Texas State Troopers arrested 24-year-old Gilbert-Joseph Darshan Dennis Mershac on Saturday in Brooks County.
Troopers said they stopped for what appeared to be a stranded motorist parked on the northbound shoulder of SH 281. That's when they found the four passengers were illegal immigrants. Troopers believe Mershac had stopped to pick up the four passengers and was waiting on more to arrive when the authorities showed up.
The 24-year-old was arrested on human smuggling charges.
