Brothers beat step-father to death for abusing 9-year-old sister

The three, all aged 18 years, are being held in Hidalgo County Jail in connection with the death of Gabriel Quintanilla, 42 years of age, who was beaten and left to die of his wounds in a field in McAllen Texas. His body was later discovered by a local farmer with evidence of "severe blunt force trauma to his head."

According to local outlet KSAT, "police reported that a minor, later identified as Quintanilla’s daughter, made an outcry about being inappropriately touched by Quintanilla at an RV park."

The police in Pharr Texas, where all four individuals reside/resided, released a statement which said:

"When brothers [Alejandro] and Christian Trevino found out, they became enraged and confronted Gabriel Quintanilla at the residence. A physical fight ensued between the three and the victim Quintanilla left the location on foot."

Police also report that Quintanilla had a warrant for family violence and continuous sexual abuse of a child at the time of his demise.

Melendez then drove Alejandro Trevino to a nearby location while Christian Trevino followed Quintanilla on foot. They caught up to him and attacked him a second time. They then changed vehicles, found Quintanilla again and assaulted him a third time.

The now-deceased Quintanilla was now placed in the bed of a truck and taken to the field, where he was dumped. Police are currently investigating whether he was still alive at the time they disposed of him.

The trio are charged with aggravated assault and organized criminal activity. Melendez and Christian Trevino have also been charged with murder, and Melendez with possession of marijuana.
