Pittsburgh Armored Truck Slaying and Robbery

March 1, 2012— -- A fugitive armored truck employee who allegedly killed his co-worker before running away with about $2.3 million called a friend and admitted to the killing, police say.

Police have been searching for Kenneth Konias Jr., 22, since the Tuesday afternoon death of his co-worker, Michael Haines, 31.

"He had at least a two-hour head start from the time he left work until the time Mr. Haines was discovered," Cmd. Tom Stangrecki of the Pittsburgh Police Department said. "We're not sure if he's in the state."

The FBI is assisting the Pittsburgh Police Department in the search for Konias, Stangrecki said.

The two men worked for Garda Cash Logistics and were collecting cash from the Rivers Casino and a Home Depot in Pittsburgh.

Haines' roommate of seven years, Joe Krsul, told ABCNews.com his friend and Konias worked together "a couple of times a week". Haines never expressed concern about Konias, but said he preferred working with the veteran guards.

"He said he felt the younger gyus didn't know what they were doing," Krsul said.

Slumped over with a gunshot wound to the back of the head, Haines' body was found in the idling armored truck two hours after police believe Konias shot him to death. At least $2.3 million was missing from the truck.

He fled the scene but made a phone call to a friend, which was outlined in the criminal complaint charging him with homicide and robbery.

"At the time of this conversation with Kenneth Konias, Konias made statements such as, 'I (expletive) up. My life is over,'" the criminal complaint stated.

After the friend asked Konias a series of questions probing what was wrong, the friend, who is identified as Witness #1 in the criminal complaint, said, "What, did you kill someone?"

After a few seconds of silence, Konias allegedly said "yes" and implored his friend to run away with him and live off the money from his heist.

Garda, the company for which both men worked, is offering a $100,000 reward for information leading to the conviction of the person responsible for Haines' killing and for the return of the stolen funds.

"We are deeply saddened at the death of our colleague and extend our condolences to his family," Garda said in a statement. "We are continuing to assist law enforcement in its investigation of this incident."

Haines was remembered as a "good guy" who was "like a brother" to Krsul.

"He was a very honorable guy...one of those guys you don't see too much around," Krsul said. "And he wore his badge with honor."
