Transcript for Investigation Deepens into the Philip Seymour Hoffman's Death
Isn't the internet amazing? A new development in the investigation into the death of Philip Seymour Hoffman. Police have determined one of the men arrested for dealing drugs did have ties to Hoffman and ABC's John muller with the details. Good morning. Good morning, George. Did the gifted actor buy heroin from a talented musician? Investigators now checking into cell phone records while toxicologists test specific types of heroin hoping to find out who and what are behind Philip Seymour Hoffman's death. This morning, police investigating the death of Philip Seymour Hoffman are turning their focus to this man, suspected heroin dealer Robert vineberg arraigned overnight and while police have not linked him directly to Hoffman's death they do tell ABC news he knew the actor and even had his phone number stored in his cell phone. Vineberg seen in this youtube video is an accomplished saxophone player reportedly played with David bowie and Amy winehouse. But police believe he may have turned to selling drugs recently when his musical career started to dry up. Police received a tip that Hoffman bought drugs at this apartment and arrested vineberg Tuesday night. Two other suspects at the apartment are also in custody this morning. Their lawyers calling them scapegoats. Vineberg's lawyer telling ABC news "We are very confident that there is no connection between the charges brought forth against my client and the death of Philip Seymour Hoffman." Meanwhile, officials revealing an autopsy report on Hoffman's body is inconclusive and that more testing will be needed. Overnight, this picture released of a somber looking Jennifer Lawrence returning to the filming of the final "Hunger games" film. Word that filmmakers will use digital imagery to insert Hoffman into the scenes he had yet to shoot to avoid having to drop him from the script as so many continue to mourn his death and the lights on Broadway were dimmed in his honor. All three suspects including Robert vineberg entered not guilty pleas. The heroin allegedly found in the raids, more than 300 small plastic bags' worth so far not believed to be the same brand of heroin found in Hoffman's apartment. George? Thanks very much.
