 LATEST UPDATE: Suspect identified in NW DC quadruple homicide 
 
 WASHINGTON (WUSA9) -- Law enforcement sources tell WUSA9 that an assistant dropped a package filled with $40,000 in cash before four people were killed inside a D.C. mansion that was then set on fire. 
 
 A source also says detectives believe the killers tortured Phillip Savopoulos, 10, as they tried to force his father to come up with the cash. 
 
 On May 14, Phillip Savopoulos was found dead, along with his parents, 46-year-old Savvas and 47-year-old Amy Savopoulos, and housekeeper Veralicia Figuaroa, 57, at a mansion on Woodland Drive near the National Cathedral.

 Detectives believe the killers held the four victims captive for about 10 hours, and that they successfully forced the Savopoulos family to get them the money.

 Metropolitan Police Department Chief Cathy Lanier has confirmed that three of the four victims were beaten or stabbed before the killers set fire to the almost $5 million mansion. 
 
 At one point, the killers may have ordered pizza. Two clerks at a Domino's Pizza tell WUSA9 that a delivery person came to the house. 
 
 Figuaroa's husband, Bernado Alfaro, reportedly went to the mansion on Thursday morning to look for his wife. He said he thought someone was home, but no one answered the door. A short time later, Savvas Savopoulos contacted Alfaro saying he needed Figuaroa to stay at the house because Amy Savopoulos was sick and might need to go to the hospital. Alfaro told CBS News that that made little sense to him because his wife cannot drive nor speak English well. Hours later, Alfaro heard that the family had been murdered, WUSA9's Bruce Leshan reported. 
 
 There were a lot of video cameras around the house, but the only video police have been able to release is a shadowy tape of a figure running, apparently near the scene where a suspect torched the Savopoulos' Porsche on Annapolis Road in Prince George's County. 
 
 Funeral services for the Savopoulos family are scheduled for May 25 at noon at the Greek Orthodox Cathedral. The viewing will be the night before. The Savopoulos' also have two daughters, but both were away at boarding school during the murders.

 [ Update: Suspect worked for victims’ family business, police say ] 
 
 D.C. police said late Wednesday that they have identified a suspect in the killings of Savvas Savopoulos, his wife, young son and housekeeper, who authorities believe were held captive in the family’s Northwest Washington home. 
 
 Police said they had obtained a warrant for the arrest of Daron Dylon Wint, who they said is 34 and is from Maryland. They said they do not know his whereabouts. 
 
 The stunning break in the case came after police matched Wint to DNA found on the crust of a Domino’s pizza that had been ordered to the house the night of May 13, as the victims were being held, according to three law enforcement officials with knowledge of the investigation 
 
 The next morning, Savvas Savopoulos’s personal assistant dropped off a package containing $40,000 in cash at the home, according to the officials and police documents.

 Hours later, the multimillion-dollar house was on fire, and the four occupants were dead. When firefighters arrived that afternoon, the cash was gone, as was a blue Porsche owned by the family. The vehicle was found later that day, torched in a church parking lot in Prince George’s County. 
 
 Information about the money drop adds a perplexing new dimension to a case that has riveted Upper Northwest Washington as well as the District’s business and society circles with which the couple had been intimately involved. Savvas Savopoulos, 46; Amy Savopoulos, 47; their 10-year-old son, Philip; and housekeeper Veralicia Figueroa, 57, all were killed. 
 
 Law enforcement officials, who spoke on the condition of anonymity because the investigation is ongoing, said detectives think that the family and housekeeper had been held overnight in the home near the vice president’s mansion and that at one point they may have been bound. 
 
 Authorities said they are investigating whether there are any links to Savvas Savopoulos’s business or personal life. Savopoulos owned or was involved in several businesses. 
 
 Police documents, obtained by The Washington Post, show that the assistant had been helping Savopoulos, who was rushing to complete a martial arts studio in Chantilly, Va. It was unclear whether the assistant made contact with anyone inside the house when he delivered the money. Police documents show that he was at a hardware store near the Chantilly studio in western Fairfax County from 11:30 a.m. to noon May 14 and was still in Virginia when 911 calls came later that afternoon about the fire 30 miles away in the District. 
 
 D.C. police have not disclosed whether they know of a motive for the killings. But a timeline of Savvas Savopoulos’s movements is beginning to emerge from the police documents. 
 
 The documents show a flurry of phone calls among Savvas Savopoulos, a bank, an accountant, the personal assistant, a construction company executive and Savopoulos’s American Iron Works company in the hours before the fire. The calls started shortly after 7 a.m. May 14 and ended just before noon. The fire was reported at 1:15 p.m.

 The assistant, who did not return messages left on his cellphone Wednesday, tried to call Savvas Savopoulos about 1:40 p.m. but got no answer, the police documents show. Savvas Savopoulos had called the assistant at 11:54 a.m. — the last incoming or outgoing call he made or answered before the fire. 
 
 The four victims were found on the second floor of the Savopoulos home in the 3200 block of Woodland Drive NW. Police have said little about how they were killed, other than that three had wounds consistent with blunt force or a sharp object. Authorities also have said the fire was set. 
 
 Savvas Savopoulos was the president and chief executive of American Iron Works, which supplies metal to large building projects across the region. He and his wife were active in Washington social circles and with charitable and political fundraising. Their two teenage daughters were away in boarding school at the time of the killings. 
 
 The funeral for the three Savopoulos family members is June 1 at St. Sophia Greek Orthodox Cathedral in Northwest Washington. Figueroa’s body will be flown to her native El Salvador for burial.

 Authorities have been trying to determine when the family and housekeeper were last safe and when they encountered the killer or killers. 
 
 One longtime American Iron Works employee told police that he last saw Savvas Savopoulos at the Chantilly studio about 6 p.m. May 13, according to police documents. That employee told investigators that workers had been rushing to complete the martial arts studio, which had a grand opening planned for May 15. Savopoulos appeared on several Internet boards as a martial arts hobbyist and was involved in some exclusive clubs for the sport. 
 
 A second housekeeper, Nelitza Gutierrez, has reported a strange series of voice mails and text messages from Savvas and Amy Savopoulos beginning the night of May 13. Gutierrez, who had worked for the family for 20 years, said in an interview that the messages left her with the impression that something was amiss with her employers. 
 
 She said that on May 13, Savvas Savopoulos had asked her not to come to the D.C. home the next day — the day of the killings — even though she normally worked there on Thursdays. Instead, he told Gutierrez that he preferred her help the following day with the grand opening in Chantilly. 
 
 Gutierrez said Savvas Savopoulos left her a voice mail on May 13, saying that Figueroa, the housekeeper who was killed, planned to stay overnight at the family’s home, which she described as unusual. He said in the message that Amy Savopoulos was ill, that Philip was recovering from a concussion and that the family needed Figueroa’s help. Savvas Savopoulos asked Gutierrez to let Figueroa’s family know not to expect her. 
 
 Gutierrez said she didn’t hear the voice mail until the morning of May 14. She called Amy Savopoulos and got no answer. Just before 10 a.m., Gutierrez said, she got a text message from Amy Savopoulos: “I am making sure you do not come today.” 
 
 Gutierrez said that she knew nothing about the money that was dropped off May 14 and that she had never seen the assistant or anyone else drop off cash to the Savopoulos home in the 20 years she had worked there. 
 
 On May 15, the day after the killings, the personal assistant called the veteran American Iron Works employee’s cellphone “and was crying,” according to the police documents. The assistant “stated that he had dropped off a package” at the Savopoulos house on May 14, on his way to Chantilly, the documents say. 
 
 Little could be learned about Wint late Wednesday, and it was unclear whether he had any previous connection to the Savopoulos family. Authorities offered a reward of up to $25,000 for information leading to his arrest and conviction, and asked that anyone with information about the case call police at 202-727-9099.

– Whoever killed four people in a DC mansion appears to have gotten away with at least $40,000 in cash. The Washington Post reports that an assistant to businessman Savvas Savopoulos dropped off a package with that amount at his home last Thursday while the family and a housekeeper were being held captive. It's not clear whether the assistant knew the package contained money, why he dropped it off, or whether he had any inkling that anything was amiss. Hours later, the mansion was in flames, and firefighters found the bodies of Savopoulos, wife Amy, their 10-year-old son Philip, and housekeeper Veralicia Figueroa. Investigators think the four had been held for about 10 hours. In fact, WUSA9 reports that two Domino's clerks say a delivery person brought a pizza to the house at some point during that stretch. The station is floating the theory, based on an anonymous source, that the killers coerced Savopoulos into coming up with money. Authorities haven't said much about how the victims died, only that three had wounds. DC police chief Cathy Lanier says detectives are "passionate" about the case, particularly because Philip was only 10. One of the few public clues is an image of a hooded figure running.
