View Larger MapThe Mercer Island man wanted for brutally assaulting his ex-girlfriend on Wednesday was found dead from an apparent suicide early this morning. Police believe that at around 5pm yesterday, Jay Blake Williams confronted his former girlfriend after waiting for her in the Bellevue Commons parking lot outside her workplace. According to police, Williams threatened to kill her, then struck her several times in the face with a gun. She escaped back inside to call police, but by the time they arrived, Williams had already disappeared from the scene. A BPD officer spotted Willams’ van in a parking lot of a Bellevue office park while on patrol around 1:30 am this morning. A search of his home on Mercer Island hours earlier turned up a suicide note. He was discovered on the floor of the van, having suffered a gunshot wound to the head.
