Gilchrist County Sheriff Robert Schultz at a news conference identified the man as 51-year-old Don Spirit. He said the children ranged in age from 3 months to 10 years old. He would not say if woman killed was the mother of the children.
Schultz said a deputy who arrived on a report of a shooting Thursday made contact with Spirit who later committed suicide.
He said Spirit was the only suspect and that some people were left alive at the home.
He would not identify those killed.
