DALLAS -- The man accused of shooting his brother, then reporting it as a suicide, has pleaded not guilty to manslaughter.
Brandon Orosco, 34, of Eugene also entered a not guilty plea to tampering with physical evidence during an appearance in Polk County Circuit Court on Thursday.
Orosco was arrested on Dec. 20 -- nearly a month after the death of Jared Orosco, 30, at the latter's home outside Monmouth.
Brandon Orosco initially told officials Jared had shot himself in the head on Nov. 18 after a day of drinking.
Investigators later found Jared Orosco's blood on Brandon and determined that the .22 caliber handgun that killed his brother was wiped clean of fingerprints, according to court records.
When confronted with the evidence, Orosco relented and said the shooting was accidental and a prank gone wrong, records revealed.
A pretrial conference has been set for Tuesday. A trial has been tentatively scheduled for Feb. 10. The court has appointed Chris Lillegard to represent the defendant. Polk County District Attorney Stan Butterfield will prosecute the case.
