Elmer Manzano, the man accused of fatally shooting Houston Police Sgt. Harold Preston during a 2020 apartment call, has been found incompetent to stand trial and will be committed to a state hospital until clinicians decide he can meaningfully participate in his defense. The ruling effectively freezes the capital-murder case that has been pending since Manzano’s arrest on Oct. 20, 2020. Manzano, 57, had been held on federal firearms charges while the state case remained open.
Competency ruling and hospital commitment
According to the Houston Chronicle, doctors for both the defense and the prosecution conducted competency exams in November and December and agreed that Manzano cannot currently assist in his own defense. Rafael Lemaitre, spokesperson for the Harris County District Attorney's Office, told the outlet that "Manzano will be committed to a state hospital until medical officials determine competence." The report also notes a recent Texas Health and Human Services estimate that waits for a maximum-security state hospital bed can range from roughly four to 18 months, meaning the pause in the case could stretch well into the future.
The 2020 shooting and federal charges
The shooting unfolded on Oct. 20, 2020, when officers responded to a domestic-disturbance call at an apartment in the 2600 block of Holly Hall. Sgt. Harold Preston was fatally wounded, and another officer and Manzano's teenage son were injured, according to the City of Houston. Officials there detailed the scene and the capital-murder charge and related counts filed in state court. Weeks later, federal prosecutors charged Manzano with unlawful possession of firearms, as outlined in a press release from the U.S. Attorney's Office, moving him into federal custody on the weapons case.
Federal detention and stalled proceedings
After nearly five years in federal detention on the firearms case, a federal magistrate approved returning Manzano to Harris County custody, the Houston Chronicle reported in 2025. Once he was back in the county system, prosecutors and defense attorneys requested separate psychiatric evaluations. Those evaluations led to this week’s finding that he is not currently competent to stand trial. For now, the state capital-murder prosecution is on hold while treatment, time and bed availability at a secure state facility dictate what happens next.
Mental-health backlog complicates prosecutions
Local officials and advocates have warned that a shortage of secure psychiatric beds and long forensic waitlists routinely slow criminal cases, leaving victims’ families in limbo and courts struggling with packed dockets. Harris County has responded by expanding jail-based competency restoration efforts in an attempt to move cases along. As Houston Public Media reported, some defendants spend many months waiting for a state-hospital placement. A similar competency question surfaced last year in the case of Athir Murady, who has also undergone mental-health evaluations while in custody, according to Click2Houston.
What’s next
Manzano will remain in a state psychiatric facility until clinicians determine he is competent to return to court. Only then would the capital-murder case pick up where it left off. His federal firearms case remains active in federal court, and if the state prosecution resumes, officials will still need to sort out venue questions, potential penalties and whether to pursue the death penalty. For now, the future of the case rests on treatment progress and when a secure hospital bed is available.
