Deputy Shot Dead While Working Security at Austin Nightclub

Tragic End to Young Career

A Caldwell County deputy was shot and killed while working security at an Austin nightclub early Sunday morning, cutting short a law enforcement career that had just begun three months ago. Aaron Armstrong, who had been with the Caldwell County Precinct 3 Constable's Office since October 9, 2024 , was found in the parking lot of Club Rodeo with fatal injuries just after 2 a.m.

The Caldwell County Constable's Office confirmed that Armstrong was working a security position at the establishment when the shooting occurred. Prior to joining the constable's office, he served with the Smithville Police Department from 2011 until 2015 , bringing years of experience to his new role before his life was tragically cut short.

The incident marks a disturbing pattern of violence at the North Austin venue. Armstrong had previously been involved in an altercation at the same nightclub on Black Friday, November 28, when he was taken to the hospital but later reported to be in stable condition . This time, there would be no recovery.

Swift Law Enforcement Response

When officers arrived at Club Rodeo on North Lamar Boulevard, they found Armstrong in the parking lot with trauma to his body. He was rushed to the hospital where he died . The quick response couldn't save the deputy's life, but it set the stage for an intensive manhunt.

A suspect was apprehended by the U.S. Marshals Lone Star Fugitive Task Force with assistance from APD Air Support, K9, and the Texas Department of Public Safety at 3:45 p.m. Sunday . The coordinated effort involving multiple agencies demonstrates the serious commitment to bringing the shooter to justice within hours of the crime.

Community Safety Concerns

Local business owners and vendors have raised alarm about deteriorating safety conditions around Club Rodeo. "I done rode through after they closed, and I could sometimes see guys fighting. I also heard gunshots. On Sundays over here, I know it's safe because it's daytime, but other than that, I don't come out too much at night because it's a bad area," says Easy, who trades at the local flea market .

"There's been a nightclub here for over 30 years, different nightclubs, rock, country. Just recently it's what's been happening here. It's this area, they need to redo this whole area," says another local business owner . These concerns reflect broader questions about nightlife security and the dangers faced by off-duty officers working private security jobs.

Investigation Continues

Detectives specifically requested that the public review cell phone or social media videos and photos that may have captured the moments leading up to, during or after the incident . A reward of up to $1,000 may be available for any information that leads to an arrest , though a suspect is already in custody.

The loss of Armstrong represents more than just another crime statistic. It highlights the vulnerability of law enforcement officers who take on additional security work to supplement their income, often placing themselves in harm's way even when off duty. As Austin police prepare for a news conference Monday afternoon, the investigation will likely focus on what led to this deadly encounter and whether better security measures could prevent similar tragedies in the future.
