Deadly plane crash in Florida came from Austin

Parts of a business jet appear to have broken off before the aircraft crashed in southern Florida, killing all nine people on board. Federal investigators are looking into what caused a small jet to nosedive into the ground Sunday afternoon. Fox's Jonathan Serri has more on this developing story. NTSB investigators are on the scene in South Florida one day after a small jet plunged into the ground in a Palm Beach County neighborhood, killing all nine people on board. The agency's GO team says it won't speculate on the cause of the crash, but adds weather conditions will be a major focus of the investigation. We do have... Some indication that the aircraft was breaking up before impact. We may find parts of the aircraft some distance away from the actual impact site. The Learjet 60 had taken off from Austin, Texas on its way to the Bahamas when at 35,000 feet, the pilot reported moderate turbulence and ice accumulation on the plane. Air Traffic Control granted her request to ascend another 2,000 feet, but within seconds received this distress call. 722 Bravo Delta, we're descending 8,000. Mayday, mayday, we're descending 10,000 feet per minute. November 722 Bravo Delta, roger. Declared emergency. Less than a minute later, controllers lost contact with the plane, which went nose down on the side of a major road. First responders evacuated some 600 residents from a nearby mobile home park and took them to nearby shelters. We have specialists from our Office of Transportation Disaster Assistance on scene. They will be working closely with the families and local agencies to provide support to those involved. The NTSB is asking any witnesses with photos or videos of the crash to contact the agency.
