“We have lost two brave public servants who sought only to keep peace in our City,” McAllen police Chief Victor Rodriguez said via text message Saturday, according to the newspaper.

The two police officers  killed Saturday in what authorities described as an ambush shooting were identified as Edelmiro Garza, 45, and Ismael Chavez, 39. They were killed while responding to a domestic disturbance complaint.

The gunman, Audon Ignacio Camarillo, 23, took his own life after fatally shooting two police officers, authorities say. The suspect was most recently arrested last month on assault charges.

Texas Governor Gregg Abbott addressed the news via Twitter on Saturday evening and praised the self-sacrifice of the two officers. “Two of our finest were killed in the line of duty while working to protect residents in their community,” Abbott wrote. “I’ve spoken with McAllen Police Chief Victor Rodriguez and offered the full support of the State of Texas. We unite to #BackTheBlue.”

“Our prayers and full support are with the valiant men and women of the #CityofMcAllen PD this evening,” the message read. “This office will provide any assistance requested in the days ahead. We are grateful for police in McAllen and around this great state.”
