four people in this house all through wednesday night. the housekeeper spoke with me the same day these four bodies were found on thursday and told us normally she would come work on thursday, but she received an odd text from the wife who lived there, amy savopoulos, telling her not to come in. >> i start calling her and say -- and left her a message that asking her that she was okay and she never answered. >> reporter: days later she said that wasn't the only message she got from the family. savvas savopoulos left her a voicemail wednesday night. >> but i never got that message the same night. i got it the next day. >> reporter: in that message he told her not to come in the next morning, that the other housekeeper, veralicia figueroa, was staying overnight to help out because amy was sick. that was not normal. >> they offer to stay overnight is not normal because she never

stayed in that place overnight, but i never got that message the same night. >> reporter: veralicia's husband thought it was strange as well so, strange that he called savvas and drove to their house thursday morning, but he says no one answered the door. a nearby domino's says they delivered pizza to the house and a manager tells me police came by the store friday and asked for a record of all of the order and deliveries from wednesday night. now police documents obtained by our editorial partners at the washington post say one of savvas' assistants told police he dropped off a package at the house on thursday. law enforcement sources tell us that package had $40,000 in it, but the most horrific information coming from law enforcement sources is that during this time the couple's 10-year-old son may have been tortured. sources tell our bruce leshan that phillip is the only one without stab wounds and they believe he was burned and tortured in front of the family to get money from his father.

so many clues point to the family being held in this house overnight. one rumor we are hearing is perhaps there was dna on one of those pizza crusts left behind by the killer and police may have been able to use that to at least identify this suspect. that detail hasn't been confirmed. in fact, most of these details are things police won't officially comment on. this is ongoing and they don't want to comment on investigations, but again there's a luge break tonight the police identifying a suspect, his name daron wint and he's 34 years old. ellison barber, wusa9. >> things are moving very quickly. the man's name is daron dylon wint. he's 34. a cold rain is on the way for tomorrow. >> the wet weather could affect not one but both of your commutes. first alert chief meteorologist topper shutt is here. it's yellow alert time.
