On Thursday, April 2, 2009, emergency responders were called to a residence in the 900 block of San Antonio Avenue in Pomona, California. Upon arrival, authorities discovered the lifeless body of Maria Pelayo, a Hispanic female who was pronounced dead at the scene. The incident occurred inside a residential stretch of the city, bringing patrol units and forensic personnel to cordoned-off blocks along San Antonio Avenue as neighbors looked on in concern.
The Los Angeles County Department of Medical Examiner took jurisdiction over the investigation into her death. Following an examination, the coroner classified the manner of death as a homicide, officially entering the case into county records. However, authorities have withheld or left unspecified the exact mechanism of trauma, listing the cause of death in public summaries as other. Specific details concerning the nature of the injuries or physical trauma encountered at the scene were not released to the public, preserving crucial investigative elements known only to investigators and whoever was responsible.
Detectives with the Pomona Police Department launched a homicide investigation to piece together the events leading to the killing. Investigators conducted neighborhood canvases, interviewed potential witnesses in the surrounding neighborhood, and examined physical evidence recovered from the San Antonio Avenue address. Despite efforts to uncover a clear motive, identify acquaintances or visitors present near the time of death, or find surveillance footage from nearby corridors, initial inquiries produced few substantial leads.
The city of Pomona, situated in the eastern expanse of Los Angeles County at the boundary of the Inland Empire, faced ongoing public safety challenges in 2009. Throughout that year, the municipality recorded more than twenty homicides investigated by local detectives. Amid this elevated caseload, incidents lacking immediate eyewitnesses or obvious forensic links often encountered severe hurdles, leaving families waiting in anguish for answers.
In the years following the tragedy, the case grew quiet. Law enforcement agencies have not announced any formal suspects, persons of interest, or arrests in connection with the crime. The investigation remains active under the jurisdiction of the Pomona Police Department's Major Crimes Unit, where cold case detectives continue to periodically review unsolved files in the hope that emerging forensic technology or new statements will break open old cases.
More than a decade and a half later, the death of Maria Pelayo remains officially unsolved. Detectives and community advocates continue to urge anyone who resided near the 900 block of San Antonio Avenue in April 2009, or who may hold information regarding the circumstances surrounding her death, to contact the Pomona Police Department Detective Bureau or submit an anonymous tip through Los Angeles Regional Crime Stoppers.
