A pair of Texas teen brothers have been charged with murder along with a friend after they allegedly, beat their stepdad to death with brass knuckles over claims he molested their nine year-old half-sister.  
Christian Treviño, 17, and Alejandro Treviño, 18, were arrested by the Pharr Police Department on Saturday for the brutal killing of Gabriel Quintanilla.
Quintanilla, 42, was beaten to death last Thursday.
Authorities also apprehended their friend, Juan Eduardo Melendez, also 18, who helped the brothers attack the father of their half-sister.
The Treviño brothers, Alejandro and Christian, have the same father but different mothers. Both are half-siblings of the alleged 9-year-old victim.
The Pharr Police Department said Quintanilla was beaten with brass knuckles and thrown into the flatbed of a pickup truck before the defendants abandoned his body in a McAllen field.
Cops say Quintanilla who suffered head trauma may have been alive when the brothers and their accomplice dumped his body.

The third defendant, Juan Melendez is accused of aiding the Treviño brothers in the savage beating of the boys’ stepfather, Gabriel Quintanilla, who was accused of sexually assaulting their nine-year-old half-sister.
Melendez was charged charged with capital murder, aggravated assault and engaging in organized criminal activity.

The Pharr Police Department responded to a 911 call on Thursday afternoon from a farmer who said that he’d discovered the body of a deceased male in one of his fields.
Investigators responding to the scene identified the victim as Quintanilla, who had a warrant out for continuous sexual abuse of a child and assault, according to MYRGV.

The incident unfolded when the Treviño brothers went looking for Quintanilla at a RV park residence after they had learned that he had allegedly inappropriately touched their sibling.
The Pharr police said a fight ensued between the three men before Quintanilla took off running. Authorities say Christian Treviño ran after Quintanilla and cornered him in an apartment complex. Alejandro Treviño was joined by Melendez in the second beating of Quintanilla.

The three teenagers left the scene of the assault to changed their vehicles and later went back to look for Quintanilla, who was spotted walking down a road.
The Treviño brothers and Melendez then attacked Quintanilla for a third time and placed his body in the pickup truck.
Christian and Melendez face capital murder charges, and all three face aggravated assault and engaging in criminal activity charges.  

Alejandro Treviño was charged with aggravated assault and engaging in organized criminal activity.
Pharr deputy police chief Juan Gonzalez said capital murder charges were not filed against Alejandro Treviño because Christian Treviño and Melendez were the ones who delivered the blows that eventually killed Quintanilla.
Pharr police chief Andy Harvey explained that the case had rose to the level of capital murder charges due to Quintanilla’s kidnapping, in which police say the victim was put in the back of a pickup truck and dropped off at another location, and that the brothers stole some property from Quintanilla.
The Treviño brothers and Melendez remain jailed on bonds ranging from $1 million to over $1.5 million.
Pharr police chief Andy Harvey revealed during a press conference Tuesday that Quintanilla had a 2019 arrest warrant for allegedly sexually abusing another minor.
Quintanilla had sexually assaulted the girl between 2014 and 2016.
‘He was being elusive, obviously hiding from us,’ Harvey said.
Some activists have started a drive to collect signatures appealing to the Texas Governor for the release of the Treviño brothers. The drive on change.org has collected 191,774 signatures of the 200,000 target so far.
The petition drive started by Carlos Eduardo Espina states: “he three teenagers are currently in custody and have their bonds set at over 1 million dollars each. If convicted of capital murder, they face a minimum sentence of life imprisonment without parole.
“We ask that the state of Texas to release these teenagers, who could possibly spend the rest of their life in prison for protecting their sister.”
