Local authorities cooperated with U.S. Border Patrol agents to detain 12 suspected illegal immigrants after a brief high speed chase and bailout Friday afternoon on Highway 77.

They are still searching for at least three more that were able get away.

The chase began just after 1 p.m. Friday at an intersection on Highway 77, just north of Bishop. Nueces County deputies said they noticed a vehicle that didn't stop at an intersection, and they attempted to pull the vehicle over.

After being led on a brief high-speed chase, the vehicle stopped on County Road 18, between Highway 77 and County Road 79. Deputies said at least 15 illegal immigrants bailed out and ran into the brush.

Law enforcement officials said that, when it comes to these types of high-speed chases involving illegal immigrants, it can be dangerous.

"Obviously the danger, first of all, is that these people are not going to stop," said Margarito Gonzalez, Chief Deputy of Precinct 3. "The coyotes are not going to stop. They don't want to get caught. The danger is obviously the traffic. They will do anything they have to do in order to get away."

A total of 12 have been caught and are in the process of being deported. Investigators said the truck is registered out of Houston, and they do not know where it was headed.
