Richardson was last seen on Chapin Street in St. Augustine, Florida on October 20, 1995. She has never been heard from again. She was reported missing by her son.

In 1999, the serial killer William Darrell Lindsey Sr. pleaded guilty to second-degree murder in connection with Richardson's case. A photograph of Lindsey is posted below this case summary. He lead police to a three-acre, alligator-filled pit near Murray Middle School in St. Augustine, saying he had put Richardson's body there. Police could not find her remains, but they had enough evidence to prove he had killed her. Lindsey also pleaded guilty to the murder of Donetha Snead, whose body has also never been found, and to four other murders. He will not be eligible for release until 2024, by which time he will be 89 years old.

Richardson is a native of California. Like all of Lindsey's victims, she was involved with drugs and prostitution, but it is extremely out of character for her to leave without contacting her friends and family. Foul play is suspected in her case due to the circumstances involved.
