Verdict: Guilty of First Degree Murder - Dateline NBC in Quincy California for Wallin-Reed Trial

NBC broadcast a special two-hour Dateline segment about the murder case to a national audience on Friday, Oct. 18, at 9 p.m.

Keith Morrison and a team of NBC producers began researching, shooting video footage and conducting interviews in June.

PSI’s CEO, Craig Fries, testified to the 3D reconstruction and 3D Laser Scanning Analysis that showed that the victims were attempting to flee from their assailant at the time they were shot. Plumas County District Attorney David Hollister used the 3D graphics extensively in his closing.

Case Study Preview

Get a sneak preview of our next three Case Studies, make sure and check out these challenging and interesting scenarios.

August 2013, Vehicle Crush Analysis
In the analysis of vehicle accidents, one of the most important sources of insight is the physical evidence left behind in the form of vehicle deformation, often referred to as “crush”. The amount and location of the damage to the vehicles exterior and interior provide the reconstruction expert with detailed data regarding the energy expended in the collision.

The Second Annual Defense Counsel Summit, August 15, 2013, Martinez CA. Featuring Special Guest Speaker, Craig Fries.

May 2013, The Need for Measurement, Not Conjecture! 
Forensic reconstruction of vehicle accidents begins and ends with data. The accuracy, fidelity and ultimate validity of the reconstruction is limited primarily by the quality of the data available.

February, 2013 - PSI Acquires RaceLogic VBox 3i
PSI is excited to announce a powerful new addition to our Forensic Engineering Toolset – The RaceLogic VBox 3i 100Hz system with Dual-Antenna GPS. PSI’s  VBOX is a state-of-the-art vehicle dynamics measurement system, allowing the real-time measurement of forces on a vehicle, including Speed, Acceleration, Braking, Lateral forces, Slip/Yaw, Pitch and Roll. The system also logs the position of the vehicle over time via its synchronized accelerometers and Dual-Antenna GPS, and can be mounted on commercial vehicles, passenger vehicles, motorcycles and even bicycles.
The result? The most accurate, valid and highest fidelity vehicle reconstruction data available!

January, 2013 - PSI Upgrades to Leica Geosystem's ScanStation C10
PSI is proud to announce the acquisition of our new 3D Laser Scanning System - The Leica ScanStation C10. The Leica ScanStations blazing fast data capture (50,000 points/second) and unparalleled accuracy (Typical registration to within 0.001m) allow PSI to document any scene or object in 3D with the highest possible fidelity.

Pinasco

On August 24th, 2008, CHP Officers Walling and Coffman were led on a hi-speed pursuit in the outskirts of Stockton by Joey Pinasco. The pursuit ended on a little-used dirt road when Pinasco lost control of his Chevy pickup and swerved into a drainage ditch. After giving verbal commands to Stop! Show me your Hands! Officer Coffman positioned himself near the front of the Chevy and Officer Walling approached the Chevy and knocked on the window. At this time Pinasco pressed the accelerator and began spinning his tires and heading towards officer Coffman, causing both officers to discharge their firearms, killing Mr. Pinasco. Mr. Pinasco’s family sued the State for Violation of Mr. Pinasco’s civil rights and negligent homicide.
