Monte Alto, TX (KRGV) — The Hidalgo County Sheriff’s Office arrested two 17-year-olds in connection with the Halloween shooting in Monte Alto.

The shooting happened about 11:35 p.m. Oct. 31, 2026, in the 24000 block of Sunflower Lane.

The sheriff’s office said it arrested the two suspects on Thursday, Nov. 12, and were identified as Dilan Cole Suarez and Lizzet Gallegos.

Suraez and Gallegos were arraigned on Friday, Nov. 13 on a charge of aggravated assault — mass shooting. Their bonds were set at $1 million each.

Witnesses told investigators someone in a light colored SUV fired a weapon as the vehicle drove away from the area. Nine people suffered injuries that were not life threatening; they have all since been released from the hospital.

Investigators recovered surveillance footage from the scene and identified four people of interest. One of those people was identified as Suarez, who later identified the other three suspects, including Gallegos.

Witnesses provided statements identifying Suarez as the shooter and that Gallegos instructed him to shoot.

A search warrant was executed on the suspect vehicle where investigators found spent casings of the same caliber as those found at the scene.

Investigators also recovered a firearm from Suraez's father's home. A test fire showed the casings from that gun matched the casings from the crime scene.

The sheriff’s office said the gathering was a pay to enter party for teenagers and young adults. Investigators are still following leads tied to who organized the party and said those organizers will also face criminal charges.

The sheriff’s office said the Texas Rangers, U.S. Border Patrol and the Edinburg CISD Police Department helped with the investigation.
