A Southern California man whose abandoned car was located near Pacifica is suspected of his wife's murder, police say.
The San Francisco Police Department is asking for the public's help in finding Billy Waterman, 59, who was originally named a person of interest in his wife's death after she was in a hotel room in San Francisco's Marina District in February.
Prior to discovering the body of Colleen Waterman, 47, San Mateo County sheriff's deputies found the car of the missing Riverside County couple parked and unoccupied on Highway 1 near Devil's Slide on afternoon of Feb. 10, the San Mateo County Sheriff's Office said.
The San Francisco medical examiner's office ruled Colleen's death suspicious at the time, said San Francisco police Lt. Lyn Tomioka.
Investigators have since obtained a homicide arrest warrant for Waterman, police spokesman Officer Carlos Manfredi said.
The couple lived in Riverside County, and both had been reported missing by family members prior to the death.
Billy Waterman is described as a white man about 6 feet tall and 160 pounds, with red hair and blue eyes.
He is known to have family members in Southern California, according to police.
Anyone with information about Waterman's whereabouts is urged to call San Francisco police at (415) 553-1071 or police homicide Inspectors Dudet, Dudoroff or Velarde at (415) 553-1145.
