The California Court of Appeal has upheld the murder conviction of Justin Ashley Flint, affirming that he played a role in the fatal shooting of an off-duty sheriff's deputy. The ruling, issued on October 2, 2026, affects Flint, who has been seeking resentencing under a law that allows certain defendants to challenge their murder convictions based on changes in the law.

Flint was convicted in 2007 for his involvement in the murder of Deputy Maria Cecilia Rosa, who was killed during a robbery attempt. The court's decision is significant as it clarifies the application of California's felony-murder rule, particularly in cases involving peace officers.

Background

The case stems from a 2006 incident in which Flint acted as a lookout while his associate, Frank Gonzalez, attempted to rob Deputy Rosa, who was off-duty at the time. During the robbery, Gonzalez shot and killed Rosa. Both Flint and Gonzalez were charged with first-degree murder and attempted robbery. In 2007, a jury convicted Flint on both counts.

In 2019, Flint filed a petition for resentencing under California Penal Code section 1172.6, which allows defendants convicted under certain homicide theories to seek relief if the law changes. This section, however, does not apply if the victim is a peace officer killed while performing their duties, and if the defendant knew or should have known the victim was a peace officer. The trial court found that Rosa was acting in her capacity as a peace officer when she was killed, leading to the denial of Flint's petition.

The Ruling

The California Court of Appeal, in its ruling, affirmed the trial court's decision. The court concluded that substantial evidence supported the finding that Rosa was acting in the course of her peace officer duties at the time of her death. The ruling stated, "Rosa was a full peace officer conferred with the authority to effectuate an arrest outside of a custodial setting when Gonzalez shot her, and Flint is not entitled to section 1172.6 relief." The judges involved in this decision were not specified in the court filing.

Flint's argument centered on the interpretation of section 830.1, subdivision (c), which outlines the authority of deputy sheriffs. He contended that Rosa lacked peace officer authority while off duty because she was primarily assigned to custodial duties. However, the court disagreed, stating that section 830.1, subdivision (c) applies only to deputies specifically hired for limited custodial roles, not to those like Rosa who were fully trained as peace officers.

Impact

This ruling has significant implications for Flint and others in similar situations. It clarifies the legal interpretation of peace officer authority in California, particularly regarding the felony-murder rule and the rights of defendants seeking resentencing under the new law. The court's decision reinforces that if a victim is a peace officer killed while on duty, defendants cannot claim relief under section 1172.6, even if the officer was off-duty at the time of the incident.

The ruling also emphasizes the importance of understanding the specific circumstances surrounding a peace officer's duties and the implications of their status at the time of an incident. This case may set a precedent for future cases involving the felony-murder rule and the status of law enforcement officers in California.

What's Next

Flint has the option to appeal the ruling to a higher court, but it remains unclear if he will pursue that route. The court filing did not indicate any related cases pending that could affect Flint's situation.
