Gibson said the remains have not been positively identified, but detectives believe them to be those of Todt’s wife and children.
He said autopsies conducted Monday determined the cause of death to be homicide.
Gibson said it is believed they died in late December.
He said deputies were previously called to the home to conduct a well-being check after a relative said she was told the Todts had the flu and she had not heard from them in two days.
Gibson said deputies did not make contact with the family and nothing appeared to be suspicious.
Todt is cooperating with investigators, Gibson said. He said Todt took Benadryl and threatened to harm himself Monday, so he was taken to a hospital as a precaution and was released Wednesday morning.
Todt was arrested on a warrant for multiple counts of homicide and one count of animal cruelty.
