Mary Elizabeth Rico, 50, vanished from her Camelot Drive home in Oceanside, California after being last seen there on April 2, 1992. She was preparing for her niece’s wedding and did not attend the event nine days later. Mary was politically active and known for championing liberal causes.

Initial inquiries flagged a neighbor’s report that Mary appeared in the background of a television newscast about protest groups, but her family pressed for more when she made no contact. When her son checked the house he found a broken glass patio door, smeared blood on her bed, and a cut telephone line. Both of her cars remained in the garage and personal items including her purse, wallet, and suitcases were untouched. Police reopened the investigation, conducted thorough searches and in 1998 excavated the former residence’s foundation after a suspicious concrete patch was found, but no conclusive evidence has been reported.

What can anyone who knew Mary or saw unusual activity in Oceanside around April 1992 add to this timeline?
