When a trucker stopped at a truck stop at I-37 and Southton Road early today, three men jumped onto his big rig without the trucker's knowledge, News Radio 1200 WOAI reports.
Sheriff's Deputies say after the trucker pulled out onto I-37 one of the men, who had managed to crawl onto the space between the cab and the trailer, began banging on the back window of the cab, trying to get the trucker's attention.
He called 9-1-1, at which time the man fell off the truck onto the highway. He was rushed to SAMMC in critical condition.
The trucker started to pull over as Sheriff's Deputies arrived, and the other two men jumped off the truck and ran away.
They were quickly captured by the deputies.
The men are believed to be illegal immigrants, but Sheriff's investigators are trying to get to the bottom of it.
