In a Facebook post from the Anderson County Sheriff's Office, the late actor's relative, Tony Boseman, was reported missing on Sunday. ACSO has since updated their post to note that, as of 3:08 p.m. ET on Tuesday, Tony "has been located."
"Just before 2 p.m., the Sheriff's Office [and South Carolina Law Enforcement Division/SLED] teamed up and came across him on foot around half a mile away from his house — which is ironic because we've searched miles, but it's understandable because it's a wood area, almost like a wooden ditch," ACSO Public Information Officer Shale Remien tells PEOPLE.
"He has been reported missing a time or two here. We're hoping that this is the last and they can come up with some sort of game plan moving forward," continues Remien, adding that, once found, Tony was "airlifted to a nearby hospital," Prisma Health.
Remien says, "We know that he was severely dehydrated. We're hoping for the best, and that with some quick medical attention, he can get back on his feet."

According to a release from authorities, before they located Tony, he had last been seen in the Boseman Road area around 3:30 p.m. Sunday. At the time, he was wearing camo pants, a green shirt, black shoes and a Los Angeles baseball cap.
On Tuesday, the SLED assisted in searching for Tony with a helicopter, WYFF News 4 reported. ACSO also had a helicopter on the scene. The release also noted that Tony suffers from dementia and type 2 diabetes.
Remien tells PEOPLE that the efforts to locate Tony included the use of "drones, horses even, with canines, with two choppers, including from SLED and [with] our own Air 1 chopper."
"[We were] searching the grounds, air, water, all the different ways you can search, a hands-on effort," she adds. "This would be day three and this was the most critical day just because of his history with dementia as well as diabetes, so to be without your medicine and to be without water for that long is obviously worrisome."
