Diane Marie Ayres, 23, was found dead on September 4, 1999, in a remote area along Golf Course Drive in Balboa Park in San Diego. She was discovered nude and had been strangled; investigators believe her body was dumped at that location. Diane had left her Golden Hills apartment on Hawthorn Street on September 2, 1999, telling her mother she was going out for the evening and did not return.

Diane was known to frequent several clubs and bars, including In Cahoots and venues near the 32nd Street Naval Base and the Marine Corps Recruit Depot. Her social circles and regular hangouts were a key focus for the San Diego Police Department as they tried to reconstruct her final movements. A reward of up to $1,000 was offered for tips that could lead to an arrest, and police asked anyone with information to contact the SDPD Homicide Unit or submit an anonymous Crime Stoppers tip.

Does anyone who knew Diane or who spent time at those clubs and military venues in early September 1999 have information that could help identify her killer?
