SEATTLE – Bail has been set at $2 million for the 43-year-old son of a couple who were killed in their home near Kent.

A King County judge found probable cause Thursday to hold Vincent W. Housley, who is being held for investigation of two counts of second-degree murder.

Sheriff’s detectives arrested Housley Wednesday night at a motel in Tukwila.

Court documents say investigators believe the killings happened after a verbal argument. The documents say Housley pushed his mother, 67-year-old Karen Housley, down a flight of stairs, then did the same to his father, 66-year-old Joe Housley.
