Police had been repeatedly called to the home of Shane Hathaway, a Mill Creek man who is suspected of killing his grandmother last week, according to a court document released Tuesday.
“During at least two of the police contacts, officers were so concerned for the safety of the (grandparents) they expressed their concerns to them,” police wrote in an affidavit of probable cause laying out the state’s case. “Officers told (the grandparents) that Hathaway could really hurt them because he is so much younger than them, his size, and his mentally instability.”
But the suspect’s grandparents remained loyal to the 24-year-old man, who had been diagnosed with schizophrenia and bipolar disorder and had a history of drug abuse, according to the affidavit. The man lived with his grandparents in their Mill Creek home.
A judge found probable cause to hold Hathaway on investigation of second-degree murder and attempted second-degree murder. A judge set bail at $2 million on Tuesday.
Police were called to the Mill Creek home just before midnight Thursday by Hathaway’s grandfather, who said his grandson attacked him with a knife while he was in his bedroom, stabbed him in the chest and cut his throat, the affidavit says.
According to the affidavit, the grandfather said he was in the bedroom when his grandson threatened to kill him. The grandfather tried to calm the younger man but was attacked, it says.
The grandfather was able to fight off Hathaway, lock the door and call for help, the affidavit says. He told dispatchers he didn’t know where his wife was in the house or if she was harmed.
When police arrived, they found the injured 83-year-old man. His 83-year-old wife had been killed, police said.
The grandfather was listed as being in stable condition on Friday.
Hathaway was arrested by police when he emerged half-naked from nearby the woods around 3 a.m. Friday, the affidavit said. The document says he was wearing no pants or underwear.
Police said the suspect did not speak with detectives before he was booked into the Snohomish County Jail on Friday afternoon.
The Snohomish County Medical Examiner’s Office said the name of the slain grandmother was expected to be released on Tuesday afternoon.
Hathaway had been charged last year with domestic violence against his grandparents, prosecutors wrote in the affidavit. The 2014 charge was dismissed in December after Hathaway’s grandmother appeared in court and spoke on his behalf, court documents show.
In October, Hathaway was convicted of second-degree burglary in Snohomish County Superior Court after he used a hammer to break into DJ Market on Aug. 31, 2013. The convenience store is near the Mill Creek home Hathaway shared with his grandparents.
When police responded to an alarm at the store they found Hathaway “so highly intoxicated he could not speak or stand,” charges said. He smelled of alcohol, and police found four open cans of Four Loko, a caffeinated malt beverage, on the ground, charges said.
