People who worked with Ronni Chasen tell TMZ ... video of the woman pulling out of Ronni's condo building on October 28 is not her.
A private detective who was surveilling Ronni's building that day claims to have a video (screen grab above) which shows Chasen.
We have forwarded the video on to Beverly Hills detectives, but no word from them on their analysis.
Ronni's co-workers say she was not in L.A. on October 28.
