The 50-year-old man accused of driving into a bicyclist early Saturday and leaving him to die has two previous convictions for drunken driving, according to Colorado court records.

Mark L. Doutt, who is suspected of ramming cyclist William Byas, 44, from behind on South Circle Drive just after midnight, was arrested for DUI in El Paso County in September 1987 and in Teller County in May 2006. He pleaded guilty both times.

Colorado Springs police spokesman Sgt. Darrin Abbink said it is unknown if drugs or alcohol were involved in the hit-and-run death.

“Proving it may be impossible even if it is suspected, because of the time difference,” Abbink said.

Doutt was arrested around noon Saturday at a home in 700 block of Squire Street in Widefield on suspicion of leaving the scene of a crash involving death. Police are seeking witness accounts of Doutt’s whereabouts and actions Friday night.

Police received several tips about Doutt’s possible involvement in the crash.

If Doutt was behind the wheel of the car that struck Byas, he only made things worse for himself by leaving the scene of the crash, Abbink said.

Leaving the scene is a Class 3 felony, a more severe charge than he would face if alcohol or reckless driving were involved and resulted in a charge of vehicular homicide, a Class 4 felony, Abbink said.

Doutt is being held in the El Paso County jail on $10,000 bond. He was scheduled for an advisement hearing in 4th Judicial District Court at 1:30 p.m. Monday.

Police said Byas died at the scene from an apparent spinal injury.
