Terry Lynn Collier was 30 when she left Aurora, Illinois, and was last known to be in San Bernardino County, California, on January 1, 1979. After leaving Illinois she is known to have traveled through Southern California, with time spent in San Bernardino and Riverside and possible time in San Diego; she may have stayed in homeless shelters while in the state. Family contact stopped after she left Illinois in 1979.

Investigators later found she was in San Diego in 2004 and obtained a photograph from that year. There is also information that she may have moved to Florida’s east coast between 2008 and 2009. Collier is described as 5 feet 2 inches, about 125 pounds, with brown/red hair, blue eyes, and eyeglasses. The San Bernardino County Sheriff’s Department is the investigating agency.

If anyone knew Terry Lynn Collier, saw her in Southern California after 1979, or has information about a possible move to Florida in 2008–2009, please share what is known.
