SALT LAKE CITY (ABC 4 Utah) - The accused cop killer believed to be responsible for the death of a Draper police officer is now behind bars and is formally being charged with murder. Prosecutors said Troy Walker shot and killed Sgt. Derek Johnson, and Wednesday they filed charges.
Walker was just released from the hospital Wednesday, and transferred to the Salt Lake County Jail. At the same time, the Salt Lake County Dist. Attorney filed murder charges against him, and he's facing the possibility of severe punishment.
The man prosecutors claim shot and killed Draper Sgt. Derek Johnson is now being charged with his murder.
"It's alleged that the defendant continued to fire multiple shots at the vehicle," said Sim Gill, Salt Lake Co. Dist. Attorney.
Salt Lake County Prosecutor Sim Gill said 34-year-old Troy Walker is now facing six felonies, including illegally firing a gun, the possibility of attempted homicide, and aggravated murder.
"That leaves open the option of the death penalty in the prosecution of this case," said Gill.
Gill said the morning of September 1st Walker's Volvo ran out of gas near 132nd South and 9th East in Draper. Walker was outside the car, when Sgt. Johnson pulled up alongside him in his police vehicle. That's when prosecutors said Walker shot Johnson, and his on-again off-again girlfriend Traci Vaillancourt who was also in the Volvo, before finally turning the gun on himself. Prosecutors was said Walker was high on drugs at the time.
"That toxicology result showed that there was methamphetamine in his person," Gill said.
Wednesday night Reporter Brian Carlson stopped by Walker's mother's home to see what his family thinks of the charges and new accusations, but no one answered the door.
Prosecutors said because Walker shot and killed a police officer trying to assist someone in distress, they are not planning on taking this case lightly.
"Our office will spare no resources in the aggressive prosecution of this case and to take it to it's logical and just conclusion," said Gill.
As far the death penalty goes, that hasn't been decided just yet. Prosecutors have 60 days after Walker is arraigned on the charges, to announce whether or not they plan to seek the death penalty.
