A California mom vanished a day before her car was discovered abandoned on a bridge hundreds of miles from her home, authorities said.

Tiffany Clark, 38, was reported missing Monday after she was last seen heading home from work to Calaveras County, news station KTXL reported.

Her daughter, Michaela Haight, said her mother hasn’t answered her phone and all calls have gone to voicemail.

“I start calling around to all the hospitals, all the jails, all the mental hospitals in every county, Calaveras County, Stanislaus County, everywhere around here trying to find her because nobody has seen her,” Haight said.

Within hours of filing a missing persons report, Haight learned authorities discovered her mom’s car, but there was no sign of her mother.

The black Ford Ranger was located Sunday on Martin’s Ferry Bridge in Humboldt County, more than 300 miles away from Clark’s home, authorities said.

“A neighbor who lived in the area had located a suspicious vehicle parked in the middle of the Martin’s Ferry Bridge,” Samantha Karges with the Humboldt County Sheriff’s Office told KTXL. “What made it suspicious for us was that all of Ms. Clark’s belongings were still inside of the vehicle.”

Anyone with information about Clark’s whereabouts is urged to contact authorities at 707-445-7251.
