Terri Foster was 21 when her partially clothed body was found in Vancouver, Washington, on December 24, 1977. Her body was discovered about 12:30 p.m. in a corner of David Douglas Park, then under construction, near the park’s southwest area off North Garrison Road. An autopsy ruled the death a homicide: cerebral edema and hypermia secondary to strangulation. The examination documented contusions to the scalp, left orbit, and nose, and evidence of sexual assault. Investigators concluded the rape and killing most likely occurred sometime after 2:00 a.m. that morning.

Detectives developed a person of interest after learning someone identifying himself as Dennis had visited Foster’s home the night she was last seen. A composite sketch based on witness descriptions was later matched to photos of Dennis Allen David. Polygraph tests given to David on December 28 and 29, 1977, produced answers judged consistent with deception about seeing Foster that night and about involvement in her death. The homicide remains unsolved.

If anyone knew Terri, saw her the night of December 23–24, 1977, or has information about Dennis Allen David from that time, please share what is known.
