Two teenage suspects have been charged in the fatal shooting of U.S. Rep. Danny Davis' grandson, Chicago police announced Sunday.

Tariq Harris, 16, and Diajae Banks, 17, were charged as adults with first-degree murder and home invasion in the death of 14-year-old Javon Wilson. Both were denied bail on Sunday.

Wilson was shot and killed Friday evening in a "dispute over gym shoes," according to Chicago police. He was inside his home in the 5600 block of South Princeton Avenue in the Englewood neighborhood on the city's South Side around 6:45 p.m. Friday when two teenagers forced their way inside, authorities said.

During a confrontation that followed, police said one of the teens pulled out a gun and shot Wilson in the head. Officials initially investigated the incident as a home invasion, but CPD spokesperson Anthony Guglielmi tweeted Saturday morning that the shooting was "not random," confirming that it was a dispute over shoes.

Wilson was a sophmore at Perspectives Charter School whose grades had recently improved, according to his family.

"I do know that I grieve for my family," Davis said in a news conference after the shooting. "I grieve for the young man who pulled the trigger, I grieve for his family, his parents, his friends, some of whom will never see him again."

Davis said two of Wilson's brothers, ages 14 and 8, a 16-year-old sister and an uncle were all in the home at the time of the shooting, while his mother had left the house to get some food.

"Here he was in the house, in his home, minding his own business and some intruders would come and snuff his life away," Davis said, adding that better education, supervision and parenting might have prevented the killing.
