The Kentucky State Police says investigators Thursday removed the plane's engine to examine it, and cautioned that the cause of the crash may take months to determine.
Officials with the medical examiners office have not yet positively identified the body found at the scene of the crash, and KSP says methods including medical and dental records are being used to help with identification.
Arrangements haven't been made yet to remove the plane from the crash site. KSP says there are natural barriers there that will make removing the plane difficult.
