(CNN) -- Police say the 68-year-old Merrill man who caused a deadly crash on Saturday was having a heart attack, which likely caused him to run a stop sign.
Marc Bingham was driving west on Vasold Road when he ran the stop sign at North Gleaner Road in Tittabawassee Township around 5:50 p.m. Saturday. He collided with the passenger side of a northbound vehicle.
Bailee Mantei, 14, died on the scene and her father, 42-year-old Matthew Mantei of Freeland, suffered serious injuries. Bingham died at Covenant HealthCare hospital after the crash.
Autopsies conducted this week determined Bingham was suffering a massive heart attack when the crash happened, which caused his death, according to the Tittabawassee Township Police Department.
