On April 30, 1991, Alvin Kayser, a 60-year-old male, was last seen in Jeffersonville, Pennsylvania, in Montgomery County. Publicly available records describe him as a White/Caucasian man with brown hair and brown eyes who wore glasses. At the time he disappeared, he was listed as standing approximately 5 feet 7 inches to 5 feet 10 inches tall and weighing about 160 to 165 pounds. The available case information does not describe a known destination, a final conversation, a vehicle, clothing, or belongings connected to his last known movements; instead, the documented circumstances of his disappearance remain unknown. What is clear is that Alvin’s life intersected with a quiet and unresolved moment in Jeffersonville, after which he was not publicly reported to have been seen or heard from again.
The case was reported to and is associated with the West Norriton Police Department, which is listed in public missing-person records as the investigating agency.
Those records identify the agency case number as 910510010 and show that the case was reported on May 10, 1991, a short time after Alvin’s last known contact. The passage of time has left the public record sparse, and there are no detailed public accounts explaining what Alvin was doing before he vanished, whether anyone immediately knew he was in danger, or whether investigators developed a specific theory about what happened to him. In that absence, the known facts carry a particular weight: his name, his age, his physical description, the place he was last known to be, and the date that became the marker between his known life and an enduring uncertainty.
NamUs lists Alvin Kayser under Missing Person case MP42401, a national missing-person record created to preserve identifying details and support comparisons with unresolved cases involving unidentified or unclaimed persons. The NamUs program is described by the U.S. Department of Justice and related federal sources as a centralized resource used by law enforcement, medical examiners, coroners, investigators, and families to help resolve missing, unidentified, and unclaimed person cases. In Alvin’s record, the information remains limited but important: his last contact date is April 30, 1991, his last known location is Jeffersonville, Pennsylvania, and the circumstances are listed as unknown. The record also notes that DNA information is pending, while other common details, such as clothing, transportation, and distinctive physical features, are not publicly provided.
Public summaries of Alvin’s disappearance reflect the same painful lack of detail. Uncovered’s case page states that no details are available regarding the circumstances of his disappearance beyond the fact that he was last seen in Jeffersonville on April 30, 1991, and that he has not been seen or heard from since. That limited public record can be deeply difficult for families and communities, because unanswered questions often remain where a fuller story should be: where Alvin was headed, who may have seen him last, whether he left voluntarily, became lost, suffered a medical crisis, encountered harm, or disappeared under circumstances that were never discovered. Without publicly documented answers, the case rests on a small number of facts and the hope that someone may still know something that could help explain what happened.
Alvin Kayser’s disappearance is therefore remembered as a long-unresolved missing-person case from Jeffersonville, Pennsylvania, involving a 60-year-old man whose last known contact was on April 30, 1991. He was described as a White/Caucasian male with brown hair, brown eyes, and glasses, approximately 5 feet 7 inches to 5 feet 10 inches tall and 160 to 165 pounds. The West Norriton Police Department is identified as the investigating agency, and public records continue to preserve the basic details of his case while offering few answers about the circumstances. In overview, Alvin’s case is a quiet but significant missing-person case defined by scarce public information, an unknown set of circumstances, and a decades-long need for resolution for anyone who cared about him and still hopes to understand what happened after he was last seen in Jeffersonville.Last Seen: Apr 30, 1991
