The grand jury convened to review Officer Reyes's use of force examined the case for 11 weeks, reviewing all three camera angles, physical evidence from the scene, and testimony from both Reyes and Diane Castellano, who chose to testify in support of the officer who found her. The jury declined to indict, finding the shooting justified given the immediate threat posed by a suspect actively attempting to flee a scene containing an ongoing hostage situation and evidence of a second homicide.

The absence of visual footage of the shot itself which fueled significant public speculation and scrutiny in the weeks after the incident became public was ultimately explained by the reflexive camera movement documented in the department's own technical review. Some community members said that detail complicated public trust in the process regardless of what the footage technically proved. That gap in the footage became for a period of several weeks after the shooting became public the center of considerable local and eventually national attention with some commentators questioning why the one moment that mattered most legally was the one moment no camera fully captured. The department released all three angles publicly alongside a detailed technical breakdown from an independent use of force analyst in an effort to address the speculation directly rather than allow it to compound. The analyst's report concluded that the body camera's angle at the moment of the shot was consistent with known physiological responses officers exhibit when simultaneously monitoring a threat and a victim in close proximity.

Use-of-force researchers have documented that scenario in prior hostage-recovery cases, though rarely under this level of scrutiny.

Community reaction to the case remained divided even after the grand jury's decision. A vigil held for Angela Marchetti drew a large crowd from both her home county and Caldwell County. Several attendees used the occasion to publicly voice support for Reyes, specifically crediting his instinct to investigate an unexplained sound as the reason Diane Castellano survived at all. Others in the community, while not disputing the grand jury's findings, expressed continued discomfort with the fatal outcome in a case where the full sequence of events could not be independently verified through footage. The department's public information officer acknowledged that attention directly, saying the case illustrated both what body cameras can and cannot guarantee and that policy discussions around backup camera redundancy had already begun internally as a direct result.

Officer Reyes returned to active duty four months after the incident following a standard administrative leave and psychological evaluation. In a statement given after the grand jury's decision, he said the hardest part of the entire case for him personally was not the moment he fired his weapon. It was the four seconds before it, standing at that trunk, understanding all at once that the woman in front of him was alive, that the shape beside her almost certainly was not, and that whatever decision he made next was going to be the only thing standing between Diane Castellano going home and her becoming a case file like Angela Marchetti's.

Diane Castellano has spoken publicly on a limited number of occasions since her recovery, most often to advocate for expanded funding for cold case units in rural counties, arguing that Angela Marchetti's disappearance and at least one other case connected to Kessler might have been identified far sooner had different jurisdictions communicated more effectively with each other. She has said, in her own words, that she does not consider herself lucky. She considers herself the person who happened to kick loud enough at the right moment for someone outside that car to hear it.

In the years since, Diane has worked with two separate state task forces reviewing how missing persons cases involving adult women are initially classified and prioritized, drawing directly on her own experience of knowing, from the moment she was first approached at that gas pump, that something was wrong, while investigators in the earliest days of her case were still working through more conventional explanations first. She has said publicly that she does not fault the detectives who worked her case for following standard procedure, but that her experience convinced her the standard procedure itself needs revisiting, particularly around how quickly stranger abduction scenarios are considered when an adult goes missing under circumstances that don't immediately fit a domestic or relationship-based explanation.

She has also spoken, carefully and only in general terms, about the process of returning to ordinary life afterward, describing it as slower and less linear than she expected, and crediting long-term trauma counseling with helping her rebuild a sense of safety and day-to-day routines that once felt unremarkable, and now, for a long time, did not. She has said that Officer Reyes reached out to check on her twice in the year following her recovery, and that both times she found herself reassuring him rather than the other way around. She has described that dynamic as strange, but understandable given what she now knows he carries from those four seconds at the trunk.
