Border Patrol agents are seeing a spike in the number of people hiding in vehicles trying to sneak through highway checkpoints.
“It something that we see that’s very dangerous,” said Yesenia Lopez, a U.S. Border Patrol agent in the El Paso area.
People are crammed into hidden compartments, stashed in trunks, or loaded like cargo into 18-wheelers by smugglers trying to get past highway checkpoints.
