-- Police released surveillance video of a person of interest in the deadly blaze that killed a family of four in a Washington D.C. home last week.
The video, released Saturday night, shows a hooded figure carrying a white object, running past an unidentified building.
The video also shows a "vehicle of interest," a blue Porsche convertible with D.C. license plates registered to the family, which was seen at the house before the fire broke out.
Police said the car was later abandoned and set on fire on Arlington Road in Prince George’s County.
Two of the identities of the victims -- Savvas P. Savopoulos, a 46-year-old corporate executive, and his wife, Amy -- were confirmed by police in a press conference on Friday.
The two other bodies are not identified but are believed to be the couple's 10 year old son and the family's housekeeper, police said.
The fire is being investigated as a homicide and arson. Blunt-force or sharp object injuries were found on at least three of the four victims, police said.
"I've been here for 25 years and nothing like this ever happens. So it's really kind of just rattling," a neighbor said.
