A 43-year-old man from the Lake Arrowhead area died after San Bernardino County sheriff’s deputies used a Taser to subdue him after a traffic stop, authorities said Wednesday.

A deputy attempted a traffic stop on Allen Kephart, a local DJ and teacher’s assistant from Crest Park, after he allegedly ran a stop sign Tuesday on Highway 189 in Blue Jay, said Cindy Bachman, a Sheriff’s Department spokeswoman.

Kephart pulled into a Valero gas station parking lot about a quarter mile away, got out of the car and "became combative and uncooperative" with the deputy, Bachman said. Additional deputies arrived at the scene to assist, she said.

"The deputy attempted to place him under arrest, at which time he was Tased," Bachman said. “He became unconscious, and medical aid was immediately provided -- CPR."

Kephart was taken to a local hospital, where he was declared dead.

Kephart’s father, a member of the Sheriff’s Department’s volunteer mounted Rangers unit for decades, called his son’s death a senseless use of excessive force. The incident happened when his son was returning to the family home after filling up his car with gas in Crestline.

"To me, it’s not just a traffic stop. It’s murder. You don’t kill a person for running a stop sign," said Jack Kephart, also of Crest Park.
