Background and Circumstances of the Disappearance

Who Was Patrick Matthew Reano?

Patrick Matthew Reano was born on September 26, 1972. He was 36 years old when he was last seen in Antioch, a city in eastern Contra Costa County in California’s San Francisco Bay Area.

According to the California Department of Justice, Reano is a white male with brown hair and brown eyes. At the time of his disappearance, he was listed as approximately 6 feet tall and weighing 220 pounds. These physical characteristics remain important identifiers for anyone reviewing historical sightings or information about unidentified individuals.

Publicly accessible official records provide little additional biographical information about Reano. Reliable details about his occupation, family relationships, daily routines, and personal circumstances before his disappearance have not been established in the sources reviewed. Rather than speculate about his private life, the documented facts offer the clearest foundation for understanding his case.

May 21, 2009: The Last Known Sighting

May 21, 2009, is the official date Reano was last seen. Antioch, California, is identified as his last known location.

The publicly available case record does not identify a precise street address, building, or other specific location where he was last observed. It also does not establish the time of the sighting, who last saw him, what he was wearing, or where he intended to go.

These missing details are significant because they limit the publicly documented timeline. Without a confirmed account of his final activities, it is difficult to determine where his movements may have taken him or whether an unusual event occurred before he disappeared.

A Disappearance With Few Public Details

Reano has not been publicly documented as located in the official missing-person information reviewed for this article. His case remains listed through California’s missing-person information system, with the Antioch Police Department identified as the reporting agency.

Although online discussions have raised questions about the circumstances of his disappearance, such discussions should not be mistaken for verified investigative findings. No publicly confirmed explanation establishes why Reano vanished or what happened to him after May 21, 2009.


Investigation History and Evidence

The Antioch Police Department Investigation

The Antioch Police Department is the law enforcement agency identified by the California Department of Justice as responsible for Reano’s missing-person case. The state’s official listing identifies the police case number as A10-1684.

The available public record confirms the existence of the missing-person report but provides little detail about investigative activity. Specific search operations, interviews, surveillance reviews, or investigative findings have not been independently verified through the sources reviewed.

The police reference number begins with the characters A10, but this does not independently establish when the report was filed or when particular investigative steps occurred. The confirmed disappearance date remains May 21, 2009.

State and National Missing-Person Records

Reano’s identifying information appears in the California Department of Justice missing-person database. Secondary missing-person listings also associate his disappearance with National Missing and Unidentified Persons System reference MP84049.

These records help preserve essential details, including his name, physical description, disappearance date, and last known city. Maintaining accurate identifying information is particularly important in older cases, when the original disappearance may have received limited publicity.

Physical and Forensic Evidence

No publicly verified inventory of physical evidence connected to Reano’s disappearance was located. The reviewed sources do not establish whether investigators recovered personal belongings, obtained surveillance footage, examined a vehicle, or collected forensic material associated with his last known movements.

The California Department of Justice record indicates that dental X-rays were not available in the information published for his case. This does not establish whether other medical or identification records exist outside the public listing.

No confirmed public announcement was located describing DNA identification, investigative genetic genealogy, a forensic match, or the identification of remains belonging to Reano.

Suspects, Arrests, and Criminal Proceedings

The publicly available sources reviewed do not identify an officially named suspect or person of interest in Reano’s disappearance. No verified arrest, criminal charge, or court proceeding directly connected to the case was located.

This absence of publicly confirmed information does not prove that investigators have no leads or have taken no investigative steps. It means that such details cannot be responsibly presented as established facts without additional official documentation.


Theories and Unresolved Questions

What Happened After May 21, 2009?

The central unresolved question is what happened to Patrick Reano after his last reported sighting in Antioch. Public records do not establish whether he left the area voluntarily, experienced an accident or medical emergency, encountered another person, or became the victim of a crime.

These possibilities are general questions that can arise in missing-person investigations, not verified theories attributed to the Antioch Police Department. There is insufficient publicly confirmed evidence to identify any one explanation as more likely than the others.

Was Foul Play Involved?

Some secondary missing-person descriptions characterize Reano’s disappearance as suspicious. However, the California Department of Justice identifies him as a missing person, and the public records reviewed do not establish a homicide determination.

Without verified forensic evidence, an official investigative conclusion, or documented criminal proceedings, it would be inappropriate to describe his disappearance as a confirmed murder.

Unanswered Questions About His Final Movements

Several important questions remain unresolved in the public record. Where exactly was Reano last seen? Who had contact with him that day? Was he traveling on foot or using transportation? Did he have a known destination? Were any personal belongings recovered after he disappeared?

Answers to these questions could help establish a more complete account of his final known movements. At present, however, the reviewed sources do not provide sufficient evidence to answer them.

Separating Online Speculation From Evidence

Community discussions can help maintain public awareness of an unresolved disappearance. However, personal recollections, anonymous comments, and speculation about possible locations or causes of death are not substitutes for verified investigative findings.

No unverified allegation about Reano’s lifestyle, possible associations, or presumed fate should be treated as an established explanation for his disappearance. Any potentially relevant firsthand information is best provided directly to investigators, who can assess it against evidence that may not be publicly available.


Latest Publicly Available Investigative Updates

Case Status as of October 2026

As of the October 31, 2026 research review, Patrick Matthew Reano continued to appear in publicly accessible missing-person records, including the California Department of Justice listing identifying the Antioch Police Department as the reporting agency.

No publicly confirmed recent investigative breakthrough was located. The reviewed sources did not establish a recovery, positive identification of remains, arrest, criminal prosecution, or official resolution of his disappearance.

The continued availability of a missing-person profile should not be interpreted as evidence of a newly reopened investigation or a recent discovery. Likewise, newer online discussions and redistributed case information do not independently establish a change in the investigation’s status.

Potential for New Information

Although many years have passed, information about Reano’s whereabouts on or around May 21, 2009, could still be relevant. A previously unreported conversation, a reliable recollection of his movements, or information identifying a specific location could help investigators evaluate the existing timeline.

Advances in missing-person identification methods may offer opportunities in unresolved cases generally. However, no verified public announcement establishes that a new forensic technique or genetic genealogy initiative has produced a lead specifically in Reano’s case.


Conclusion and Public Appeal for Information

Patrick Matthew Reano disappeared from Antioch, California, on May 21, 2009, at the age of 36. More than 17 years later, the publicly documented facts remain limited, and the central question of what happened to him has not been answered.

His case illustrates the challenges surrounding disappearances in which little information has been made public. The absence of a detailed public timeline, confirmed evidence, or an official explanation leaves important questions unresolved, but it does not justify treating speculation as fact.

Anyone with credible information about Patrick Reano’s disappearance, his activities around May 21, 2009, or his possible whereabouts is encouraged to contact the Antioch Police Department at (925) 778-2441 and reference case A10-1684.

Information may also be provided through the California Department of Justice missing-person hotline at 1-800-222-FIND (1-800-222-3463).

Even after many years, a reliable piece of information may help clarify the circumstances of a disappearance. Patrick Reano’s case deserves continued attention, careful reporting, and a resolution grounded in verified evidence.
