A traffic stop on a car full of groceries leads authorities to a stash house filled with 45 illegal immigrants.
It all happened off North Stewart Road and Mile 7 and a Half North in Alton around 5:30 p.m. Monday.
Both Border Patrol and Alton police both at the scene.
Investigators told Action 4 News that police officers stopped a car for a traffic violation just down the street.
Officers learned the two inside the car were delivering the groceries inside their car to the stash house.
