What Really Happened the Night Hollywood Power Publicist Ronni Chasen Was Killed?

Six years later, her best friends still feel no sense of closure, and now newly released documents raise serious questions about a flawed investigation.

Exactly what happened after Chasen, then 64, left the W valet for home in her black 2010 Mercedes-Benz E350 remains unknown. This much is clear: At about 12:28 a.m., four shots were fired through the vehicle's front passenger window as it likely slowed or stopped in the left-hand turn lane heading west on Sunset to make the turn south on to Whittier Drive, a residential street where homes cost as much as $25 million.

ClaimsLogo.jpgNew Tools for Reconstruction
Computer generated 3D animations are being used widely to demonstrate to jurors what an expert has determined occurred during an accident or crime. A 3D animation presents technical and complex information in a clear and compelling way, which enables the entire jury to see the facts of the case as the attorney and expert believe that they occurred.

New Tools For Crime Scene Reconstruction
Forensic experts can now accurately reconstruct crimes because of the development of high-speed laser scanners. Previously impossible or prohibitively expensive reconstruction can now be done using laser data. The high-speed laser can develop one million measurements of a crime scene in 12 minutes with an accuracy of plus or minus one-quarter of an inch!

PSI's Craig Fries testified in the high profile federal civil rights trial against the city and county of San Francisco for the fatal police shooting of Alejandro Nieto in 2014.

Four San Francisco police officers who shot and killed a 28-year-old man in Bernal Heights Park two years ago did not use excessive force, a federal jury has ruled.

The verdict was delivered early Thursday afternoon in federal court, less than a day after closing arguments concluded in the wrongful death suit filed by the family of Alex Nieto against the officers and San Francisco.

Caught in the act! Accident reconstruction from captured video footage can prove more than you might think.
Your client has suffered serious injury in a vehicular accident. Liability is not clear, and there is a lack of physical evidence left at the scene – no skid marks, not solid witnesses and very little to build a foundation for the reconstruction of the event.

Cutting Edge 3-D Reconstruction From investigator to juries, forensic animation gives accurate reconstruction
The introduction of high speed laser scanning has greatly increased the accuracy and realism available to the forensic animator. Combining this accuracy with laser-assisted photogrammetry is enabling experts, working closely with forensic animators, to accurately reconstruct events that would have been impossible or financially prohibitive, a few years ago.
