Snoqualmie police are in their second day of a search for a vanished Clyde Hill man last seen at the Mount Si Golf Course.

Wayne “Lee” Singleton’s last known whereabouts were the golf course restaurant, where he dined shortly after noon Monday, Nov. 8.

North Bend Police Chief Mark Toner reported that his car, a Mercedes S-550, was still parked near the golf course on Tuesday morning.

Snoqualmie officers, King County Sheriff’s deputies and Search and Rescue team members have been combing the marshy areas surrounding the course since Tuesday, police spokeswoman Becky Munson said. Searches using both a helicopter and police dogs have so far been unsuccessful.

Singleton requires blood pressure medication daily, police said.

Anyone who may have seen Singleton at the course, restaurant or any other location after 12:30 p.m. Monday is asked to call either the Snoqualmie Police Department at (425) 888-3333 or the Clyde Hill Police Department at (425) 454-7187.

Mount Si Golf Course staff said Singleton usually plays at the course a few times a year.

Clyde Hill is located near Bellevue.
