UPPER MARLBORO, Md. (WUSA9) -- A Prince George's County jury has convicted a Maryland man of first degree murder for the 2011 killing of a 17-year-old boy, officials said.
It took a jury less than 90 minutes to find Kelvin Delonte Walker, 23, guilty for the murder of Justin Isaacs, according to officials.
On October 10, 2011 at about 7:30 p.m., Issacs was walking home from the library when confronted by Walker and another individual, Tyrone Lewis, officials said.
The two men demanded property from the victim, who ran up a flight of steps leading to his home in the 2100 block of Iverson Street. Lewis grabbed Isaacs who Walker then shot four times with a gun that had been stolen from the car of an off-duty Florida police officer, officials said.
Walker and Lewis took a gold chain and money from Isaacs and fled. His mother heard the shots and found Isaac on the steps. He was pronounced dead shortly after, officials said.
Walker later bragged about the killing and said he did it to prove he was a killer, officials said.
Walker is scheduled to be sentenced on September 18 and faces a potential maximum penalty of Life plus 20 years. Lewis is scheduled to go on trial in February 2014.
