A San Antonio man, 34-year-old Luiz Armondo Diaz Mendez, is behind bars after police allege he threatened to kill multiple people at a local neighborhood pub, even bringing flowers days before the date he purportedly intended to strike.
According to the San Antonio Police Department and the arrest report viewed by local news outlet KSAT, the incident began in the early morning hours of New Year’s Eve, 2025, at The Ringer Pub, located on Thousand Oaks Drive in San Antonio. That night, Diaz Mendez was allegedly causing a disturbance inside the bar just before 1 a.m., and staff escorted him out and banned him from the establishment.

More than 12 hours later, around 1:30 p.m. on New Year’s Day, surveillance footage showed Diaz Mendez returning to the pub carrying a bouquet of flowers, which police now say hinted at a chilling plan rather than a peace offering for what happened the night before.
According to reports, once inside the establishment, Diaz Mendez approached an employee near the bar area, set down the flowers, and said, “These are for you,” the affidavit states. He then asked about a black iPhone he had left behind during the earlier incident. Staff retrieved the phone and instructed him to leave the premises, but the encounter escalated.
Diaz Mendez then allegedly asked the employee, “You don’t work Tuesdays, do you?” and “Stay away from it. Stay away from next Tuesday night,” a reference authorities say pointed to a potential future act of violence.
When the employee reiterated that Diaz Mendez should leave and stay away from the location, police say he became infuriated, picked up the bouquet, and threw it back onto the bar. That’s when he allegedly said, “Those are flowers for the people about to get murdered.”
The 911 call
The employee called 911 out of fear for her safety and that of her co-workers and officers responded. Investigators later showed her a photograph lineup; she identified Diaz Mendez as the man from the video, and the bar’s surveillance footage corroborated her account, authorities said.
On Saturday, following the incident, San Antonio police arrested Diaz Mendez and booked him into the Bexar County Adult Detention Center. He was officially charged with making a terroristic threat, a serious offense under Texas law involving credible threats of violence intended to alarm the public or disrupt public safety.
The charge is classified as a third-degree felony, which under Texas statutes can carry 2 to 10 years in prison and fines up to $10,000, although sentencing depends on court proceedings and conviction.
A Bexar County judge set bond at $30,000. As of the latest available public records, Diaz Mendez remains in custody at the Bexar County Adult Detention Center, with bond conditions stipulating that if he were to post bond, he would be placed on house arrest pending future court dates.
