Not just in our case but also in the Bristol county case which he will likely be tried forests. For these reasons. We must be limited in the information that we released to the public outside of the court proceedings. Discuss these limitations with commissioner Evans and he agrees with me -- the -- of the heightened -- public interest in this case. On the morning that -- annual day of -- who and so Ferrell for -- what killed. They were described in media reports is being tied to a -- -- and gang based in Dorchester. Nothing could be further from the truth. Neither of them were involved in gangs. Guns all violent crime of any kind. And that characterization was unfit to be a memory. And their families. We have only the deepest sympathy for them and full of their -- deals. At about 12:30 AM on July 16 2012. The victims arrived at the cure cure lounge on from one street in Boston's theater district. By coincidence. Aaron Hernandez. And another individual. Entered the club at the same time. Our investigation has not uncovered any evidence that these several individuals were known to each other. But their chance encounter inside the club. Triggered a series of events that culminated. In these murders. After the victims left the club at approximately 2 AM they drove down from -- street.

And the recovery of the murder weapon from an individual. With ties to Hernandez. Expect more information will be forthcoming at the arraignment. But at this stage of the case the return of the indictments there are limitations the information that I can provide. -- to the indictment returned against Hernandez cousin -- Singleton. She was subpoenaed to testify before the grand jury investigating. These murders. She was granted an order of immunity to provide certain information. Regarding the SUV used in those murders without exposing herself to criminal prosecution. But instead on September 13 2013. She refused to testify. The depth and breadth of our investigation speaks to the professionalism of our trial and investigative team. First assistant DA had -- Let the investigation Ferrara office and a quality -- -- -- who was just. I would also like to command sergeant detective Mark Sullivan and his squad. They proved -- commitment to this case on the word attracted national attention. The outstanding work they did collecting. Preserving. And analyzing the -- And those critical first few days contributed directly to the extensive progress we may -- In the grand jury over the past year. I would also like to thank the Massachusetts state police and -- Attleboro police. The Bristol and Hampden county district attorney's offices. The Bristol county state police detective unit and police and prosecutors in Hartford in Bristol Connecticut. In the United States Marshal service -- assistance in the course of this investigation. For -- this case was never about Aaron Hernandez. This case was about two victims were stuck. Ambush and senselessly murdered. On the streets of the city they call it. -- sign this case. The first assistant DA had taken the very morning these murders not because we knew with the evidence would take us. But because it was a brutal double homicide. With few leads and well suited to his -- as a prosecutor. 88 Anderson responded to the client of Shawmut avenue and Harold street along side -- detectives told -- his squad that early morning. She has been involved with this case since that time. Again not because of -- the defendant turned out to be but because the victims and their families -- our very best efforts from -- one. No matter who the victim of the defendant might be every murder in Boston gets the very best investigators. And the most experienced prosecutors. Again. I know that you have many questions probably very detailed in fact this specific questions. That we simply cannot ethically answer at this stage of the process. In a week -- so. When the man who pulled the trigger the honor of Shawmut avenue -- Harold street is a range in the Suffolk Superior Court. I expect that you'll hear -- much more about the facts and the circumstances of this case but for the moment. I must ask for your patience as we proceed carefully and methodically. As we have since that terrible morning in July of 2012. Now ask commissioner William Evans. If you -- -- district -- game. Again. You know. Go to the families -- this. You know if it was a terrible tragedy is being he's confident this isn't -- -- that it can count. We have two young men out. At the nightclub Cuba and -- it and basically I'm. You know happening countdown that led to obviously -- -- and and that's the tragedy here. As -- I think all the time when we have. Phillies in the city and the one right away thanks -- gang activity -- went too young innocent victims. We'll show loved ones can. Never -- -- thinking about them whose life's work. -- taken way too early. That -- entrapment that morning and that we're going into the scene that morning and you know it was a terrible tragedy I just want to stress my father said.

You know will work hand in hand with them and -- and currently -- staff and together. We pulled this together. And and it's a good day for the prosecution. But again it's still a terrible tragedy for the family and like the DA says. You know we can go -- mourn teen killed on the arraignment that.
