The slaying of Tyshawn Lee was so heinous it stood out even among the hardened criminals at Cook County Jail. 
 
 It was there — on tiers where accused armed robbers, killers and gang members await trial — that a 22-year-old gang member started bragging about how he had lured the innocent 9-year-old into an alley with a promise of treats and then looked him in the face before fatally shooting him, law enforcement sources told the Tribune. He'd written it all down in a rap song and had contemplated even more grisly plans such as torturing the child, according to prosecutors. 
 
 The chilling details emerged Tuesday after authorities charged Dwright Boone-Doty, a reputed gunman for the Bang Bang Gang/Terror Dome faction of the Black P Stones, with killing Tyshawn because of his father's alleged gang ties. 
 
 It marked the second alleged gang member to be charged. A third remains at large. 
 
 A crucial break in the investigation came with the cooperation of an inmate who secretly recorded Boone-Doty's conversations, according to the sources. Chicago police detectives then worked round-the-clock monitoring the chatter and verifying details of what they were hearing. 
 
 The targeted slaying in early November of a child as part of an ongoing gang war horrified Chicago and the nation because of its brutal nature. But Tyshawn was not the only innocent victim caught in the crossfire of the long-running feud between the Black P Stones faction and Killa Ward, an offshoot of the Gangster Disciples. Weeks earlier, Boone-Doty had gunned down Brianna Jenkins, a 19-year-old woman who aspired to be a nurse, as she sat next to the intended target, a rival gang member whom she had recently met, according to prosecutors and family. 
 
 All told, Chicago police are investigating that the gang war in the Auburn Gresham neighborhood has led to at least 15 shootings, including at least five homicides, since 2011, according to the sources. 
 
 Police said neither the human toll nor length of the violent rivalry were unprecedented for Chicago's gang wars, which are increasingly fueled by block-to-block feuds by smaller factions. That it snared a 9-year-old, however, stunned the most seasoned police officers. 
 
 "In nearly 30 years of policing, I have never witnessed such a hateful act of treachery and savageness towards an innocent child," interim Police Superintendent John Escalante said at a news conference announcing the charges. 
 
 On Tuesday a judge ordered Boone-Doty held without bail for both slayings after his appearance in a packed courtroom with his hands and legs in shackles surrounded by half a dozen sheriff's officials. 
 
 Tyshawn's mother, Karla Lee, left the courtroom during the bond hearing and could be heard wailing in the hallway.

 After serving about two years on a five-year sentence in a drug and gun case, Boone-Doty had been paroled from the Illinois Department of Corrections two months before Jenkins was shot, authorities said. Boone-Doty had at least one prior weapon conviction for which he served time in state prison. 
 
 After the informant told jail officials of his conversations with Boone-Doty, Chicago police detectives obtained a court order for him to wear a wire and record Boone-Doty, the sources said. The recordings captured Boone-Doty implicating himself in both killings, according to the sources. 
 
 In addition, prosecutors said they have physical evidence and GPS data linking him to the killings. 
 
 The feud with Killa Ward escalated significantly Oct. 13 when Tracey Morgan, a reputed Bang Bang Gang/Terror Dome member, was shot and killed while leaving a mandatory parolee meeting with Chicago police on the South Side. Morgan's mother, who was in the car with him, was wounded. 
 
 This breach of unwritten gang protocol — the wounding of a mother — drew a fiery response. Corey Morgan, Tracey's brother, was heard to say that he was targeting "grandmas, mamas, kids and all" for shootings, prosecutors have alleged. 
 
 Morgan, Boone-Doty and a third suspect took to the streets daily to make good on that promise, prosecutors said Tuesday. At one point, Boone-Doty conducted surveillance on Tyshawn's grandmother with plans to kill her in order to draw out rival gang members, prosecutors alleged. 
 
 It was during this time that the trio allegedly saw Tyshawn with his father, an alleged Killa Ward member, according to a law enforcement source. 
 
 On the afternoon of Oct. 18, five days after Tracey Morgan was killed, Boone-Doty was driving near the area of 78th and Honore streets when he spotted a rival gang member sitting in a car, according to prosecutors. Boone-Doty exited his car, walked up to the rival's vehicle and opened fire at the rival and Jenkins, who was sitting beside him, prosecutors said. 
 
 Boone-Doty said he shot Jenkins "because she started screaming," prosecutors said. 
 
 Police have linked a gun recovered from Boone-Doty to Jenkins' killing, prosecutors said. 
 
 The trio's plan for revenge did not end there, the charges alleged. On the afternoon of Nov. 2, they spotted Tyshawn playing basketball in Dawes Park, prosecutors said. 
 
 Boone-Doty lured Tyshawn out of a play lot by asking him if he wanted to go to the store, according to prosecutors. When the boy said he had no money, Boone-Doty said he would buy him whatever he wanted, prosecutors said. 
 
 Tyshawn, a fourth-grader at Joplin Elementary School, was lured to the alley in the 8000 block of South Damen Avenue and shot repeatedly. A basketball that he always carried with him was found nearby. Neighbors heard shots ring out. 
 
 "Nothing but a child. A little kid just 9 years old," Sidney Grandberry, who owns the garage where Tyshawn was found, said Tuesday. "He trusted him and they did that to him. I will never forget that." 
 
 Prosecutors alleged in court that Boone-Doty laughed as he described to the other inmate how he shot Tyshawn in the head. 
 
 "Shorty, he couldn't take it no more," Boone-Doty allegedly said. 
 
 Boone-Doty considered torturing the child by cutting off his fingers and ears, according to prosecutors. He also bragged that he had written a rap song about the slaying, they said. 
 
 "I don't think I have ever been more disgusted and appalled by such inhumanity," Cook County State's Attorney Anita Alvarez said Tuesday at the news conference at police headquarters. "The intentional murder of Tyshawn Lee is the among the worst I have ever seen in my almost 30 years as a prosecutor." ||||| Tyshawn Lee's 'Coward' Executioner Charged in Murder That Devastated City View Full Caption 
 
 AUBURN GRESHAM — The executioner of 9-year-old Tyshawn Lee — the Chicago boy lured away from a park and shot dead to get back at his family during a gang feud — laughed and bragged about killing the boy while in jail on a separate charge, prosecutors said Tuesday. 
 
 First-degree murder charges have been filed against Dwright Boone-Doty, 22, the alleged gunman in the crime that stunned the city and drew national headlines. 
 
 He was also charged this week in the Oct. 18 murder of 19-year-old Brianna Jenkins — a case in which Boone-Doty was gunning for rival gang members and fatally shot Jenkins to "shut her up," prosecutors allege.

 Boone-Doty was held without bail Tuesday after prosecutors described the brutal murder of Tyshawn — and how seemingly proud of himself Boone-Doty was after allegedly committing it. 
 
 “Shorty, he was like he couldn’t take it no more," Boone-Doty reportedly said as he repeatedly laughed and described shooting Tyshawn in the face, according to prosecutors. "Shorty couldn’t take it no more.”

 Tyshawn was hit in his back, forearm and head, and part of his thumb was shot off as if he were raising his hand to block the shots, prosecutors said previously. Boone-Doty was facing Tyshawn when he shot him, something he had wanted to do "because he was so little," according to prosecutors. 
 
 Boone-Doty also had a rap song about the slaying in the works and said he regretted not going back to the park to kill more kids, Assistant State's Attorney George Canellis said during a bond hearing Tuesday. 
 
 "In my nearly 30 years of policing, I have never witnessed such a hateful act of treachery ... and zero regard for human life," Interim Police Supt. John Escalante said Tuesday during a news conference. 
 
 According to Cook County State's Attorney Anita Alvarez, the murder was the result of a gang feud between two factions of the Gangster Disciples. Boone-Doty and his accomplices initially planned to kill Tyshawn's grandmother, she said. But when that didn't pan out, the men focused on Tyshawn because his father was a "ranking gang member." 
 
 "His original plan was to torture this child by kidnapping and cutting off his fingers and his ears," Alvarez said. 
 
 The men allegedly went out with guns daily looking for someone to shoot in retaliation after co-defendant Corey Morgan's brother was killed by gang gunfire. Boone-Doty was "on a killing spree with absolutely no sense of humanity," Alvarez said. 
 
 Police have already charged Morgan, 27, with murder in Tyshawn's shooting. A third suspect, Kevin Williams, is still at large. 
 
 "Last fall, Tyshawn Lee’s horrific murder shocked the collective conscience of our city," Mayor Rahm Emanuel said in a statement. "It was one of the most disturbing examples of the terrible toll that having too many gangs, too many guns and too few values has taken on our communities." 
 
 The boy's Nov. 2 murder shocked the city — and the story became even more stunning when police said it was no accident. Tyshawn was lured from a basketball game at Dawes Park by Boone-Doty, who dribbled the child's basketball for a few minutes and offered to buy the child whatever he wanted from the store before taking him into the alley and shooting him multiple times at close range, Alvarez said. Morgan and Williams allegedly looked on in a nearby SUV. 
 
 TRANSCRIPT: Police Describe Tyshawn Lee's Murder, Criminal Investigation 
 
 The gang feud came to a boil after an Oct. 13 shooting in which Morgan's brother, Tracey Morgan, was killed and his mother was wounded. Morgan was so enraged he threatened to shoot "grandmas, mamas, kids and all" in retaliation. Another man involved in Tyshawn's shooting said "everybody must die," according to prosecutors. 
 
 Though police maintain Tyshawn was killed due his father's gang ties, Pierre Stokes told DNAinfo he gave up gangbanging for his son. Stokes helped in the investigation, but he was initially reluctant, officials said. 
 
 Boone-Doty's brutality was further illustrated when prosecutors described how he killed Jenkins weeks before Tyshawn. On Oct. 18, Brianna Jenkins and Dashari Bowens were in a car in the 7800 block of South Honore Street when Boone-Doty passed by in different vehicle, according to Canellis. 
 
 Boone-Doty didn't see who was in the car, officials said Tuesday, but he saw dreadlocks and thought it might be a rival gang member. Boone-Doty got out and fired multiple shots into the car, killing Jenkins and wounding Bowens. Jenkins was not an intended target. 
 
 Boone-Doty later admitted that Jenkins started screaming when he began shooting, so he shot the woman to "instantly shut her up," prosecutors said. 
 
 When Boone-Doty later learned that Bowens didn't die, Boone-Doty tried to find the shooting victim at Advocate Christ Masonic Medical Center to finish the job — but he wasn't able to get in, prosecutors said. 
 
 Boone-Doty was later was arrested with multiple guns, according to Canellis. One of the weapons was a positive match to the gun that killed Jenkins and wounded Bowens. 
 
 Boone-Doty previously was convicted of drug and gun charges in 2013 and sentenced to five years in prison. He was sentenced to two years in prison for a 2011 drug and gun case. 
 
 As a juvenile, Boone-Doty was convicted of a gun charge in 2010 and sentenced to the Illinois Youth Center in suburban St. Charles. 
 
 Chief of Detectives Eugene Roy said Boone-Doty should not have been free and able to kill, and that that illustrates problems with the criminal justice system. 
 
 Police "will continue to hold gang members accountable time and time again," Roy said. 
 
 Emanuel thanked police in an emailed statement Tuesday. 
 
 "Long after the spotlight faded, the men and women of the Chicago Police Department remained dedicated to finding justice and their determination drove today's result," Rahm said.

 Tyshawn Lee was playing on a swing set in the park like any fourth-grader when a stranger walked up and grabbed his basketball. 
 
 The man dribbled a few times, handed the ball to the 9-year-old and asked if he wanted to go to a store. 
 
 And in a decision that is every parent’s nightmare, the little boy followed the man from Dawes Park into an alley near his grandmother’s South Side home. The man faced him and shot him in the right temple — execution-style. 
 
 Those were the harrowing allegations that Cook County prosecutors made Tuesday during a bond hearing for Dwright Boone-Doty, a 22-year-old gang member accused of killing Tyshawn to get even with his rivals. 
 
 Prosecutors said Boone-Doty originally planned to torture Tyshawn and cut off his fingers and ears — and kill the boy’s grandmother. 
 
 Boone-Doty, who was charged on Monday with Tyshawn’s Nov. 2 murder — and an earlier shooting that left a woman dead and a man wounded — was ordered held without bail. 
 
 An informant secretly recorded Boone-Doty making incriminating statements about the fatal shootings, sources said. 
 
 Boone-Doty was already in the Cook County Jail on a separate gun charge. An inmate agreed to wear a wire after telling authorities that Boone-Doty bragged about shooting Tyshawn, the sources said. 
 
 Boone-Doty had laughed about the shooting, saying he “seen that bitch go in his head,” prosecutors said, adding that he was writing a rap song in jail that mentioned the killing. 
 
 “It’s hard to accept,” Boone-Doty’s mother, Michelle Doty, told the Chicago Sun-Times. “You don’t think I would try to do all I could to turn my baby around?” 
 
 Cook County State’s Attorney Anita Alvarez called the child’s killing “among the worst I’ve ever seen in my 30 years as a prosecutor.” And Interim Police Supt. John Escalante said: “I have never witnessed such an act of savagery and treachery.” 
 
 Two other men have already been implicated in Tyshawn’s murder. On Nov. 27, Corey Morgan, 27, of Lansing, was charged with murder, and police have a warrant for the arrest of a third suspect, Kevin Edwards, 22. 
 
 Tyshawn, Brianna Jenkins and Deshari Bowens were victims of a gang feud over the murder of Tracey Morgan, 25, authorities said. 
 
 On Oct. 13, Morgan, a parolee, was shot to death and his mother was wounded after they left a police-sponsored meeting intended to resolve gang conflicts. 
 
 His brother Corey Morgan allegedly vowed to target “mothers, grandmothers babies and all” because his brother was killed and his mother was shot. 
 
 Corey Morgan and Boone-Doty — members of the Bang Bang Gang faction of the Black P Stones — were gunning for rivals in the Killaward faction of the Gangster Disciples, who they believed were responsible for Tracey Morgan’s death, prosecutors said. 
 
 On Oct. 18, Jenkins, 19, and Bowens, 20, were sitting in a car about 4:30 p.m. in the 7800 block of South Honore when they were shot, police said. Jenkins was pronounced dead at the scene, authorities said. 
 
 Friends drove Bowens to Advocate Christ Medical Center in Oak Lawn, where his condition stabilized. Boone-Doty said he went to the hospital to finish off Bowens, but was unable to do so, prosecutors said. 
 
 Boone-Doty allegedly said he didn’t know who was in the car before he opened fire, but he thought Bowens was a rival because he shouldn’t have been parked on that block. 
 
 Tyshawn was shot about two weeks later, on Nov. 2, because of his father’s ties to the Killaward gang faction, police said. 
 
 Boone-Doty and Corey Morgan were arrested on gun charges on Nov. 16. Police stopped their car in Evergreen Park and found a loaded .40-caliber handgun in Boone-Doty’s waistband. A loaded .45-caliber handgun was in a duffel bag, police said. 
 
 Lab tests showed one of the guns was used in Jenkins’ killing, prosecutors revealed Tuesday. 
 
 Escalante said the spiraling cycle of gang violence that claimed Tyshawn’s life is all too common in the city, but the grade-schooler’s murder marked a chilling break even from the bloody norms of Chicago’s gang warfare. 
 
 “The murder of Tyshawn Lee was something far more sinister. This was a targeted assassination by Dwright Doty, Kevin Edwards and Corey Morgan,” Escalante said. “Tyshawn was an innocent child betrayed by these three men. Sadly, he paid the ultimate price for gang violence, senseless gang violence, that plagued his neighborhood.” 
 
 Boone-Doty was on parole when he allegedly killed Tyshawn, authorities said. 
 
 He was sentenced to five years in prison in July 2013 for unlawful possession of a firearm by a felon and drug possession in downstate Sangamon County, prison records show. Officers had found a stolen handgun under the seat of a car he was in. They also found cocaine on him. 
 
 He was paroled in August 2015, three months before Tyshawn was lured into the alley in the 8000 block of South Damen and shot to death. 
 
 Boone-Doty is the father of three children, ages 4, 3 and 6 months, an assistant public defender said. Before he was jailed, he worked for his father’s construction company and his grandfather’s landscaping business, his attorney said. 
 
 Boone-Doty completed 10th grade and has a certificate in technology. 
 
 He appeared in court in an orange jumpsuit. A group of deputies stood behind Boone-Doty while prosecutors detailed the horrifying allegations against him. 
 
 Despite sunny skies and temperatures that reached into the 70s on Tuesday, there were few visitors to Dawes Park, where Tyshawn had been playing on Nov. 2. 
 
 “Probably a lot of people are still afraid to bring their kids to the park,” said Korey Baker, who sat on a jungle gym with his girlfriend as their 10-year-old clambered overhead. 
 
 “I came to this park growing up. It’s a shame. It’s like people don’t respect children anymore. Chicago’s getting to be a bad place,” said Baker, a security guard. 
 
 Baker lamented that Tyshawn’s death forced him to share some hard truths with his young son. 
 
 “I told my son, ‘There are monsters out there. You have to listen to mommy and daddy.’ I was sorry to have to tell it to him like that, but I don’t want him to think we live in some dream world.”
– The man charged with murdering a 9-year-old boy in Chicago allegedly "laughed and bragged" about the killing while in jail, DNAinfo reports. Prosecutors say 22-year-old Dwright Boone-Doty lured fourth-grader Tyshawn Lee into an alley in November and shot him as part of an ongoing gang feud. According to the Chicago Tribune, an informant in jail while Boone-Doty was being held on an unrelated gun charge was wearing a wire while Boone-Doty discussed the shooting. "Shorty couldn’t take it no more," prosecutors quote Boone-Doty, allegedly describing Tyshawn during the shooting. Tyshawn was shot in the head, back, and arm; part of his thumb was also shot off. Evidence from the scene indicates Boone-Doty likely failed to kill Tyshawn with his first shot, the Chicago Sun Times reports. Prosecutors say Boone-Doty was writing a rap song about killing Tyshawn while in jail and was sorry he didn't go back to the park where he found Tyshawn to kill more kids. Authorities also claim Boone-Doty—along with two alleged accomplices—at one point planned to kidnap Tyshawn and cut off his ears and fingers. Tyshawn was a backup target after killing his grandmother didn't work out, prosecutors say. A second man has been charged in the killing; a third is still wanted. Boone-Doty was charged with Tyshawn's murder—as well as the murder of a 19-year-old woman weeks earlier—on Monday. The father of three was ordered held without bail. Police say Tyshawn's father belongs to a rival gang.
