A Casper man is accused of killing his roommate during an argument and fight.

Thirty-seven year old Donald Johns has been charged with first degree murder, in the death of 49 year old Donald Wickersham.

Investigators with the Casper Police Department say at around 11 p-m on Saturday, August 29th, neighboring apartment tenants on the 300 block of North Jackson Street told police that Johns and Wickersham were arguing, and several thuds and knocks could be heard.

Johns and Wickersham had been known by other neighbors to argue, and become violent and fight when they drank in the past, but this particular instance was more intense than usual and both had been drinking earlier in the evening.

Police found Wickersham dead in his apartment the next day, and determined he was stabbed 20 times, and that the attack took place in three rooms.

Officers found two smears on the bedroom carpet at the apartment, which appeared to be caused by someone wiping their shoes on the carpet.

They also found a knife in a dumpster, and blood splatter on the rear stairwell of the apartment.

Johns later contacted investigators to have them pick him up.

He had a cut on his finger, as well as bruising elsewhere on his body, as well as blood on his shoes and clothing.

Two neighbors told investigators that Johns had stopped by on the night of the attack, and they helped him clean up and dispose of bloody rags, but they did not know what had happened, nor did Johns say anything.

Police collected the rags and some blood stained clothes, which others say Johns was wearing on the night of the attack.

Johns' ex-girlfriend told investigators that Johns had stopped by her place after the attack and said that he had killed Wickersham.

Johns is being held on $1,000,000 bond awaiting trial.

Prosecutors have said at this time, they will not seek the death penalty, which means he could get up to life in prison without parole if convicted.

Johns has a number of violent felony convictions out of California and Texas.
