Missouri man arrested in murder of 9-year-old Ferguson girl shot while doing homework in home BY Nina Golgowski NEW YORK DAILY NEWS Thursday, August 27, 2015, 5:21 PM A A A Share this URL A 21-year-old man has been arrested in the shooting death of a 9-year-old girl inside of her Ferguson, Mo., home last week, with police revealing he was on probation for another gun-related incident at the time. De'Eris M. Brown was arrested Wednesday and charged with second-degree murder, among other charges, in the Aug. 18 shooting that killed Jamyla Bolden and injured her mother, police said. Investigators said that they don't believe Brown, who they say confessed to the shooting, knew his victims when he fired multiple shots while standing alone outside the family's home around 9:30 p.m. They declined to say whether it was a targeted attack, saying that it's still under investigation. De'Eris Brown, 21, is charged with unlawful use of a weapon: shooting at a building, armed criminal action, second-degree murder, armed criminal action, and unlawful use of a weapon. "We hope that it will bring some semblance of closure, for them," Ferguson's Mayor James Knowles said of Jamyla's family at a press conference Thursday. Brown was apprehended in an area outside of a hospital, which police declined to specify. His arrest comes a little more than a year after he was arrested for reportedly threatening his ex-girlfriend with a gun at a Subway restaurant. "I'm coming to your job and going to shoot up the place," he allegedly told the woman before meeting her in a nearby parking lot and assaulting her. At the time of that May 2014 incident, he was on bail for an armed robbery he committed three months earlier, the St. Louis Post-Dispatch reported at the time. KMOV reported that charges in the Subway assault were dismissed because prosecutors said the victim would not cooperate. Earlier this year he pleaded guilty to robbery charges and was sentenced to 10 years in prison. That sentence was suspended, however, and he was placed on five years probation. His new charges in last week's shooting include unlawful use of a weapon for shooting at a building, armed criminal action, armed criminal action, and unlawful use of a weapon. He's being held on $750,000 cash-only bail.
