Panama City police say a 44-year-old Altha man died Wednesday night in a truck accident on Highway 231 north of Transmitter Road in Bayou George.
It happened a little before 6:30 p.m. in the northbound lanes of Highway 231.
Officers say a commercial cleaning van ran off the road and plowed into a line of trees on the east side of the highway.
The driver, 44-year-old Charles Wilson of Altha, slammed into the windshield. The impact of the collision sent dozens of boxes of cleaning supplies hurtling from the back of the van a split second later. The driver was hit from behind by this second impact.
Wilson died at the scene. Investigators are still trying to find out what caused the man to leave the roadway.
This was the second highway death in about two hours, both happening within a few miles of each other.
In the earlier case, a man with a history of heart problems apparently had a heart attack while driving northbound just past the intersection of 231 and Transmitter Road.
Panama City police say the man managed to pull onto the side of the road, but he died before help could arrive. They have not released his name.
Between the two traffic incidents, northbound traffic on Highway 231 was backed up for most of the afternoon and evening
