Mounties say they are increasingly concerned about the welfare of a missing 18-year-old after her cell phone was discovered outdoors Sunday morning.

Tyeshia Jones was last seen leaving a friend’s house party in the 5000-block of Miller Road in Duncan, B.C. some time around 2:30 a.m. Saturday.

Her friends say she was heading to a Real Canadian Superstore to meet a guy, but never showed up.

Cpl. Kevin Day says her cell phone was found the next day by a caretaker outside the Yuthuythut Adult Learning Centre on River Road.

“Search and rescue are busy scouring the area,” he said. “Hopefully they will come up with some clues.”

Police have searched Jones’ bank and phone records, but say they have found no activity since a text message sent at 3 a.m. from August Road.

“We’re still looking further into the records from the phone companies. These things unfortunately sometimes take a little bit of time,” Day said.

Her mother says it’s not like Jones to disappear, and she’s worried for her well-being.

Jones is described as a 120-lb. First Nations woman with long black hair and braces. She was last seen wearing a black jacket, blue jeans and black boots.

Anyone with information on her whereabouts is asked to call the North Cowichan/Duncan RCMP at 250-748-5522 immediately.
