain; justice for Garnett." 
 
 Authorities suspect the single mother, who was a constant presence on social media sharing stories of Garnett's medical crises, may have poisoned the little boy at least twice; once before he experienced seizures that sent him to Nyack Hospital Jan. 17 and again on Jan. 19 at Nyack when his sodium level spiked and he had to be flown to Valhalla. 
 
 As Garnett lay dying in the hospital, a Chestnut Ridge neighbor said Spears called and told her to dispose of a bag Spears used to feed the boy through a tube. Police later recovered the bag which had extremely high levels of sodium. 
 
 The homicide case may be one of the first involving Munchausen by proxy – a psychiatric disorder in which a parent sickens a child to garner sympathy – in the era of social media. 
 
 Spears was living with Garnett in the secluded Fellowship Community when the alleged crime occurred. She faces a maximum of 25 years to life in prison on the murder charge and up to 25 years for manslaughter. 
 
 The reaction in Spears' hometown of Decatur, Ala., was swift. 
 
 Former nurse Ginger Dabbs-Anderson, who first met Spears and Garnett when the boy was six months old, was grateful for the action, but remorseful that it came too late to save Garnett, who friends called "G." 
 
 "I'm happy they got her and I do believe that she's had this problem for years and that he's been suffering at her hands. I really wish we could have prevented this because there were signs. 
 
 "Maybe the hospitals should have caught it, maybe her parents should have caught it, maybe those people closest to her should have caught it. She put all over Facebook how wonderful she was. She had us all snowed, she had us all believing she was wonderful. But obviously not." 
 
 The former nurse was not surprised to learn that officials suspect Spears may suffer a psychological disorder. 
 
 "I don't care if it is a case of Munchausen by Proxy. I think she should get whatever it is anyone else who murders someone gets." 
 
 Shawna Lynch, who knew Spears before Garnett was born and initially defended her, said: "I cried. It broke my heart but thank God they're finally going to get justice for G. I just hope she gets what she deserves. I know G's not coming back, but at least we'll have justice for him." 
 
 At the Fellowship Community in Chestnut Ridge, people were saddened at the mention of Spears and her son. 
 
 "There has to be some way where this isn't true," said one woman who wished not to be named. 
 
 Another Fellowship member said she couldn't reconcile the Spears she knew with the one in court on Tuesday.

 "I don't see her as a murderer," the woman said. "I think (it was) sickness and I think a lot of things happen to us in our lives that are tragic and make us seek this kind of grief or sympathy that she was looking for. We all do it in different ways. I think it was really wrong of course, and I think it was terrible and all I can do is pray for her." 
 
 The charges relate to Garnett's death, but authorities suspect Spears subjected him to past medical abuse, fueled by attention on Facebook, Twitter and blog posts. She presented herself as a doting mother caring for a son who'd been in and out of hospitals his entire life. In a Facebook post in November 2009, she wrote that Garnett was back in the hospital again, his 23rd hospital visit in his first year. 
 
 The investigation began in January, while Garnett was still alive, when doctors at Maria Fareri alerted police that the boy's sodium level had spiked to suspiciously high levels. 
 
 Witnesses told The Journal News they saw a doctor at Maria Fareri confront Spears the night of Jan. 19, shortly after she and her son arrived there on an emergency helicopter flight from Nyack. The doctor told her it was "metabolically impossible" for her son's body to produce such extreme levels, and that "something isn't right." 
 
 At Maria Fareri, Spears continued to sleep in Garnett's room and had unmonitored access to him in the room's attached bathroom, sources said. There was a similar setup at Nyack Hospital. 
 
 The boy was alert and talking on the night of Jan. 20 when friends visited him and Spears in his hospital room. One friend recalled the 5-year-old pleading with her: "Don't leave me." 
 
 It wasn't until the following morning, Jan. 21 — after Garnett's condition worsened and he "coded" — that the medical staff notified the state's child-abuse hotline, prompting police and the district attorney's office to get involved. The boy was taken off life support and declared dead Jan. 23.

 In April, the Westchester Medical Examiner ruled Garnett's death a homicide, and detectives have focused on Lacey Spears from the start. Even before the boy's death, they seized food, her cellphone and computer from her home at the Fellowship Community and confiscated the feeding bag Spears was so concerned about that she contacted her neighbor from the hospital. 
 
 A second Fellowship neighbor reported seeing Spears feed Garnett through his tube Jan. 17, shortly before a seizure sent him to Nyack Hospital. That version of events contradicted Spears' claim to others that she hadn't fed him through the tube for at least a week. 
 
 Both neighbors testified before the grand jury. 
 
 Westchester County police, Ramapo police and the district attorney's office have also secured medical records and video surveillance from Nyack and Maria Fareri, and statements from medical staff and friends who accompanied Spears at both hospitals. 
 
 Investigators have dug into Spears' 14 months at the Fellowship and the time she spent in Alabama and Florida, poring over medical reports and interviewing friends, hospitals and social-service agencies that have fielded calls in the past about Spears' parenting. 
 
 Police have also spoken to members of a parenting group in Spears' former community of Clearwater, Fla., where she'd share tearful stories about raising a sickly son whose father she claimed died in a crash. One member contacted that state's Department of Children and Families in 2011, one of several times Spears was reported to child-welfare authorities. 
 
 None of the reports, however, resulted in action to remove Garnett from her care.

 Spears, who repeatedly sought treatment for Garnett's severe ear infections and purported digestive problems, told friends her son needed to be tube-fed because he'd go days without eating and was a "failure to thrive" case, a diagnosis for children defined by inadequate weight gain. 
 
 But those same friends saw him eat solid foods routinely. To them, Garnett – sporting a gap-toothed smile and long blond hair – appeared happy and healthy. 
 
 During the final hospital stay at Maria Fareri, Spears took to Facebook frequently, pleading for prayers as she posted pictures of her son on life support, noting that the pain in his head was making him scream out loud in pain. 
 
 Then, on Jan. 23, Spears posted a final Facebook declaration: "Garnett the great journeyed onward today at 10:20 a.m." 
 
 Initially flooded with condolences, support for Spears diminished as friends learned about the investigation and stories from her past: that her frequent emergency-room visits raised eyebrows among medical staff; that she misrepresented herself as the mother of a child she babysat; and that she'd lied about Garnett's father. He was not a police officer who died in a crash; he is a garage-door installer still living in Alabama.

 About the series 
 
 Read our five-part series, "Losing Garnett the Great," a Journal News report that follows the life of Lacey Spears from Alabama to Florida to Rockland's Fellowship Community where her well-documented devotion to Garnett ends in his unexplained death. We explore how a woman whose existence centered on her only child became the focus of a police probe into whether her son was poisoned. 
 
 Part 1: Boy's death reveals mom's lies 
 
 A little blond boy beams in dozens of photos on Lacey Spears' MySpace page with captions like "My World My Everything" and "He Completes Me." There's just one problem with this maternal picture: It isn't true. That boy is not her son. 
 
 Part 2: Two fathers; one real, one imagined 
 
 When Chris Hill heard from a friend that Garnett was dying, he reached out to Lacey Spears in the only way he knew how: He sent her a Facebook friend request. It's a strange way for a father to seek news about his son. 
 
 Part 3: Red flags, in and out of the hospital 
 
 Some people in Lacey Spears' life described her as a caring and nurturing mother but others saw darker signs. Were the surgeries, IVs and feeding tube really necessary? Lacey Spears has denied doing anything to harm her son. (Audio: Ex-nurse recalls Lacey as "the biggest liar I ever met.") 
 
 Part 4: Sun and sandcastles 
 
 It was a brief idyll for a happy child. Lacey Spears and son Garnett move to Florida, but the happier times didn't last. Just before Superstorm Sandy, mother and son moved north to Chestnut Ridge and the Sunbridge Institute, known as the Fellowship. 
 
 Part 5: 'Garnett the Great journeyed onward' 
 
 Lacey Spears and her son Garnett settle in to life at the Fellowship, where Lacey spoke frequently about her sickly son's medical history. Garnett seemed like a normal, healthy boy to many in the Chestnut Ridge enclave. In late January, Garnett was transported from Nyack Hospital to Westchester Medical Center. He died Jan. 23. Westchester County Police subsequently launched an investigation.

– After a months-long investigation, an Alabama mom has been charged with murder: Prosecutors in Westchester County, NY, say Lacey Spears poisoned her 5-year-old son through a feeding tube, likely in an effort to gain sympathy on social media. She "was intentionally feeding her son salt in toxic levels," said a district attorney in court yesterday, where Spears pleaded not guilty. Her charges include second-degree murder and first-degree manslaughter; prosecutors aren't arguing that she meant to kill her son Garnett, but they say she behaved without regard for his life, the Journal News reports. There was no medical explanation when his sodium levels soared, and prosecutors say Spears had done online research into how salt affects one's health, CBS 2 reports. The case may be among the first to grapple with the psychiatric disorder Munchausen by proxy in the Internet age: Spears posted updates about her son's frequent illnesses on Facebook. She told friends he needed to be fed through a tube, but they regularly saw him eat solid foods. Police believe Spears may have poisoned him more than once, and the investigation began even before he died on Jan. 23. When he did, she initially got sympathy, the Journal News notes. But some who know her now tell the paper they're not surprised at the charges. "I really wish we could have prevented this because there were signs," says one. "She put all over Facebook how wonderful she was. She had us all snowed." The murder charge carries a sentence of 25 years to life. Click for more on the lies Spears reportedly told.
