NEWARK -- Police said it could be at least two weeks before authorities determine the cause of death for man and a teenage girl found dead inside a city motel Friday.
"We will not know if it was a murder-suicide or double suicide for several months," Cmdr. Mike Carroll said Saturday.
Police have not yet released the identity of either victim, but the teen's mother told the Pleasanton Weekly that the girl is her daughter, Patricia Martin. The 17-year-old Village High School student had been missing for nearly a week.
Kathy Martin, an executive assistant at the Pleasanton Weekly, reported her daughter missing to Pleasanton police as a runaway Monday, police said. Officers said the mother was unable to provide any information regarding her daughter's whereabouts but believed she was in the company of her boyfriend.
Carroll said authorities were waiting on lab results on the teen and a 24-year-old Livermore man whose bodies were found Friday inside the Newark E-Z 8 Motel at 5555 Cedar Court. Officers responded to the motel at 11:48 a.m. after a housekeeper discovered the bodies in a second-floor room above the motel office, Carroll said.
The man's name has not been released, pending notification of family.
The couple had sustained gunshot wounds and were pronounced dead at the scene. Newark police on Saturday continued to investigate the incident.

Counselors were on hand at Village High School on Saturday, and a handful of students sought them out, principal Greg Giglio said. Grief counselors will remain on the campus this week, he said.
"We're small, 100 students or so, so most everybody knows everybody else," Giglio said. "It's a sad thing."
