Danny Holt Jenkins, 51, of Akron, was being held Tuesday without bond in the Tuscarawas County jail. The bodies of Duane Lockard, 60, and William Lockard, 61, both of Suffield, were found Nov. 2 in the woods near Tappan Lake in Stock Township.
Police said the two were shot Oct. 31 while deer hunting. Their wallets and $5,000 in cash were missing.
Harrison County Prosecutor Matthew Puskarich said he expects to convene a grand jury to hear the case in the next two weeks.
Jenkins, who has not entered a plea, is charged with two counts of aggravated murder. Puskarich said a preliminary hearing will be scheduled in front of Harrison County Judge Michael Nunner within the next nine days.
The Portage County Sheriff's Department is also involved in the case, and is trying to determine if there is a link between Jenkins and four other unsolved murders in the Deerfield area during a 12-month period.
Portage County Sheriff Duane Kaley said he is asking Jenkins about all of the homicides that occurred in that area, including the murder of 17-year-old Kathryn Menendez of Alliance.
The remains of her body were discovered Aug. 25, 1994, in a wooded area off of Fewtown Road in Deerfield.
"There's certainly no indication at this point in time that he'd (Jenkins) know anything about that. He didn't find the individual," Kaley said.
Jenkins was one of the first to find the body of an unidentified woman on Nov. 4, 1994, also in a wooded area near Fewtown Road on the north side of the Berlin Reservoir, southwest of the Deerfield Circle. Her identification is still undetermined.
On Nov. 6, 1993, Lisa Watters, 32, and Andy Hussey, 31, were shot and killed while on the beach at the Berlin Reservoir. It is believed they were killed with single shots fired by someone on the bluff about 40 feet above where the bodies were discovered.
Andy Hussey was the son of Lt. Gordon Hussey of the Portage County Sheriff's Department.
Investigators from Jacksonville, Fla., also are trying to determine whether Jenkins may have been involved in two 1993 shooting deaths there.
