Summary based on the NamUs case record (MP25821) and 5 other sources
Mirian Elizabeth Mancia, 29, was last seen on May 12, 1988, near Goodman Avenue and Ventura Boulevard in Los Angeles, California. She is described as a Hispanic female, standing 5'3" and weighing around 110 pounds, with black hair and brown eyes. On the day of her disappearance, she was wearing a white blouse and blue jeans. Mancia may have also used the alias Mirian Elizabeth Barahona.

Her case has been classified as an endangered missing person, and authorities suspect foul play may have been involved. Despite investigations, few details have surfaced about the circumstances surrounding her disappearance, and she has not been heard from since that day. The Los Angeles Police Department is continuing to seek information that could help solve this decades-old case.

If you have any information, you are encouraged to contact the LAPD’s Adult Missing Persons Unit.
