A man accused of killing his roommate in a Riverton home now faces a formal murder charge.

Riverton Police Captain Eric Murphy said Tuesday afternoon that 27-year-old Florin Brandon Wyatt is charged with second-degree murder in the killing of his roommate, whose name has not yet been released.

An autopsy is scheduled for Wednesday.

The victim, who was in his 50s, was found dead in his home Sunday morning. It was immediately apparent to officers who arrived on scene that the circumstances were suspicious, Murphy said.

Wyatt was arrested outside Cheyenne by the Wyoming Highway Patrol. He was reportedly in the victim's vehicle en route to Nebraska when he was apprehended.

Wyatt is in custody at the Laramie County Detention Center.
