The manhunt for that suspect in a chilling murder case in the nations capitol that has captured the country. He has been identified by all things a pizza crust left at the crime scene. Nbcs National CorrespondentPeter Alexander is covering this story for us. Peter, this is a major break. Good morning to you. Reporter savannah, exactly right. First the murders, now the manhunt. A ton of new information for you this morning. Police are looking for the 34yearold suspect Darren Dylan Wynn who you know is connected to this scene by pizza crust. Police went to the last known arrest of the man at a home here in d. C. Its in morale. But significantly, its near to where the familys car was found burned exactly a week ago. Now the manhunt has intensified. This morning washington, d. C. Police say this man is suspected in the brutal killings of the savopoulos family and their house keeper a week ago. They are asking for an arrest or Darren Dylan Wynn. A break in the case at the nations capitol came after police found his dna on the crust of a domino pizza. The announcement came after a source close to the family said hours before the fire his assistant delivered 40,000 cash to the home. The money from american iron works where he was ceo. They report savopoulos asked his assistant to deliver the cash. Use caution. This is a crime scene. Reporter when firefighters arrived at the house thursday afternoon, investigators say the 40,000 was gone so was the familys porsche later found abandoned and torched 15 miles away. Its unclear whether wynn the person of interest seen in this under Surveillance Video running away from the car fire. They say wynn has been arrested numerous times. Overnight, crime scene investigators searched the home for blood stains. Sources familiar with the investigation say the fire began on the 2nd floor in tenyearold philips room. All three of the adults were found down the hall in a separate room beaten and stabbed. And again this morning, our local station wrc is reporting that Police Believe wynn left the immediate washington, d. C. Area shortly after those murders took place a week ago. Throughout this investigation, verts told us they believe there with may have been more than one person involved in these murders.

Lets turn to nbc news Law Enforcement analyst, a retired atf special agent in charge. Jim, good morning to you. I have to say, this is extraordinary that investigators were able to find this suspect say say from dna on a pizza crust of all things. Right, savannah solid police work by the d. C. Detectives. They poured their resources on it. They were backed up by atf fbi, lab, now they got the suspect. So the whole suspect changes. Hes a criminal actor. He tends to go to florida, caribbean, cash and he wont be free long because his picture will be all over the National Media and soeshlg media. Anybody he is in contact, savannah even a person hes known a long time will be in danger. This man is a very very dangerous man. You say its unusual to put a name and suspect to the police have identified. Wherever he has gone, they will be able to find him . Right. You know the greatest Intelligence System in the world is americas broadcast, radio, print media followed by our social media, so nobody is going to get away when their picture is all over like that. Hes a guy paying cash. Hes not likely in his home environment. He will be in a hotel. He will be paying anything for cash with this 40,000 that he brutally murdered the family with. You know hes a guy that likely had some contact with mr. Savopoulos somewhere. Maybe in the martial arts arena. Hes a pretty buffed out guy. There may have been contacts there. He likely had a help from a confederate, if they are alive. One can kill the other in a crime this huge. Its obviously a brutal development in this case. Always goed to talk to you. Appreciate it. Thanks, savannah. Meantime an oil spill is now worse than expected. As much as 105,000 gallons may have leaked near Santa Barbara. Hal le jackson is on one of the beaches.
