Summary based on the NamUs case record (MP59131) and 3 other sources
William Matczk was 62 years old when he was last seen in Philadelphia, Pennsylvania, on November 1, 2018. He is listed as a male, White/Caucasian, and the public missing-person record places the beginning of his disappearance in the city where he lived his daily life, with the available details centering on a simple errand that became the last known point in his story. According to public case summaries drawing from NamUs, William’s roommate reported him missing on November 3, 2018, saying that William had left for the bank on November 1 and did not return. That brief account leaves a painful silence around what happened after he left, and it is the kind of ordinary moment that makes the case especially troubling: a person going out for a routine purpose and then vanishing from the reach of those who expected him home.

The identifying information released publicly describes William as having blond or strawberry-colored hair and brown eyes. Public listings give his age at the time of the incident as 62, with the NamUs case number MP59131 attached to his case, and one public listing records his height as 72 inches and weight as 160 pounds; other public missing-person listings associated with area alerts have described a broader height range of 6 feet to 7 feet 8 inches and a weight range of 160 to 175 pounds. These details matter because, in a missing-person case with so few known circumstances, physical identifiers can become some of the most important information available to the public and to anyone who may have seen something. They also help preserve William’s identity beyond the case number: he was a man with a name, a face, a routine, and people who noticed when he did not come back.

The known timeline is narrow. William was last known to have left for the bank on November 1, 2018. Two days later, on November 3, his roommate reported him missing, indicating that his absence was not normal and that someone close enough to know his movements became concerned when he failed to return. Publicly available sources do not provide a detailed route, the name of the bank, the time he left, what he may have been wearing, whether he was traveling on foot, by public transportation, or in a vehicle, or whether he made it to the bank at all. That lack of detail leaves the case suspended around a few confirmed points: William was in Philadelphia, he was expected to come back, and the errand that should have ended routinely instead became the starting point of a missing-person investigation.

NamUs lists William Matczk’s case as Missing Person / NamUs #MP59131, and Uncovered’s case page repeats the central circumstances from NamUs: the roommate’s report, the bank errand, the last-seen date, and the Philadelphia location. The public record is spare, but its simplicity should not lessen the seriousness of the disappearance. A missing person case with limited public information can be especially difficult for loved ones and investigators, because there are fewer confirmed facts to anchor the search and fewer public details that might trigger a memory from someone who crossed paths with him. In overview, William Matczk’s case begins with a 62-year-old man last seen in Philadelphia on November 1, 2018, reportedly leaving for the bank; it continues with his roommate reporting him missing on November 3 after he did not return; and it remains publicly defined by the unresolved question of what happened to William after that ordinary errand became the last known chapter in his story.
