Denise Ann Daneault was 25 when she was last seen in Manchester, New Hampshire, on June 8, 1980. A divorced mother of two, she left a private club downtown about 1:30 a.m., reportedly to attend a party she never reached. Denise lived with a roommate on Hayward Street and it was unusual for her to vanish without warning.

Investigators have examined possible links between her disappearance and Terry Peder Rasmussen, who lived nearby at the time and was later connected to other disappearances and murders, but no concrete evidence tying Rasmussen to Denise’s case has emerged. In recent years authorities carried out extensive searches, including multi-day digs in Manchester, but those efforts produced no significant breakthroughs. Her case remains unsolved and investigators continue to seek leads.

If anyone knew Denise, where she spent time that night, or has information that wasn’t previously shared with police, please come forward.
