Jessica Dawn Adams, 44, was last seen in Kennewick, Washington, on August 31, 2020, with her final known communication a social media post at 3 a.m. on September 1, 2020. A resident of Kennewick who was reportedly unhoused at the time, she has not been heard from since and the circumstances of her disappearance remain unexplained.

Adams is described as a white female, brown hair, brown eyes, 5 feet 9 inches tall and about 150 pounds. Distinctive tattoos have been emphasized in public appeals: a horse shaped like a heart on her right forearm; two red roses and three butterflies on her left thigh; plus additional tattoos on her left ankle, right ankle and back. Clothing and personal belongings at the time she vanished are unknown. Her social media listed past addresses in Idaho and California, and it is believed she may have left the Kennewick area.

The case drew public attention when the Kennewick Police Department issued a January 2021 appeal for information; delays between her last activity and that public notice have been highlighted as an obstacle to the investigation. Anyone who knew Jessica, saw her in late August or early September 2020, or has information about her tattoos or movements is asked to come forward.
