Case Description

Any updates on this case? Let us know!
Summary based on the NamUs case record (MP102075) and 3 other sources
Monica Nanette Weems, a 20-year-old woman, was last seen on August 15, 1990, in Richmond, California. At the time of her disappearance, she was described as 5'2" tall, weighing around 125 pounds, with brown hair and brown eyes. Monica was known to frequent the area around 7th and Pennsylvania in Richmond, a fact that may provide insight into the circumstances of her disappearance. Despite being missing for decades, her case was only recently added to the NamUs database in 2023, and no new leads have surfaced since then.

Authorities continue to investigate her disappearance, but there have been few clues as to what happened to Monica on the day she vanished. Her case remains unsolved, and anyone with information is urged to contact local law enforcement to assist in the investigation.
Last Seen: Aug 15, 1990
