AURORA, Ill. --
New details are surfacing about the final moments before last week's medical helicopter crash, which killed four people. Investigators say a security videotape shows an Aurora radio tower's warning lights were on just as it was clipped by the helicopter. The radio station's president told the Aurora Beacon News that the tape came from a camera at an Aurora Metra station parking lot.
The crash killed three helicopter crew members and a one-year-old patient.
