A violent brute shot his parents, teen sister and family dog to death – and dragged their corpses to a ravine near his New Mexico house to “bury them,” prosecutors alleged.

Adlai Mestre, 24, was indicted on three counts of first-degree murder and animal cruelty this week for the heinous killings inside his Tijeras home on Oct. 13, 2024, the Bernalillo County District Attorney announced.

Police responded to the grisly scene after reports of gunfire and found Mestre outside his home, clutching a gun and a loaded magazine, court papers obtained by McClatchy News showed.

Mestre was reportedly scrambling to clean up the carnage when cops arrived – also finding a hammer, a blood-stained meat tenderizer, along with gory drag marks and mop streaks on the floor. 

The lifeless bodies of his parents, Bertha Huerta Conde, 51, and Raymundo Mestre, 46, and his 17-year-old sister, Brielle Mestre, were then discovered in a gorge near the scene of the violent massacre, prosecutors said. 

“I killed them and was going to bury them,” Mestre told officers while in custody, court documents showed, the outlet reported. 

The suspect allegedly told police he killed his father in the living room and his mother as she walked down the stairs – but claimed he “didn’t know” what happened to his younger sister, according to the criminal complaint. 

Mestre later kicked and punched a hole through the wall of the interrogation room and briefly escaped before being recaptured, video obtained by KOB4 captured. 

In April, a judge ruled the disturbed man, who has a history of mental illness, was not competent to stand trial, but reversed that decision last month, KRQE reported.  

He was also charged with three counts of tampering with evidence in the triple homicide.
