trauma, striking these poor people on the back of the head. a knife is discovered in the trash behind the house. police find fingerprints and hair fibers. >> that would establish a direct linkage between a suspect or an individual and the crime scene. >> police find duct tape believed to have been used to restrain the victims, and matches thought to have been used to start of fire. and then the family's porsche missing from the garage, found 13 miles from the mansion, engulfed in flames. inside the burning car, a green construction vest, similar to vests worn by workers at savvas' company, aiw. >> was it some part of ruse, that the offend onners came in as a representative of a utility company, trying to get access to the house? >> later that vest will provide another critical clue.

the mystery deepens as police find thousands of dollars of cash left behind in the house. why would the killers level money behind? >> it was not just about the money, it was not just about all the jewelry that probably was there. that really goes to the motivation of the offender, that these murders themselves were very important. >> and the autopsies show the murders were horrific. >> they had to be restrained, or else they couldn't have been tortured and treated the way they had. they would have fought back. mr. savvas savopoulos was a healthy young man, 46 years old. he certainly would have fought back if he had not been restrained. >> even after the ransom money was dropped off, the horror continues for several more hours, until the house is set ablaze in the early afternoon. >> the subjects probably administer additional pain for

the victim, that gap of time is i want more, you can get more. >> savvas and vera were beaten, stabbed and strangled. >> that's a very close-in injury. it's not like a gunshot where you can shoot a gun from a distance. this strangulation, you have to be right in and at your victim. there's a psychological overlay here to what's going on in that home. >> amy died from sharp force trauma, and 10-year-old philip stabbed and burned beyond recognition. >> i think it became pretty clear to the first responders that the child had been tortured multiple stab wounds. the son was engulfed in flame, to the point where the body was so charred that these couldn't even determine gender.

>> first responders find the three adults in a bedroom upstairs, vera and amy bound in chairs, and savvas on the floor. >> the 10-year-old was handled separately. >> philip is discovered in his bedroom, alone. >> he was the bargaining chip, the threat was made against him while getting the adults to do whatever the perpetrator wanted. >> the unknown of where is my son? i want to see my son or whatever pain and suffering he was going through, it's all in the mind of a killer. >> clearly this is where the fire started. philip's bedroom where his body was found. why do you think they started the fire there, which could easily be seen on the street. >> i think this is a mistake of a killer who is not particularly organized, a killer who thought

that the use of an accelerant, gasoline presumably would burn faster, hotter and more completely. >> but the killer's assumptions were wrong. >> this resulted in the potential discovery of much physical evidence that could be preserved, tested, people eliminated, people included in the suspect hunt. coming up, an unexpected clue breaks the case wide open. >> that looks like the pivotal piece of evidence.

in court, wint's lawyers argue their client could not possibly have acted alone and raise questions about savopoulos's assistant, 28-year-old jordan wallace who delivered the $40,000 to the mansion as the victims were being held hostage inside. police say wallace, who had only been working for savopoulos for a couple of months sent a picture to have a friend showing two bundles of cash inside a red bag but four bundles were taken from the bank. >> where are the other two? this is before the drop was ever made. isn't that interesting? >> and court records show in wallace's backpack, his passport, checkbook and the registration for one of savopoulos's sports cars valued at more than $300,000. >> what disturbs me is that his passport was present in the bag. what does that tell you? i don't carry a pass portland around with me. was he going to fly?

leave the country? escape? i think the police are very curious about mr. wallace. >> and could there be a connection between jordan wallace and darren wint? our research shows in 2006 wint lived in the same maryland apartment complex as wallace's father. >> i don't think that's a coincidence at all. i think that's very strong evidence that the two very likely ran into each other and knew each other. that very likely was the place where these two men first met. >> what's still not clear is if jordan wallace actually nifd in the same building as wint or just visited. and we found no other indication wint and wallace knew each other. >> i'd say five years the technology has been there especially in the electric ga carts. >> callous, a race car enthusiast, raced suspicions early on because investigators say he changed his story several times about the money drop. >> are these inconsistencies

based on his being nervous with all of the story about quadruple homicide and him as the delivery person, does the excitement and the risk of his involvement in that case play with his memory? is it all innocent? >> have you seen this before in other cases? >> sure. sure. and it happens in high pressure cases and certainly here the pressure is on because four people are dead. >> despite their suspicions, police have not found any hefd implicating wallace in any of the murders and they've nod charged him in this case. cnn tried to get his side of the story but neither he nor his family would comment testimony d.c. police have been looking at darren wint's cousin who happened to work here at american iron works. he was fired around the same time wint left. and sources say the company had to take out a restraining order against the cousin because he allegedly threatened to burn the place down. though hoe has not been named a

suspect in this case and cnn has not been able to reach him for comment. why only wint? why is he the only one behind bars right now do you think? >> i don't think why he's the only one behind bars, i really don't. i'm amazed that they have not brought somebody else in. >> so many questions still linger. was revenge the motive? >> it could have been he was angry about losing his job ten years ago, he resented losing his job. >> if the motive was money, why leave expensive art, jewelry and thousands of dollars in cash behind? >> there is abelement here that seems personal. there are indicators of anger in this. there certainly are indicators of torture in this. all over a relatively small amount of money. >> i'm sure that savopoulos would have given everything away to save his family. >> and could someone have saved the family?

>> you look at opportunities for people to have called the police, to have alerted the police that something isn't right at the house, whether that's the other -- the housekeeper's husband, the other housekeeper who was waived off in an unusual way, the assistant, people at work. is this a story of opportunity lost? as family aends fren say good-bye to fill lip, amy, salve va and vera, all are left to wonder why anyone would want to hurt this family. >> we may never know the true story. >> we may never know. we may never know. >> i just picture the three of

them together, and that's the only thing that makes me feel better, is that at least they're together. ♪ it's early spring in richmond, virginia and terrance williams is an hour away from the most meaningful day of his life. >> a tie, going to look good. >> the city of richmond is hosting a father-daughter dance for terrance and 12 other dads. >> man, i feel like money. >> but there is a catch. these men are inmates of the richmond jail, and this dance will be the first time terrance's daughter, takayla, will have seen him in eight months.
