(KPLR) - The Museum of Transportation is mourning the death of a volunteer after what they are calling a tragic accident
The museum's president says Eric Hesselbarth died Thursday from a head injury.
He was working on restoring a 1937 milk delivery truck and while filling up the tires, one of them exploded. A piece of the wheel hit Hesselbarth in the head.
Hesselbarth had been volunteering with the museum for over ten years.
The area where the accident happened has been closed.
