want to yepdijeopardize it righ now. reporter: what role did they play in this, and what about mr. edwards? well, it s a little bit i don t to want say unclear but it depends on who s speaking who did what. at this moment i don t think we want to reveal any of that, right, chief? there were three people, we re pretty certain, acting in concert. let s put it that way. who pulled the trigger is all being worked on to delineate it. we do know, in fact, these are the individuals who were involved in this. reporter: did one lead the victim from the apartment into the alley and the other two were involved? he was definitely lured from the park where he was playing basketball with some friends. i guess that s the best way to describe it. reporter: can you describe the background?
