Summary based on the NamUs case record (MP26087) and 8 other sources
Lisa Renee Knox, a 28-year-old woman, was last seen on May 11, 1993, in the 1000 block of 22nd Street in Los Angeles, California. She vanished without a trace and has not been heard from since. Lisa is described as being 5'6" tall, weighing 110 pounds, with black hair and brown eyes. She may have used the last name "Davis."

Her disappearance raised concerns due to potential ties to the infamous Grim Sleeper serial killer, Lonnie David Franklin Jr. Franklin was convicted of multiple murders, and Lisa's family suspects she may have been one of his victims. Several women involved in similar circumstances—connected to drugs and prostitution—went missing around the same time, with some of their identification found in Franklin's possession. While Lisa has not been officially linked to Franklin's confirmed victims, her case remains open and under investigation.

Lisa's body has never been found, and authorities continue to seek answers. Anyone with information is encouraged to contact the Los Angeles Police Department.

Last Seen: May 11, 1993
