Graham was last seen alive when he exited a Light Rail train at the County Line station at 11:40 p.m. on Nov. 5. On Thursday night, investigators rode the Light Rail trains from Union Station to County Line. They believe that was the same route Graham took.
Witnesses report hearing the sound of a shot or shots being fired in the area of East Phillips Place and South Yosemite Street. Graham's body was found five hours later by a homeowner.
Investigators also shut down lanes County Line Road. and South Yosemite Street on Thursday night. They handed out fliers to drivers in the area asking for information about the crime.
Earlier in the week, a surveillance tape from inside the Light Rail train where Graham was seen riding was released to the media. Captain Louie Perea with the Arapahoe County Sheriff's Department says no one in that video has come forward.
Anyone with information about the case is asked to contact the sheriff's department at 303-795-4711. A significant cash reward is being offered.
