Daniel James Burda, 36, was taken into custody Friday on suspicion of manslaughter, criminally negligent homicide, abuse of a corpse, criminal mistreatment and identity theft in the death of Dennis Day, Oregon State Police said.
Burda was being held in Jackson County Jail, where records show he had been booked on June 26 for violating probation on a previous robbery charge.
It was unclear if he has an attorney.
Oregon State Police Captain Timothy R. Fox said Burda did jobs around the house for Day and his husband. Police declined to provide more details about Burda’s connection to Day, though neighbors say Burda had lived with the elderly couple at their home in southern Oregon.
Day, 76, was a founding member of the Mickey Mouse Club for two seasons in the 1950s.
In February, members of Day’s family spoke with "Dateline," a television news show, and said the investigation into Day’s disappearance had been poorly handled.
Day was first reported missing last July 15 by his husband, Ernie Caswell, who has memory loss.
Day’s car was later found at the Oregon coast and a missing person report said Day had uncharacteristically left his dog with a friend on the day he disappeared.
