On the evening of May 4th, 2011, the owners of an apartment building on East Moore Street in Norristown, Pennsylvania, entered the home of twenty-nine-year-old Jessica Manzanero and made a horrifying discovery. Jessica, a mother of two, was lying face down on the living-room floor. Around her was a large amount of dried blood.
Police were called to the apartment at approximately nine p.m. Investigators quickly realized that Jessica had not died that evening. The condition of the scene suggested that considerable time had already passed. An autopsy subsequently determined that she had suffered multiple stab wounds. Authorities believe she was killed on or about May 2nd, 2011, roughly two days before her body was discovered. What happened inside the apartment during those missing two days is still a mystery.
Exactly when Jessica was last known to be alive has not been disclosed. Nor have authorities explained why the property owners entered her apartment on May 4th, whether anyone had been trying unsuccessfully to reach her, or whether concerns had been raised about her absence.
Further, publicly accessible accounts do not establish whether a murder weapon was recovered. They do not say whether there were signs of forced entry, whether anything had been stolen, whether the apartment had been disturbed, or whether investigators recovered useful fingerprints, DNA, or other physical evidence. Likewise, investigators have not publicly described the precise number or location of the stab wounds.
In the years following Jessica’s death, the investigation attracted little sustained public attention outside Montgomery County.
Then, fifteen years after the murder, Montgomery County detectives announced that something had changed. In June 2026, Montgomery County District Attorney Kevin R. Steele announced a renewed effort to solve Jessica’s killing.
Detectives, Steele said, had recently uncovered new information relating to the murder. Officials deliberately declined to say what that information was. The discovery was nevertheless considered significant enough to prompt a fresh public appeal and a $2,500 reward for information leading to the arrest and conviction of the person responsible.
Steele stressed that county detectives had continued to pursue unsolved murders and appealed directly to anyone who might have retained information about what happened to Jessica Manzanero. He urged witnesses not to dismiss seemingly minor memories, saying that “no detail is too insignificant” to share with investigators.
Exactly what prompted the renewed activity remains unknown. Authorities have not said whether the development involves a new witness, previously undisclosed physical evidence, forensic testing, an old statement reexamined by detectives, or information obtained during an unrelated investigation. There has also been no public indication that the new information points to a particular individual.
Since the announcement, however, there have been no new developments in the case.
