Washington police are searching for a suspect they believe is connected to the deaths of four people at a home in an upmarket Washington neighbourhood.
The critical clue that led police to 34-year old Daron Dylon Wint: A leftover pizza crust.
Three law enforcement officials with knowledge of the investigation told the Washington Post that Wint was a match for DNA evidence left on the crust of a Domino's pizza delivered to the home on May 13.
They believe that Savvas Savopoulos, 46; Amy Savopoulos, 47; their 10-year-old son, Philip; and housekeeper Veralicia Figueroa, 57, were held captive overnight in the multimillion-dollar northwest Washington home, then killed before the house was set afire the following day. Police said they are still unsure of a motive behind the killings. On the morning of May 14, Savvas Savopoulos's assistant dropped a package off at the house with US$40,000.
Police records also show a series of phone calls involving Savopoulos, his assistant, a bank and an accountant in the hours before the fire. A longtime housekeeper has said she received texts and voice mails from Savopoulos and his wife telling her not to come to the house on May 14.
