TV Documentary on JFK Assassination Highlights Use of Leica ScanStation P20 in Shooting Scene Reconstructions

7 November 2013

Leica ScanStation P20 is used to recreate and analyze the crime scene and possible bullet trajectories as part of a NOVA documentary that re-examines the evidence using modern scientific tools.

(Heerbrugg/Switzerland, 7 November 2013) - What really happened in Dealey Plaza in the West End district of downtown Dallas, Texas, on Nov. 22, 1963? Did Lee Harvey Oswald, acting alone, fire the bullet that killed President John F. Kennedy and wounded Governor John Connally? Or were additional shooters involved as part of a larger conspiracy?

On Nov. 13, 2013, the NOVA documentary COLD CASE JFK will follow a group of experts who re-examine some of the unsolved mysteries of the Kennedy assassination using modern scientific tools. Among the group is Michael Haag, a forensic scientist with a major southwestern law enforcement agency and an independent forensic science consultant specializing in shooting scene reconstructions.

As part of the investigation, Haag traveled to Dealey Plaza where he was joined by Tony Grissim of Leica Geosystems, a technical advisor for the Association of Firearm and Tool Mark Examiners. Using a Leica ScanStation P20, the team spent an entire day collecting laser scan data from the plaza and from inside the Texas School Book Depository (now known as "The Sixth Floor Museum at Dealey Plaza") where the shooting is said to have taken place.

"With the scan data, once you go in and start either putting yourself in a particular viewpoint or taking some of those measurements, it's pretty easy to begin knocking some of those [conspiracy] theories down … or see what is possible," Haag said in an interview with Leica Geosystems.

"Cold Case JFK" will air on Nov. 13, 2013, at 9 pm ET on PBS as part of a series that commemorates the 50th anniversary of President John F. Kennedy's death. Watch the preview here: http://video.pbs.org/widget/partnerplayer/2365105347/
