Background
Justin Ashley Flint was convicted in 2007 of first degree murder and attempted robbery after acting as a lookout while Frank Gonzalez attempted to rob off-duty Los Angeles County sheriff's Deputy Maria Cecilia Rosa and shot her. Flint's jury received felony-murder instructions. His original sentence was 29 years to life, but an earlier appeal stayed the attempted-robbery sentence, leaving 26 years to life. Gonzalez was tried separately.
Flint petitioned in 2019 for resentencing under Penal Code section 1172.6 following Senate Bill No. 1437's restrictions on felony-murder liability. Section 189, subdivision (f), preserves the former rule when a peace officer is killed in the course of duty and the defendant knew or reasonably should have known that fact. After the Court of Appeal reversed the initial prima facie denial, the trial court held an evidentiary hearing and again denied relief. A second appeal produced another remand because Flint's new argument concerned whether Rosa's custodial assignments limited her off-duty authority.
At a September 2025 hearing, the prosecution presented personnel, training, and evaluation records and testimony from Investigator Brian Steinwand and Commander Bryan Aguilera. The trial court declined to rely on their classification opinions and instead found from the exhibits that Rosa was a full deputy under section 830.1, subdivision (a). It therefore denied Flint's petition, and he appealed again.
The Court’s Holding
The court interpreted section 830.1, subdivision (c), de novo. Although "employed to perform duties exclusively or initially relating to custodial assignments" could describe either an initial jail assignment or a deliberately limited form of employment, the statutory scheme and legislative history supported the latter reading. The provision applies to deputies hired, trained, and utilized to work exclusively in custody, or initially in custody before completing full training for regular service. The court relied on the contemporaneous reduced-training provisions, the 1996 conference report, and the absence of evidence that the Legislature intended to remove off-duty authority from fully trained deputies merely because they worked in jails.
The court rejected Flint's reliance on individual lawmakers' letters, later legislative digests, a 2002 Attorney General opinion, and training regulations. "Initially" retained meaning for modified deputies who could later complete full POST training. The regulations also distinguished the training needed for general peace-officer authority from additional patrol training. Reviewing the factual finding for substantial evidence rather than reweighing it, the court cited the end of LASD's modified-deputy program before Rosa applied, her full basic training, a job bulletin requiring custody and patrol assignments, and her field rotations. Rosa therefore acted in the course of her peace-officer duties, and the order denying resentencing was affirmed.
On October 29, 2026, the court denied Flint's October 6 rehearing petition and modified its published October 2 opinion without changing the judgment. The amendments expanded the explanation for rejecting the letters and later digests, added a footnote stating that the conference report did not reference the sheriff's letter, deleted a regulatory discussion on page 23, and replaced a sentence in the remaining section 1005 analysis with a narrower statement about plenary peace-officer authority. The court also renumbered subsequent footnotes.
Key Takeaways
- A deputy's initial assignment to jail work does not by itself place the deputy in section 830.1, subdivision (c)'s restricted category.
- The decisive statutory inquiry concerns whether the deputy was hired, trained, and utilized for limited custodial service.
- Substantial evidence supported the finding that Rosa completed regular-deputy training and was not employed under the discontinued modified-deputy program.
- Because Rosa retained off-duty authority and was killed in the course of her duties, Flint remained ineligible for section 1172.6 relief under section 189, subdivision (f).
- The October 29, 2026 order denied rehearing and revised parts of the statutory-analysis discussion while expressly leaving the judgment unchanged.
Why It Matters
The published decision distinguishes limited-authority modified deputies from fully trained regular deputies whose early or continuing assignments are custodial. That distinction directly controls whether the peace-officer exception to Senate Bill No. 1437's felony-murder restrictions defeats a resentencing petition.
The opinion also separates statutory construction, reviewed independently, from the trial court's factual classification findings, reviewed for substantial evidence. Its modification order refined the legislative-history and regulatory reasoning and denied rehearing, but did not alter the affirmance or leave a further issue for decision.
