The New York TimesMEXICO CITY — The gunmen who attacked two American law enforcement officials in Mexico on Tuesday, killing one and wounding the other, knew they were firing on foreign officers but proceeded anyway, current and former American officials said Wednesday.
But an important unresolved question is whether the Immigration and Customs Enforcement agents were attacked because of their work — more than one Mexican drug gang has expressed interest in killing American officers — or for another reason, like an attempt to steal their dark and presumably armored S.U.V., a vehicle favored by drug gangs.
The Justice and Homeland Security Departments announced on Wednesday the creation of a task force to work with Mexican federal authorities to investigate the shooting, which killed Jaime Zapata and wounded his colleague, Victor Avila. Mr. Zatapa was the first American immigration agent to be killed in Mexico.
The men were shot as they traveled in their vehicle, which had diplomatic plates, on a main highway to Mexico City from San Luis Potosí, about 265 miles to the north. Mr. Avila was released from an American hospital on Wednesday after being treated for gunshot wounds to his legs.
