Guadalupe David DeLuna, a 42-year-old Hispanic firefighter with 21 years on the Laredo Fire Department and a U.S. Navy veteran, was shot and killed on April 15, 2020, in Laredo, Texas. The incident followed an alleged break-in at his estranged wife’s apartment, where DeLuna confronted a man identified as 43-year-old U.S. Customs and Border Protection officer Ernesto Gillen. Detectives reported signs of forced entry, a broken door and frame, DeLuna’s body with a gunshot wound to the left upper chest, and a spent .40-caliber casing at the scene.

According to the arrest affidavit, DeLuna had sent threats to his wife before entering and allegedly knocked Gillen to the ground. Gillen, who was charged with murder and released on a $100,000 surety bond, said he shot DeLuna in fear of imminent death; the case was later presented to a grand jury that returned a no bill. DeLuna is remembered by colleagues and family as a devoted father and public servant. Does anyone have information about the events that night or knew DeLuna and can offer further details?
