Video: New Helmet Cam Shows Asiana Victim on Ground

A new video released by the family of a teen run over twice by San Francisco fire trucks after a plane crash shows firefighters being warned she was there.

The helmet cam -- first aired on CBS Evening News Tuesday night -- clearly shows the girl lying on the ground as firefighters walk around her. They signal an arriving fire truck to stop, and the driver is personally told she's in front of him. 

Firefighters admitted none of them actually reached down to check the teen's vitals to determine if she was alive. An autopsy later showed she was -- until she was run over by the fire trucks. 

The family filed a lawsuit against the city last week claiming firefighters were negligent and lacked proper training.
