A second set of human remains was found Sunday off Lookout Tower Road near Siloam Springs, police said.
A deer hunter found a body Saturday in the woods off the same road, the Northwest Arkansas Democrat-Gazette then reported.
An updated news release Sunday from the Benton County Sheriff's Office said the investigation is ongoing. Neither of the bodies has been identified and both have been sent to the state Crime Laboratory.
