PRINEVILLE, Ore. -

A Crook County jury took about 3 1/2 hours late Monday to convict a Prineville man of first-degree manslaughter, but not murder, in the November 2009 shooting death of his roommate at a trailer park.

District Attorney Daina Vitolins had sought the murder conviction of Richard Lynn Breneman in the killing of Voy Douglas Powell in their home at the Easy Living Trailer Park on SE Combs Flat Road.

But the jury instead sided with the defense and found Breneman guilty of manslaughter, meaning it believed he ?unlawfully and recklessly? caused Powell?s death, but not intentionally, Vitolins said.

Breneman had a blood alcohol content of 0.18 at the time of the shooting. An autopsy of Powell showed his blood alcohol content at about 0.23.

Sentencing is set for July 28th at 11:30 a.m. before Circuit Judge Gary Williams, who presided over the trial that began on July 5 -- and apparently was the first murder trial in Crook County in 32 years.

The trial had been delayed last week when the defense lawyer lost his voice, the DA said, noting that under Measure 11, he faces a 10-year prison sentence. The murder charge as sought would have carried a 25-year sentence, Vitolins said.

The shooting prompted a three-hour standoff and SWAT team call-out before Breneman surrendered to authorities. He had threatened to shoot officers if they entered the trailer to take him into custody.

The Central Oregonian reported a month before the shooting that an altercation between the two men led to Breneman being charged with four-degree assault, strangulation and harassment.
