Martha Cecilia Bennett, aged 28, was last seen on October 1, 1994, at her home in Los Angeles, California. After that day, she disappeared without a trace and has not been heard from since. At the time of her disappearance, Martha was 5'5" tall, weighed 132 pounds, and had brown hair and brown eyes. She also had several distinguishing tattoos, including the name "JoJo" on her left arm, a heart on her thigh, and "Jesus" on her left ankle. Martha was known to sometimes use the alias "Martha Perez Diaz."

Very few details are available regarding the circumstances of her disappearance, and her case remains unsolved. Authorities have continued to investigate, but no significant leads have emerged over the years. Her case is listed in various missing person databases, including NamUs and the California Department of Justice. Anyone with information is encouraged to contact the Los Angeles Police Department.

Despite the passage of time, the search for answers continues as her family and law enforcement hope for any new information that could help resolve the mystery surrounding her disappearance.
