SAN ANGELO, Texas — San Angelo police are investigating a two-vehicle collision that occurred at the intersection of North Bell and Hughes streets late Thursday afternoon.

"When units arrived, they located a man that was badly injured. He was actually being treated by fire department personnel who happened to be nearby when the crash occurred, thank God," San Angelo Police Department Public Information Officer Tracy Piatt-Fox said. "That man was transported to Shannon Medical Center with incapacitating injuries."

The preliminary crash investigation showed a 1992 Chevrolet Silverado pickup truck was traveling northbound on North Bell Street and was about to turn westbound onto Hughes when it collided with a Jeep that was traveling southbound on North Bell.

The force of the collision caused the Jeep to roll several time, Piatt-Fox said. The Jeep came to rest on its side.

"I will say that the driver of the Jeep was ejected, he was not wearing a seat belt, so again, very, very severe injuries," Piatt-Fox said.

The driver of the Jeep is a 37-year-old man. The driver of the pickup is 57, and he was not injured in the collision.

Piatt-Fox said this is still a preliminary crash investigation.

Because the darkness played a factor in the preliminary investigation, Piatt-Fox said investigators will return to the scene Friday to conduct a follow-up investigation in the daylight hours.
