Robert Paul Johnson, 27, was found dead in his Mission Beach apartment in San Diego on April 24, 1993. He managed his apartment complex and attended a dinner party on April 22; a friend dropped him at home about 11:30 pm and was the last person known to see him alive. When Johnson failed to show up for work over the next two days, a friend checked on him and discovered his body in the bathroom. He had been strangled to death.

Johnson was described as friendly and often invited people he met on the Mission Beach boardwalk into his home, a detail investigators have said could be relevant to what happened that night. The case remains unsolved; authorities have made repeated appeals and offered rewards for information to help identify the perpetrator. If anyone knew Johnson, saw him the night of April 22, 1993, or has information about visitors to his apartment, please come forward.
