According to a search warrant affidavit for the home where Savvas Savopoulos, his family and housekeeper were killed last month: “A baseball bat with what appeared to be blood on it was located” in the bedroom where three victims were found.

The affidavit describes Savopoulos and his wife Amy as “an adult male with apparent trauma to the rear of his head” and “what appeared to be an adult female with lacerations to her throat and head” respectively.

The two were found in the same room as housekeeper Veralicia Figueroa, who was given CPR and transported to a local hospital. She was later pronounced dead.

Located in the second bedroom on the upstairs level was the body of ten year-old Philip Savopoulos. This is the room where investigators say the fire to the home was started. The boy’s body was so badly burned, fire responders could not determine his gender or age, listing him as an “adult individual.”

The document, unsealed in DC Superior Court earlier today, notes that detectives observed a surveillance camera on the exterior of the home. ABC News reported earlier that the recording system for that camera appeared to have been removed from the home.
