(KMOV) -- On Wednesday, a jury in Madison County, Illinois found a Pontoon Beach man guilty in the 2008 killing of a 12-year-old boy from Madison.
Jury selection began on February 8, 2012, in Edwardsville, for the October 2008 case against Marcus Powell, 31, of Pontoon Beach, Illinois. Powell had been charged with First Degree Murder and Aggravated Discharge of a Firearm in connection with the murder of 12-year-old DeLarrian Davis.
Davis was shot in the head and killed as he did his homework in his Madison, Illinois home. Shots were fired into the home after an ongoing dispute between Powell and Davis' mother, Sophia Campbell, and step-father, Kevin Campbell.
Kevin is believed to have been the intended target.
Jurors began deliberating around 12:30 p.m. Wednesday and returned with guilty verdicts on both counts around 9:30 p.m.
State's Attorney Thomas D. Gibbons praised the work of prosecutors and police.
"This was a tough case and I'm satisfied that we were able to obtain justice for DeLarrian," said Gibbons.
Gibbons also thanked the jurors for their service.
The maximum penalty for a murder conviction is 20-60 years in prison and 4-15 years on the firearm charge.
Sentencing will be held at a later date after the completion of a Pre-Sentencing Investigation.
In 2007, Powell had been charged in St. Clair County for shooting Sophia Campbell. Powell was also sentenced in federal court this past summer for dealing crack cocaine and received a 35-year sentence.
