West Virginia Regional Jail & Correctional Facility Authority Smoke awoke Delgado’s husband, who tried to save their sons but was unable to do so because of the flames. Delgado’s husband survived the fire. Delgado’s father, Drew McCombs, who lives across the street, heard his son-in-law crying for help from a kitchen window and opened the trailer door, which had been secured from the outside, the criminal complaint alleges. According to reports, McCombs tried to save his grandsons, but the heavy smoke made it impossible for him to find the boys. “I got in there and I couldn’t see, I couldn’t see nothing — at all,” McCombs told the Associated Press. “I couldn’t find them.” Delmer and Justin Delgado were pronounced dead at the scene. • Pick up PEOPLE’s special edition True Crime Stories: Cases That Shocked America, on sale now, for the latest on Casey Anthony, JonBenét Ramsey and more.
