Scott Wilson, a Kitsap County sheriff's deputy, said the body was found in a wooded area near the Steele Creek Mobile Home Park. Jenise lived there with her parents, who told police they last saw her when she went to bed Saturday night.
"We're fairly confident it's her, but we have to go through the process," Wilson said.
According to Wilson, an autopsy is being performed. Investigators hoped to get confirmation of the identity, as well as information on how and when Jenise died.
The parents did not report their daughter's disappearance to police until late Sunday. They said she frequently went off to play.
Her father, James Wright, has a history of molestation charges and was convicted of a misdemeanor for fondling a teenage girl. But Wilson described the parents during the search as "very very cooperative."
By Tuesday, more than 100 local, state and federal law enforcement officers were involved in the search and investigation.
