On Wednesday, Bosleys family and friends returned to the scene at 116th and Halsted to call for justice.
"We want people to speak out, they know who murdered him," said Pamela Bosley, mother. "This is a busy street. We want them to speak up today, and we're offering a $5,000 reward for any lead so we can get justice."
A freshman at Olive Harvey College, Bosley was heading into choir practice at the Lights of Zion Missionary Bible Church on Halsted and 116th streets when he and a group of friends were shot at while unloading equipment from a car. He was killed. A fellow musician was injured but survived.
"He crawled in the door and grabbed my leg, told him it was going be OK and called the ambulance," recalled Darien Mickens, friend.
"He was on safe ground. This is a church. This is church ground," Pamela Bosley said. "I had talked to him 30 minutes before he was shot. 'Mom, you always worry. I'm at church, calm down. I'm going to be OK.'"
Though 27-year-old David Stanley was charged with the murder not long after the shooting, there was never any physical evidence to connect him with the crime. He was acquitted in 2008.
Since then, Bosley's parents have been passing out fliers in the neighborhood around the church, hoping that despite the passing of time, they will find someone who knows something about who killed their son.
"We will be doing this until we get closure," said Tom Bosley, father. "We know that there are some people that are out there that know what happened. As a parent, you just can't give up, you can't give up. We'll never give up."
The Bosleys and a group of about 25 people were canvassing the neighborhood on Wednesday evening.
The investigation is in the hands of the cold case unit.
