The family of a U.S. Customs Enforcement agent killed in a 2011 ambush on a Mexican highway and another agent who survived are suing the government and others.
The federal lawsuit filed Tuesday in Brownsville arises from the Feb. 15, 2011, attack on U.S. Immigration and Customs Enforcement agents Jaime Zapata and Victor Avila.
They were attacked in their armored SUV near San Luis Potosi, Mexico.
Zapata died, and Avila was seriously wounded.
The lawsuit names the agents' supervisors among nearly two dozen others. It alleges that Zapata and Avila never should have been sent on the dangerous mission, their armored SUV was flawed and at least two of the guns used in the attack were bought in the United States.
