Police are no longer seeking the whereabouts of a blue Porsche after a quadruple murder in an upscale Washington, DC, neighborhood—but they've released video of a "person of interest" who may have been driving it before it was found burning behind a church. In surveillance video, a hooded figure in dark clothing can be seen moving outside the house where Savvas and Amy Savopoulos were found dead after a fire on Thursday, NBC Washington reports. Two other bodies found in the home are believed to be the couple's 10-year-old son, Philip, and Veralicia Figueroa, one of their housekeepers. Their other housekeeper, Nelitza Gutierrez, tells the Washington Post that she thought something odd was going on Wednesday when she received messages asking her not to come in the next day.
Gutierrez says Savvas Savopoulos gave conflicting information in different messages and sounded unlike himself. "It was something very suspicious because I felt his voice was really tense," she tells the Post. "And it was different than what he had said to me before." She says she also found it strange that Savopoulos said Figueroa was spending the night at the home, something she had never known to happen before. Deepening the mystery, police documents seen by the Post detail some strange events in the surrounding area that week, including reports of a possible prowler, a man banging at the door of a home, and an "aggressive vacuum cleaner salesman" at another home.
