Police are trying to determine how a motorcycle driver lost control of his bike early Monday morning.
John Edward Smerek, 41, was heading westbound on Peoria Avenue when he somehow lost control near 35th Avenue, hit the median and was ejected from his bike. He landed into oncoming eastbound traffic.
After being ejected, Smerek was run over by a car and his bike was run over by another vehicle.
He was transported to the hospital in critical-condition and later died from his injuries.
Investigators are looking at speed, inattention, other vehicle movement and if impairment may have played a role in the fatal accident.
The investigation is ongoing.
