HOUSTON (KTRK) -- A former Texas Department of Public Safety trooper is facing federal charges after he was arrested for allegedly trying to smuggle illegal immigrants to Houston.



Marvin Davis, 47, was pulled over Thursday along Highway 59 North in Fort Bend County for illegal window tinting. According to federal court documents, Davis told the trooper he worked for DPS.



Court papers state Davis had a vest inside his blacked-out SUVs that read "State Police" and even a mounted laptop computer. The trooper noticed two men in the back seat, and decided to run Davis' plates. The plate information came back to Davis and a state-issued vehicle.



Davis was arrested for impersonating an officer. The two men in the back seat of his SUV were taken into custody and questioned. Court papers state they told federal investigators they crossed into the US illegally.



Court papers state Davis admitted to working with an alien smuggling organization to transport the men from Edinburg and through a border patrol checkpoint in Falfurrias, TX before concluding the voyage to Houston. Investigators said he was paid $500 per person, and said Davis admitted this was his fifth trip.



In 2013, Davis was fired from the Texas Department of Public Safety after he was arrested, charged and convicted of bribery.
