Juan Ayala Montero Arrested After Firing Dozens of Rounds at Neighbors

A Memorial Day weekend standoff in Texas ended with the arrest of a twice-deported Mexican national who authorities say fired dozens of rounds at neighbors, wounded a teenager, and barricaded himself inside his home before surrendering to a SWAT team.

Juan Ayala Montero, 60, was taken into custody on May 24 in Montgomery County and charged with felony deadly conduct involving the discharge of a firearm. The arrest followed what investigators described as a dangerous and rapidly escalating incident in the Kings Colony neighborhood.

According to the Montgomery County Sheriff’s Office, deputies responded after receiving reports that Ayala was armed with a long gun and actively firing at multiple people. By the time law enforcement arrived, authorities say he had already discharged numerous rounds throughout the neighborhood.

Faced with a growing police presence, Ayala allegedly retreated into his residence and barricaded himself inside. The standoff continued until the Montgomery County Sheriff’s Office SWAT team arrived and negotiated his surrender. Officials said he was taken into custody without further violence.

Investigators later recovered approximately 31 shell casings from the scene and determined that multiple rounds had been fired toward nearby homes and residents. Witnesses told authorities they attempted to calm the situation and persuade Ayala to put down the weapon, but those efforts were unsuccessful.

Initial emergency calls suggested there were several victims. After reviewing the scene, investigators determined that only one person had been struck by gunfire—a 17-year-old male who was treated at a local hospital and later released.

Authorities say the confrontation stemmed from a dispute between Ayala and the teenager. The investigation took another turn when detectives concluded that the juvenile had provided false information during the inquiry. He was subsequently charged with making a false report to a peace officer after investigators determined his statements hindered the investigation.

Federal immigration officials later revealed that Ayala was also in the United States illegally and is now the subject of both an ICE hold and a federal immigration detainer.

According to Immigration and Customs Enforcement, Ayala is a Mexican citizen who has been deported from the United States twice and has illegally reentered the country multiple times. His criminal history includes convictions for attempted homicide and criminal trespass while living in the United States unlawfully.

Records show an immigration judge ordered Ayala removed from the country in 1999, and he was deported to Mexico in August 2000. Authorities say he later returned illegally and was encountered again by immigration officials following a 2006 arrest by the Dallas Police Department. He was removed to Mexico a second time that same year.

Federal authorities allege that Ayala subsequently entered the United States illegally for a third time before his most recent arrest.

Montgomery County jail records indicate Ayala remains in custody on an $80,000 bond related to the deadly conduct charge. The records also show an active ICE hold and federal detainer.

Federal officials pointed to the case as an example of the value they believe local-federal cooperation provides in identifying and detaining criminal suspects who are in the country illegally.

“The arrest and placement of an immigration detainer on this violent criminal illegal alien is another example of the positive impact that the 287(g) program has on increasing public safety in our local communities,” said ICE Enforcement and Removal Operations Houston Acting Field Office Director Gabriel Martinez.

As the criminal case moves forward, Ayala now faces both state charges stemming from the shooting incident and potential federal immigration proceedings that could once again result in his removal from the United States.
