QUINCY, Fla. (AP) — Investigators say three people found dead inside a burning Florida home were slain.

The Tallahassee Democrat reports that Quincy police said Monday that the victims found early Friday had been killed, but it couldn't be determined whether they were slain before or after the fire was set. Capt. Robert Mixson told reporters the home had been abandoned for years and the victims' identities have not been confirmed.

He declined to say how they died.

The U.S. Bureau of Alcohol, Tobacco, Firearms and Explosives, the Florida Department of Law Enforcement and the state fire marshal's office are assisting Quincy investigators.
