BOYNTON, Okla. — UPDATE, 2/15/2022, 11:30 a.m.: Lighthorse Police confirm that a suspect is in custody, connected to the death of Thomas Fultz. However, the ATF has taken over the case, as the cause of death cannot be determined due to the condition of the body.

Family members tell FOX23 investigators confirmed remains found in Boynton Saturday are those of Thomas Fultz.

The Muscogee Nation Lighthorse Police confirmed human remains were discovered around 11 a.m. Saturday in Boynton. Officers say a man called them when his dog came upon them.

Fultz’s sister Channette Fultz says she had a feeling the human remains found in Boynton Saturday were those of her brother.

She adds there’s some relief knowing they can bring him home and don’t have to keep searching.

Fultz had been missing out of Okmulgee since September. His truck was found in Haskell just a few miles away from where the remains were found.

Fultz’s family members are remembering him as a funny and charismatic family man. His sister believes his big heart and willingness to help people caused what happened here and it’s unfortunate.

The medical examiner hasn’t given a cause of death just yet but investigators are treating it as a homicide. Muscogee Creek Nation Lighthorse Police, the Muskogee County Sheriff’s Office, Medical Examiners Office and the FBI are working together to conduct this investigation.

There is no word on services yet.
