Police ask for public's help finding Centennial man's killer
Arapahoe County Sheriff Grayson Robinson hopes to release video from the County Line light rail station to the media as early as Tuesday, in the hopes someone will recognize other people on the tapes or that those people wil come forward to talk.

Sheriff's Investigators are going frame by frame over video surveillance both from the County Line station and the one at Dry Creek, as well as trains 23 year old Andrew Graham was on Thursday night.

He was last seen exiting the train at County Line at 11:40pm Thursday.

"We don't believe those people had any involvement with his death," said Sheriff Grayson Robinson, "But we certainly would like to talk with them about the activities on the train what they may have seen in the general area of the train platform those kinds of things."

Graham's body, with a single gunshot wound to the torso was found just over a mile away at the southern edge of the Willow Creek neighborhood where he lived with his family.

"Please anyone who knows anything please, please call us and let us know," pleaded Cyndi Graham as she tearfully asked for the public's help in an emotional news conference on Sunday.

Graham says her son, who was to begin graduate school at CU in Janurary, would have avoided confrontation but was always willing to help others.

One big question, why did Andrew Graham get off the train at County Line, when he always uses the Dry Creek Station.

Other light rail passengers at County Line were talking about the case Monday night.

"I kinda felt good about being around here at night but not anymore," said a 17 year old girl who didn't want us to use her name.

"He was found a ways away from here but it does suprise me that it was around here," said a woman catching a bus after getting off the train.

"You don't get a lot of traffic and a lot of people noticing things so maybe somebody who saw something might not be willing to stop," said a man who uses catches the train here every day.

Police will not discuss exactly where Graham's satchel with all his personal information and cash were found along his route home, but it is almost certain to be a crucial part of their investigation.

Several neighbors in the area say they heard gunshots after midnight late Thursday and investigators plan to test gunshot sounds in the area over the next few days to try to pinpoint a location where Graham may have been shot.
