Yesterday at approximately 1650 hours, while conducting a routine patrol at a property currently serviced by our company, Captain W. Mills was making contact with several homeless individuals in a stairwell near the leasing office. Captain Mills made contact with two repeat offenders and detained one suspect in handcuffs for criminal trespassing while preparing to contact law enforcement.

The second repeat offender, identified as Geraldo Valencia, refused to comply with verbal commands to come down the stairs and leave the property. Geraldo Valencia then suddenly fled on foot. Captain Mills did not pursue the suspect as he ran from the area.

Captain Mills observed Geraldo Valencia running eastbound on the second-floor walkway. Moments later, a loud banging noise was heard followed by a person screaming. Shortly afterward, Captain Mills observed the suspect running back toward him with a large laceration on his right forearm. Captain Mills immediately noticed that the suspect was bleeding heavily, with blood actively squirting from the wound.

Based on observations made on scene, the suspect appeared to have attempted to jump from the second-floor walkway in an effort to clear the wrought iron perimeter gate. The suspect did not successfully clear the gate and instead impaled his right forearm on a pointed hook attached to the perimeter fence, causing the severe laceration.

Captain Mills immediately radioed dispatch requesting emergency medical assistance and advised that 911 was needed immediately. He then applied a tourniquet above the wound on the suspect’s right upper arm in an attempt to control the bleeding. The tourniquet was tightened, secured, and marked with an application time of 1700 hours. The suspect was instructed to remain seated while awaiting the arrival of medical personnel.

At approximately 1710 hours, Captain Mills observed the bleeding beginning to increase again. He tightened the tourniquet further in order to fully restrict circulation to the injured area. The bleeding was successfully controlled after the adjustment.

Emergency medical personnel arrived on scene at approximately 1715 hours. Medical personnel advised that the prompt application of the tourniquet likely prevented the suspect from losing a significant amount of blood. The suspect was subsequently transported to the hospital for further medical treatment.

Incident report
Trespass notice
Reference number #2603300113255555

On 03/29/26 while conducting routine patrols at approximately 1621 hours, I, CPT Mills, performed a thorough walk-through of the property. Upon approaching the leasing office corner, I observed a male subject in the middle hallway near the staircase. The subject was holding a piece of tinfoil, had a straw in his mouth, and was using a lighter and/or torch to smoke what appeared to be fentanyl on private property.

I made contact with the subject in order to gather necessary information for documentation. During the contact, the subject attempted to walk around me and flee. I informed the subject that he was not free to leave until I obtained the required information. The subject then complied.

I was able to obtain and document the subject’s first and last name, date of birth, and a photo of his face for identification purposes. I advised the subject that he is officially trespassed from both properties serviced for this client and is not permitted to enter or remain on the premises.

The subject was further informed that if he returns to the property, he may be detained for criminal trespassing and local law enforcement will be contacted,

Here’s an uncomfortable truth about the security industry:

A lot of companies selling “security” are really just selling bodies in uniforms.

They show up for the contract signing, place a guard on site, and disappear. No site visit. No risk assessment. No real strategy. Just a warm body standing at a post.

Many clients don’t realize the problem until something goes wrong.

Professional security companies operate very differently.

A legitimate security provider insists on seeing your location. They walk the property, observe operations, ask about the challenges you’re facing, and work with you to build a security strategy that actually reduces risk.

They care about officer performance.
They care about attendance.
They care about whether the security plan actually works.

Because effective security is not about filling a shift — it’s about solving problems.

If the security company you’re hiring never asks to visit your site, never asks about your vulnerabilities, and never discusses strategy, you’re probably not getting security.

You’re getting a uniform.

Organizations should expect more from the companies responsible for protecting their people, property, and reputation.

Good afternoon Arizona clients and residents,

We would like to give a big thank you to Tucson Crime Free for taking the time to interview our team following the recent shooting incident. We chose to work with your platform to help share what truly happened and bring awareness to the situation.

At Treestone Security Services, we take pride in going above and beyond for every client and every property we are trusted to protect. While security professionals don’t always receive recognition from the news or even local law enforcement, we remain committed to doing our job to the best of our ability and keeping our communities safe.

Thank you to our clients and residents for continuing to trust us to serve and protect your properties.

Good morning, Arizona residence and clients,

As many of you may know, Lieutenant Michael Gomez was previously an employee here at Treestone Security Services. Security can be an excellent stepping stone toward advancing a career in law enforcement or the military, and Michael is a great example of that path.

As of yesterday, I was informed that Michael has officially graduated and advanced in his military career. This is a major accomplishment, and we are proud to see one of our former team members continue to grow and succeed.

On behalf of Treestone Security Services, I want to personally congratulate him and wish him continued success in his military career and future endeavors.

We are not like most security companies in the Tucson, Arizona and surrounding areas. Our company is growing every day because of the trust and satisfaction of our customers, clients, and residents. Above all, our mission is simple: to make our community safer—one step at a time.

While many companies operate strictly under the traditional “observe and report” model, we take a proactive approach. We believe in professional, responsible action—combined with the fundamentals of observe and report when appropriate.

Whether we are conducting patrols or working a standing post, we take our responsibilities seriously. Our priority is safety, visibility, and crime prevention. When criminal activity occurs, we investigate within our authority, remove trespassers or violators when legally permitted, and immediately report issues to property management or law enforcement so swift action can be taken.

If one of our officers is assaulted or threatened, we will respond professionally and within the law. We will detain suspects when legally justified and contact local law enforcement to ensure accountability. We stand together as a team—when one of us is targeted, we support one another fully and work diligently to provide law enforcement with the information necessary to identify and hold the responsible party accountable.

We are committed.
We are proactive.
We are united.
And we are here to protect what matters most.
