“One of three men arrested and linked with one of the guns used in the murder of a U.S. federal agent in Mexico was part of the U.S. military and received training on weapons.

Ranferi Osorio, 27, spent eight years in the U.S. Marine Corps and served in Iraq and Afghanistan before retiring in 2009, said his ex-wife Valeria Rojas in a statement issued on Wednesday before the federal court case. He supported his family by buying and selling firearms, but had no license or authorization for such trade.

Ranferi Osorio, like his younger brother Otilio, 22, is accused of possessing firearms with altered serial numbers. They were under investigation which took an unexpected turn on Friday 25 February when ATF agents in Dallas were notified that one of the serial numbers of guns used in the murder of Zapata, was related to Otilio Osorio.

Although he had apparently erased the serial number of the gun, it could still be detected on the gun using modern laboratory techniques. The ATF decided to proceed and the three suspects were arrested on Feb. 28 in Lancaster, a suburb south of Dallas.

On 15 February, the ICE agent and his partner Victor Zapata Avila, were shot as they drove along a road in the Mexican state of San Luis Potosi. Zapata died in the attack and Avila was injured.”
