Maricopa County Attorney reviewing criminal cases tied to former Phoenix officers accused in violent traffic stop

The Maricopa County Attorney’s Office is reviewing open and closed criminal cases involving former Phoenix police officers Luis Vasquez Jr. and Antonio Felix, who were arrested August 22 in connection with a violent traffic stop on August 5 in south Phoenix. County Attorney Rachel Mitchell said prosecutors are evaluating how the officers’ involvement in past cases may impact ongoing prosecutions.

The review stems from an alleged violent, unreported traffic stop on Aug. 5, 2026, in south Phoenix, during which a couple was reportedly beaten and repeatedly stunned with a Taser, according to Phoenix police and local media briefings. Former officers Luis Vasquez Jr. and Antonio Felix were fired and arrested on Aug. 22, 2026, in connection with the incident. Arrest documents show each was booked on two counts of aggravated assault, one count of kidnapping, hindering prosecution, tampering with evidence, and making threats. An Aug. 25 complaint from the Maricopa County Attorney’s Office (MCAO) added a second kidnapping charge, a third aggravated assault charge classified as a Class 3 felony, a misdemeanor criminal damage charge against Vasquez, and revised the hindering prosecution charge to conspiracy to hinder prosecution, a Class 5 felony.

County Attorney Rachel Mitchell said during an Aug. 27 media briefing that her office assigned a team with decades of experience to prosecute the current case and review the officers’ past involvement in prosecutions.

She emphasized that prosecutors are evaluating ongoing cases in which Vasquez or Felix were involved to reassess how their participation may affect those cases. Mitchell said prosecutors have been directed to disclose the officers’ arrests and charges to defense attorneys in all relevant ongoing cases and to evaluate each case “in a new light,” which could impact charges, plea offers, or trial strategies.

MCAO’s Prosecution Integrity Unit has been specifically tasked with reviewing closed cases tied to Vasquez and Felix, while the office is also searching its databases for active criminal cases where either officer is listed as a material witness. Officials said the review includes cases where the officers had roles beyond witnesses, such as arresting officers or evidence collectors, which could affect case credibility. MCAO spokespersons confirmed that the number of cases under review has not been publicly quantified and that the potential impact on open cases remains unknown and ongoing.

The officers were booked into Maricopa County jail on Aug. 22 and later released on bail. Their next court date was initially set for Aug. 28, 2026, but a grand jury is expected to deliberate on whether to indict the officers on the charges listed in the complaint. The Aug. 28 hearing could be vacated if an indictment is issued.

Phoenix police officials confirmed that detectives verified the two former officers physically assaulted the couple during the traffic stop and used force, including multiple stun gun applications. The Phoenix Office of Accountability and Transparency (OAT) is also involved, as it is mandated under Phoenix City Code § 20‑6(C) to review department investigations whenever uniformed personnel face allegations of crimes such as assault, kidnapping, or use of force. OAT reports show it managed an active caseload exceeding 140–150 cases in 2025, including use-of-force incidents and criminal allegations, indicating ongoing oversight of police conduct.

MCAO officials said when an officer becomes the subject of an investigation, the office identifies all open cases involving that officer and notifies assigned deputy county attorneys to ensure appropriate disclosures are made to defense counsel, fulfilling ethical obligations. Defense attorneys in affected cases are being notified of the officers’ status, and disclosures about the alleged misconduct may become relevant to motions challenging evidence, witness credibility, or prior verdicts.

Phoenix police and MCAO are coordinating closely to minimize future criminal prosecutions that may be affected by the officers’ alleged misconduct. The review process continues, with prosecutors diligently assessing the specific roles Vasquez and Felix played in every open case where they are identified as witnesses. The scope of potential post-conviction relief or case modifications remains under evaluation.
