The man who admitted he sold a gun used in the Trolley Square shooting that left five patrons dead and four others wounded was sentenced today to 15 months in federal prison.

After completion of the prison term, Mackenzie Hunter will be on supervised release for 36 months.

U.S. District Judge Dale Kimball stressed that while the Feb. 12, 2006 shooting by Sulejman Talovic was a tragedy, Hunter's actions had nothing to do with that crime.

Eight months before Talovic went on the shooting spree, he bought a .38 Special from Hunter for $800. Federal authorities have said Hunter, 20, thought the gun was going to be used in a robbery.

The parents of one of the Trolley Square victims, Vanessa Quinn, had sought to be present at today's sentencing, arguing unsuccessfully that their daughter's death was connected to the sale of the gun.

On Friday, the 10th U.S. Circuit Court of Appeals rejected their efforts to be declared "victims" in the case, saying they had failed to prove that connection.

Although sympathetic to their request, justice said they failed to show a direct link. One justice blamed that failure on the U.S. Attorney's Office, saying the the process of providing information to Quinn's parents had failed to adequately support the rights of crime victims.
