On March 1, 2016, Sonia Beverly Cassia, a 48-year-old Asian woman, was last seen in San Francisco, California. Standing at 5'2" and weighing approximately 110 pounds, Sonia had black hair and brown eyes. She may have used the last name "Johnson" and had pierced ears. The day after her disappearance would have marked her 49th birthday, but she vanished without a trace, leaving behind few clues and many unanswered questions.
The circumstances surrounding Sonia's disappearance are notably scarce. There is no publicly available information detailing the events leading up to her last known sighting, nor are there reports of personal belongings left behind or signs of foul play. This lack of information has made it challenging for investigators and the public to piece together what might have happened to her.
Sonia's case is documented in several missing persons databases, including the National Missing and Unidentified Persons System (NamUs) under case number MP73622. The San Francisco Police Department is listed as the investigating agency, but there have been no significant updates or breakthroughs reported in the years since her disappearance.
Despite the passage of time, Sonia's case remains on the radar of missing persons organizations and online communities dedicated to solving such mysteries. Websites like The Charley Project and Uncovered.com continue to feature her profile, keeping her story accessible to the public in hopes that new information might surface.

He was a criminal, an abuser, likely who didn't want to face justice of his actions and took his own life because he could not face the consequences of what he did. The victims have told the family his crimes, with evidence. The family knows he was arrested and convicted of possession of CSAM. They know who and what he was. And they're all so equally sick they live in comfort that the victims don't want to retraumatize themselves over everything he put them through. Dont support this families sick parade of using a monster to get sympathy. He was never ashamed of who he was. He loudly boasted his crimes and justified them.
