MARTINS FERRY — Brian Goff and Joni Davis were last seen more than 90 days ago, and now another agency is getting involved in the search for them.

Goff, 64, and Davis, 55, both of Martins Ferry, have been missing since June 10. That was the date they were last seen, leaving Pizza Hut on National Road in St. Clairsville. They were driving a light blue 1990 Oldsmobile Delta 88 with Ohio license plate number of EYA 7482. Belmont County sheriff’s Chief Deputy James Zusack previously said that Goff is Davis’ caregiver, since Davis had suffered a traumatic brain injury. Family members said the couple always followed a strict routine, but they have not been spotted at any of their usual spots since June 10.

Early in the investigation, the Ohio State Highway Patrol used a search plane to try to find their vehicle from the sky in the local area. Zusack said the Belmont County Sheriff’s Department wants to find the pair and needs all the help it can get, so it is now accepting the help of the FBI.

Zusack said investigators have hit the 90-day mark in the case, and they are still taking tips, following leads and working with Jefferson County Sheriff’s Department but needed the resources the FBI could offer.

“They have resources and tools which can help us further our search for the couple,” Zusack said. “We are very appreciative of the FBI’s assistance and hope that in working with them we can find the two.”

Zusack also urges anyone who believes they may have seen the couple or may have knowledge as to their whereabouts is urged to call the Belmont County Sheriff’s Office at 740-695-2212, the Jefferson County Sheriff’s Office at 740-283-8600 or the FBI at 614-224-1183.
