Fairfield police say a knife-wielding theft call on the 1800 block of North Texas Street ended with officers tracking down a suspect inside a nearby business and taking him into custody without further incident. The department identified the arrested man as 26-year-old Mathew Gernux and said he faces robbery and assault-with-a-deadly-weapon allegations.

What the Department Says

According to the Fairfield Police Department on Facebook, officers were dispatched last Tuesday after reports of a suspect armed with a knife stealing from a business in the 1800 block of N. Texas Street. The post states officers went inside the business, detained the suspect there and arrested him at the scene.

How Technology Helped Officers

The department says its Real-Time Intelligence Center pulled up an overhead view of the area using city CCTV cameras along North Texas Street, which helped officers locate the suspect. In the Facebook post, the department wrote that "the integration of real-time intelligence remains a vital resource for officers to locate suspects quickly and resolve potentially dangerous situations more safely."

Context: Surveillance Tools in Past Cases

Fairfield has also leaned on camera and license-plate technologies in earlier investigations. In December, authorities credited automated license-plate readers and county camera feeds for helping track a suspect during a multi-agency response, as reported by Hoodline. Those systems have also drawn scrutiny from civil liberties groups, according to SFGATE, but local officials say they help end volatile situations more quickly and safely.

Legal Implications

Gernux was arrested on suspicion of robbery and assault with a deadly weapon, according to the department's post. Robbery is defined under Penal Code 211, and assault with a deadly weapon is codified at Penal Code 245. Both are felony offenses, with penalties that depend on the specific counts and enhancements prosecutors ultimately file.

What to Expect Next

The Fairfield Police Department's Facebook post remains the primary public account of the arrest and does not list booking details or a court date. Official booking records and any filings from the Solano County District Attorney's Office will spell out formal charges and the next steps in the case as it moves through the court system.
