Investigators in Humphreys County said two victims of a house fire were dead before the fire started.
Police said Carl and Elaine Hewitt were shot to death before their home caught fire.
A third body was found at the scene but has not yet been identified.
The Waverly home caught fire last week and was one of two homes set on fire.
Police said their search of the fire scenes turned up a gun they believe was used to kill the Hewitts before the fire.
