The bodies found yesterday in Mexico, apparently including that of a missing Drug Enforcement Administration agent, "had been subjected to physical violence," Acting DEA Administrator Jack Lawn said last night.

Lawn quoted a medical examiner in Mexico as saying the two had broken bones and one had a gash across his head that could have been the cause of death.

No bullet wounds were reported, Lawn said at a press conference. The bodies thought to be those of Enrique Camarena Salazar and a Mexican pilot were wrapped in plastic and "dumped on a roadside," he said. The pilot had flown missions for DEA.

The bodies, which were decomposed, previously had been buried at another location and exhumed, according to a DEA source.

The bodies were discovered on a roadside near Zamora by Mexican federal police, who were acting on a tip, Lawn said. Lawn added that he is in "regular contact" with the State Department, Attorney General Edwin Meese and the White House about the incident.

Camarena, 37, a Mexican-born naturalized American with nearly 11 years' experience at the DEA, was abducted Feb. 7 as he left his Guadalajara office to have lunch with his wife. An eyewitness told DEA investigators that Camarena was grabbed by four armed men and thrown face down into a car. The pilot was abducted the same day in a different section of the city.
