BRYAN (August 9, 2012)—Department of Public Safety investigators say a witness has come forward with information that could help them track down a driver who didn’t stop after a piece of angle iron flew off the trailer his truck was towing and crashed through the windshield of an oncoming pickup, killing the passenger.

Tracey White, 33 of Bryan, was pronounced dead Sunday at a hospital after the accident on State Highway 21 between Bryan and Madisonville.

The driver of the pickup, Charles Robert, 35, wasn’t injured, KBTX-TV reported.

"We had basically a piece of metal that we had to match to something. We didn't know what we were trying to match that metal to,” Department of Public Safety Trooper Jimmy Morgan told KBTX.

Authorities say a man from Louisiana who witnessed the incident has since provided a description of the truck and trailer.

He told investigators he saw a piece of metal fly off the trailer, but didn’t realize at the time that it hit anyone.

"He thought maybe it hit the truck, maybe the truck had some damage or whatever, but he had no idea it actually hurt anybody,” Morgan told KBTX.

The man said the truck that was towing the trailer was a white pickup that may have been a three-quarter ton extended cab.

He said two men were riding in the truck and said both were white and around 50 years old.

He told investigators the truck was towing a dark-colored gooseneck trailer that was carrying at least two round bales of hay, and a hay rake implement.

Initial reports had indicated the angle iron flew came from an 18-wheeler.

Investigators reviewed video from a surveillance camera at a small bank in Kurten and say they saw a truck that matches the description provided by the witness.

Troopers want to talk to the driver of the truck in order to determine whether charges will be filed.

The Department of Public Safety is asking anyone who may have witnessed the accident to call the Bryan Highway Patrol Office at (979) 776-3101.
