A bail plea for two teenagers accused of fatally shooting a 15-year-old grandson of an Illinois congressman was denied Sunday afternoon. Javon Wilson was killed Friday following an argument over a pair of basketball shoes.

The two accused — a 16-year-old boy and a 17-year-old girl — appeared before Cook County Judge James Brown on Sunday. The judge reportedly called the killing of U.S. Rep. Danny Davis' grandson a "total callous disregard for human life." 

According to local police, the shooting stemmed from a dispute over basketball shoes. Police also said that Wilson knew his attackers and they may have been friends. The accused have been charged with first-degree murder.

Wilson was reportedly home with his 16-year-old sister, his two brothers, ages 14 and 8, Friday night while the kids’ mother went out to pick up dinner. Davis said that the two accused forced their way in the house and argued with Wilson before the boy shot Wilson in the head.

Davis, who was re-elected this month to his 11th term in the 7th Congressional District and is a former Chicago alderman, told the Associated Press on Sunday that the charges brought him continued remorse at the loss of his grandson.

"I feel a great deal of empathy, especially for the families of the two individuals who are involved," Davis said. "I'm sure that's not the way they were hoping to go into their Thanksgiving week."

The politician described his grandson as "a pretty regular kid" who loved playing basketball.

Davis said it's unfortunate the teens "would have access to a gun that could lead to that kind of mayhem" and that he will "continue to work with those who are trying to get guns out of circulation." 

Chicago has seen a drastic rise in the number of shootings and homicides, with August being the deadliest month in the city in two decades.
