AMERICAN FORK — A clerk who was shot multiple times at a gas station Christmas Eve remains in critical condition as police continue to search for the shooter.

Tina Marie Lowe, 39, was found wounded by a customer at Tesoro Fast Gas, 312 NW State, shortly before 6:45 a.m., American Fork Police said.

Police originally believed the incident to be a possible robbery, but American Fork Police Lt. Gregg Ludlow said later Saturday that they believe it was an incident of domestic violence.

The lieutenant said the investigation led them to search for Lowe's estranged husband, Michael Darrin Lowe, in connection with the shooting.

"Michael Lowe is considered armed and dangerous and possibly suicidal," Ludlow said.

Police investigations have "shown an ongoing history of domestic violence related incidents which unfortunately have not been reported to law enforcement," he said.

"As an agency, we want to encourage anyone in this circumstance to seek help from law enforcement regardless of any past history, background or circumstances," Ludlow said.

Late Saturday afternoon, police located Michael Lowe's vehicle abandoned in Lehi.

The Lehi and American Fork police departments, the Utah County Sheriff's Office and Utah Department of Public Safety searched the area but weren't able to find Michael Lowe.

Tina Lowe was transported to a local hospital. She underwent extensive surgeries throughout the day, police reported, and was listed in critical condition late Saturday night.

Ludlow expressed condolences to families who experience tragedy during the holiday season.

The lieutenant also urged anyone who might know more about Michael Lowe's whereabouts or the incident to contact American Fork Police at 801-763-3020.
