The man who held three members of a D.C. family and their housekeeper hostage in 2015 before brutally killing them was sentenced to four life sentences without the possibility of parole, a judge announced Friday.  In what prosecutors called “the most heinous crime anyone has ever committed in this city,” Daron Wint was convicted of killing Sav­­vas Savopoulos, 46, his 47-year-old wife, Amy, their 10-year-old son, Philip, and the family’s 57-year-old housekeeper, Veralicia “Vera” Figueroa. The four victims were beaten with baseball bats and stabbed repeatedly before being set on fire.

“The conduct was heinous, atrocious and cruel, D.C. Superior Court Judge Juliet McKenna said Friday. “Holding them hostage in their home for 24 hours. The conduct is incomprehensible.”

The sentencing comes nearly four years after 37-year-old Wint, who was previously a welder for the Savopoulos, held the family hostage for $40,000 cash ransom. During a six-week trial, prosecutors detailed how Wint broke into the Savopoulos home in May 2015 and confronted Figueroa and Philip, who was home sick from school. The former welder then forced Amy Savopoulos to call her husband and ask him to come home from work. He held all four individuals hostage overnight before murdering them, prosecutors said. Wint’s public defenders maintain that he is innocent, arguing at trial that his brother and his half brother were the true killers.
