Deputies arrest triggerman in Brownsville shooting

Suspect: Clarisa Laila Maldonado

Authorities have arrested a Brownsville teenager accused of shooting a man in the head.

U.S. Customs and Border Protection (CBP) officers arrested 18-year-old Gerardo Montejano around 9 p.m. Tuesday.

CBP officials reported that Montejano was a passenger in a white 1992 Ford Explorer that arrived from Matamoros at Brownsville's Veterans International Bridge.

A records check revealed that the Brownsville teen was wanted on engaging in organized criminal activity, aggravated assault and tampering with evidence charges.

Deputies booked Montejano into the Cameron County Jail early Wednesday morning.

The Crime

Investigators believe Montejano pulled out a gun and shot 35-year-old Roman Garcia in the head.

The incident happened in broad daylight at the El Jardin Superette gas station off FM 802.

The shooting prompted officials to put nearby Rivera High School and Vermillion Elementary School under lockdown.

Deputies arrested Clarisa Laila Maldonado, Jason Edward Crawford and Roberto Ramos, Jr. for their roles in the crime on Tuesday.

Father Turns In Son

Cameron County Sheriff Omar Lucio told Action 4 News that Montejano fled to his father's home in Matamoros.

Investigators told Gerardo Montejano, Sr. that he could face hindering apprehension charges in the United States.

The Matamoros man drove his son to the Veterans International Bridge and turned him over to authorities.

Sheriff Lucio said that Montejano had planned to shoot Garcia, who is a U.S. Navy veteran.

Garcia remains in critical condition at the Brooke Army Medical Center in San Antonio.

Sheriff Lucio said the investigation continues but charges against Montejano may be upgraded to attempted murder.

If Garcia dies, Montejano could face a capital murder charge.
