Bail was set today at $1 million for a 50-year-old Arlington man who is suspected of killing his sister after the death of their mother on Saturday.
The siblings had previous arguments about their parents’ wills, police say in court documents.
According to documents filed in Snohomish County courts, the siblings’ mother was reportedly found dead at the bottom of the basement stairs in the home she shared with her son in the 13200 block of 240th Street Northeast on Saturday morning.
The victim’s son became concerned when he learned of his grandmother’s death on Facebook.com, but could not locate his mother. He went to his uncle’s house, where his uncle told him his mother had left after having an argument with a neighbor, court documents say.
When the woman remained missing on Sunday, her son returned to his uncle’s house and found his mother’s car parked behind the barn, court documents say. The driver’s seat was pulled back further than usual and inside there were cash withdrawal receipts and alcoholic beverages that his mother did not drink, according to the certification of probable cause.
Investigators with the Snohomish County Sheriff’s Office said that when they responded to the son’s 911 calls on Sunday, his uncle was found semi-conscious in his car with a beer in his lap and a hose attached to the exhaust pipe and routed into his closed car. In addition, they found the body of a woman covered with a blanket on the man’s property, court documents say.
The man was arrested on investigation of second-degree domestic violence murder in the slaying of his sister and is in custody at Snohomish County Jail.
Positive identification of the body, as well as determination of the cause and manner of death, will be handled by the Snohomish County Medical Examiner’s Office. The death of the suspect’s mother will also be re-examined, according to the sheriff’s office.
