MOUNTAIN VIEW, Ark. (AP) — Authorities in Arkansas say they’ve identified a person of interest in connection with the fatal shootings of four people last week in a rural community.

Arkansas State Police say the person is now jailed on unrelated charges. Police did not release that person’s name or say how they may be connected to the deaths last week in rural Stone County, about 75 miles (120 kilometers) north of Little Rock.

According to state police, 77-year-old Shirley Watters and her 55-year-old son, James Watters, were found dead April 21 afternoon by a family member.

State police said both had gunshot wounds. About eight hours later, investigators were called to a nearby home where William Clinton Trammell, 75, and his wife, Sharon Trammell, 72, were found dead, also with gunshot wounds, state police said.

“While area residents should continue to be vigilant at their homes and while traveling through the area, the state police has not found any evidence to indicate an imminent threat related to this particular investigation,” state police said in a statement Tuesday night.
