Surveillance video has been released of a person of interest in the murders of four people in a Washington, D.C. mansion that was later set on fire.

Two victims were identified as corporate executive Savvas Savopoulos and his wife, Amy Savopoulos. Two others were tentatively identified as their 10-year-old son Philip and housekeeper Veralicia Figueroa.

The home is located just blocks from Vice President Joe Biden’s official residence.

Blunt force or sharp object injuries were found on three of the four victims, investigators say. Authorities have also determined that the fire was intentionally set.

The couple’s blue 2008 Porsche was also found torched about 35 miles from the couple’s home. A hooded figure was caught on camera running from the scene of the torched car.
