Mexico City, Jan. 10 — Investigators have not determined why a U.S. citizen, who was arrested and later deported, shot the U.S. vice consul in Guadalajara, the capital of the western Mexican state of Jalisco, last week, Mexico’s Foreign Relations Secretary Luis Videgaray said Tuesday.

“I have no information that allows me to speculate on the motive for this person’s actions,” Videgaray said in an interview with Mexico’s Televisa news station.

In response to a question about whether the shooting was linked to terrorism, the foreign relations secretary said any such conclusion “will be the result of the investigations carried out by the government of the United States.”

The suspected gunman “is an American citizen who attacked another American citizen in a flagrant manner,” was caught in the act by security cameras, and “captured with the very efficient cooperation of state authorities and, especially, the Attorney General’s Office of the Republic,” Videgaray said.

The unidentified suspect shot U.S. Vice Consul Christopher Ashcraft in a Guadalajara shopping center on Friday, Jan. 6, 2017.

Media reports identified the suspect as 31-year-old Zafar Zia; Zia was deported to the U.S. on Monday.

The suspect was detained Sunday in Guadalajara’s Providencia neighborhood by a special response unit and handed over to prosecutors, officials said.

The U.S. government offered a US$20,000 reward for information leading to the suspect’s identification and apprehension.

The consular official is in stable condition and has “responded well to medical treatment,” hospital spokesmen told EFE. – EFE
