Two Border Patrol agents found dead early yesterday on the Tohono O'odham Nation had gunshot wounds, and there are no suspects at large, the tribe's police chief said yesterday.

"Since this is an ongoing investigation, the Tohono O'odham Police Department will not have further comment until the investigation is complete," tribal Police Chief Richard Saunders said in a statement.

Saunders confirmed to the Tucson Citizen that the off-duty agents had gunshot wounds and there are no suspects at large.

The agents were stationed in El Paso, Texas, said Doug Mosier, spokesman for the Border Patrol's El Paso sector.

Mosier identified them as supervisory agent Arturo Betancourt, 45, and Border Patrol agent Elizabeth Granillo, 31. Betancourt has been with the agency for 15 years and Granillo for 2 1/2 years, he said. Both worked in El Paso, Mosier said.

The two had relatives in Arizona and El Paso, but Mosier didn't know who had relatives in state.

"But first and foremost, our hearts and prayers go out to the family, friends and colleagues of these agents," he said.

The FBI sent an evidence team to assist tribal police but was not in charge of the investigation, said Susan Herskovits, an FBI spokeswoman.

She referred all further questions to tribal police.

The agents were found in a vehicle in the San Xavier District, about 10 miles southwest of Tucson, at 2:30 a.m. when tribal police responded to a report of an abandoned vehicle, according to a statement from the office of the chairman and vice chairman for the nation.
