Brian Loncar, the well-known plaintiffs lawyer known in Texas for his “Strong Arm” television commercials who was found dead a week after his daughter’s suicide, died of an accidental cocaine overdose, according to the Dallas County Medical Examiner’s Office.

Loncar launched his law firm Brian Loncar & Associates in the late 1990s and became one of the most aggressive personal injury advertisers in North Texas, winning thousands of new clients each year with his promise of being the “Strong Arm” for car-wreck victims and getting them the money they deserved.
