One adult and three children were found dead in a suburban home in a typically peaceful neighborhood near Tallahassee, Florida, according to CNN.

Medical professionals are working to determine the causes of death, and a homicide investigation is under way.

"There's obvious violence in the home," David McCrane, a police spokesman, said, according to the Associated Press. "How that violence transpired, we're not sure."

The children were 6 and 3-years-old.
