Bail remains at $1 million for 32-year-old Andrew Dempsey until his next court appearance Oct. 25 in King County Superior Court in Kent.
Prosecutors say Dempsey was already inside the bathroom at a Burien Albertsons on Sept. 29 when the boy came in. After the boy left a bathroom stall, he said Dempsey -- who was a complete stranger -- grabbed him by the head and threatened to kill him.
Dempsey then put the boy in a headlock and began dragging him into a large bathroom stall, according to court documents. Dempsey, who was naked from the waist down, repeatedly told the boy he was going to kill him.
The boy broke away and ran to the door, but police say Dempsey was able to slam the bathroom door shut on the boy's hand before he could escape. A witness inside the store saw the boy's hand in the door and heard screams for help.
That man opened the bathroom door and saw Dempsey -- with his pants around his ankles -- holding the victim in a "bear hug."
Several store employees and witnesses confronted Dempsey and held him until police arrived.
Dempsey had a bag containing methamphetamine, according to investigators. He told police he had been homeless in Burien for several years and denied attacking the boy.
