DEL CITY, Okla. -- Police are now investigating to find out what caused a man to crash his semi truck into a building.
Oklahoma Highway Patrol said it happened when the driver drove off of I-40 West at the Scott St. exit in Del City just after 5:30 a.m. Thursday.
He hit a vacant building just off the service road.
The man's name hasn't been released we know he works for the Transport One trucking company.
A wrecked out semi rests just feet from Chad Beal's home after it crashed through a nearby building.
"I heard all these crashes and crunch," Beal said. "Then I looked outside the window, and I got a semi in my front yard."
Before the lights of fire trucks arrived, Beal raced outside to check on the driver.
"I tried to get a response from the guy, kind of shook him a little and there was nothing," Beal said.
Paramedics rushed the driver to the hospital where he later died.
Investigators said a medical condition could have caused the accident.
"We got pretty lucky that we didn't have anybody's houses damaged or anybody hurt inside their house and we got lucky the building was unoccupied," Trooper Joey McLaughlin said.
The building owner said it was under construction and the workers weren't there yet when the crash happened.
"I would actually like for the city to put up a barrier up [sic] to stop something like this," Beal said.
With the battered semi in front of his driveway, Beal thinks of the driver's family.
"All my prayers go out to them. it's a sad situation to them," he said.
