Nanci Terese Nelson, last seen August 26, 1998 in Castle Rock, Colorado, remains missing. She was 29 at the time and described as a white female, brown hair, brown eyes, 5 feet 2 inches tall, about 110 pounds, with a black panther tattoo on her left shoulder and a flower tattoo on her left breast. Reports say she was last known to have been living in Oregon and used the names Nanci Terese Conradson and Tanya Williams.

Her parents reported her missing in 1999 after a prolonged lack of contact; the delay between her last known sighting and the official report has been a notable complication in the investigation. The Douglas County Sheriff’s Office lists the case as an active cold case and continues to seek information about her whereabouts or what happened to her.

Did anyone in Oregon or Castle Rock in 1998-1999 know Nanci Nelson, the aliases she used, or the places she might have stayed?
