A Border Patrol agent was laid to rest Saturday following his mysterious death  at the bottom of a culvert in the Texas desert.
Family, friends and law enforcement officers attended the funeral at a Catholic church in El Paso, Texas, to mourn the death of Rogelio Martinez, 36, the Washington Post reports .
Martinez’s U.S. flag-draped coffin was carried by Border Patrol pallbearers in green uniforms while bagpipes played.
“It honors him to see law enforcement agencies from across the United States” attend the service, Border Patrol spokesman Ramiro Cordero told reporters outside the church.
Martinez, who was responding to a triggered sensor on Sunday night in west Texas, was found with “traumatic head injuries” and broken bones. He died early Sunday from head injuries.
His partner, who has not been identified, also was found with head injuries and had been in critical condition last week.
The union representing Border Patrol officers insist the agents were attacked with rocks, but the FBI is not so sure.
