Colorado Springs police issued an arrest warrant on suspicion of attempted murder for a man already serving time in prison.

Luke Johnson, 30, was identified as the main suspect in the 2011 attempted murder of a woman two years after the case went cold from lack of evidence. Johnson is incarcerated at the Sterling Correctional Facility for escaping from Alamosa Community Corrections, police said.

In 2011, a woman was found by 30th Street and West Pikes Peak Avenue severely bleeding from the head. The woman was only able to tell police that her boyfriend had attacked her, but could not give them an accurate description of the man or details of the incident.

A short time later, police heard that a man, identified as Johnson, had been overheard in a phone conversation at a 7-Eleven store, talking about beating someone to death.

Police interrogated Johnson and tied him to a stolen truck in which blood was found. The victim's inability to positively identify him as her attacker halted the case and it went cold, police said.

Detectives collected samples of the blood found in the stolen truck and submitted it to the Colorado Bureau of Investigations for analysis and comparison with the victim's blood.

In May of this year, Colorado Springs police detectives received the results of the blood tests, revealing the samples collected from the truck matched the victim.

An arrest warrant was issued for Johnson Thursday on suspicion of attempted murder. He remains incarcerated in the Sterling Correction Facility until the District Attorney's Office files formal charges.
