(CNSNews.com) - "Border Patrol Officer killed at Southern Border, another badly hurt," President Trump tweeted on Sunday. "We will seek out and bring to justice those responsible. We will, and must, build the Wall!"
According to the U.S. Customs and Border Protection Agency, Agent Rogelio Martinez was "responding to activity" near Interstate 10 in the Big Bend Sector of Texas when he and his partner were attacked.
The circumstances are unclear. According to CBP, agents from CBP's Air and Marine Operations searched the area "for potential suspects or witnesses."
Martinez' partner is now hospitalized in serious condition, but he was able to call for help.
Elaine Duke, the acting Homeland Security secretary, issued a statement saying:
Earlier this morning, I was notified that Border Patrol Agent Rogelio Martinez died as a result of serious injuries suffered while on patrol in the Big Bend Sector of our southern border in Texas.
Agent Martinez was responding to activity while on patrol with another agent, who was also seriously injured. We are fully supporting the ongoing investigation to determine the cause of this tragic event.
On behalf of the quarter of a million frontline officers and agents of DHS, my thoughts and prayers go out to the family and friends of Agent Martinez and to the agent who is in serious condition.
CBP said the Culberson County Sheriff’s Department, Federal Bureau of Investigation, Office of Inspector General, and CBP’s Office of Professional Responsibility are investigating.
