Federal authorities in southern Arizona say smugglers continue to endanger immigrants entering the country illegally by transporting them inside the locked trunks of vehicles.
Customs and Border Protection says it's extremely dangerous for a person to travel in the trunk of a vehicle because of heat, the possibility of an accident or unforeseen circumstances.
CBP says Border Patrol agents found a Guatemalan child locked in the trunk of a car that was stopped after it sped away from a Nogales border crossing on April 16.
Two days later, agents at the Douglas crossing found three immigrants locked in the trunk of a car.
According to federal officials, several of the immigrants said they didn't know about a trunk release mechanism.
