Eyewitness News has also learned that police are in possession of a second surveillance tape taken the night Chasen died.
She crashed her Mercedes-Benz in Beverly Hills in November after being shot five times in the chest.
The crash was captured by a surveillance camera at a nearby house.
The homeowner said the video shows a black Lincoln Town Car drive by Chasen's car just seconds after Chasen crashed.
He said it does not show the car's license plates.
