The Gulf War's rapid-fire ballistics were televised in real time.
Investigators said they found evidence of a fire and ballistics from the scene.
Far from being the work of a single expert, the E.A.A.F. had assembled a multidisciplinary group of experts in fire, anthropology, archeology, criminology, ballistics, botany, entomology, odontology, anatomy, genetics, and analysts of satellite imagery and photography.
They left Nell by the fire, walking off thirty paces, arguing ballistics as they searched for an angle where they weren't likely to get themselves killed by ricocheting bullets.
A more sophisticated understanding of forensic science has enabled lawyers to dispute expert testimony that was once taken as gospel, on matters ranging from ballistics and fingerprints to fire investigation.
Sgt. Jeff Jensen of the Colorado Springs Police Department said weapons recovered here allowed for a positive ballistics match with rounds fired in Arvada.
Explaining that, himself, he hated guns, he took the producers into an anteroom containing a ballistics tank, where he fired a Smith & Wesson.38 into the water four times, very loudly, then fished the bullets out and showed how they had been marked by the gun's barrel.
Having the two weapons fired directly at each other through ballistics gel, the artists created both a beautiful, violent slow-motion film, and a series of sculptures featuring explosions frozen in time as kinetic memories.
Mr. Jackson added, "As to who fired or the number of shots fired, we are awaiting the results of the ballistics examination".
Ballistics tests identified the gun fired that night, but it was covered in multiple DNA matches, making it impossible to connect to one person.
The fatal bullet most likely came from the police; ballistics tests revealed it was fired by a semiautomatic weapon, the type of gun used by the four officers involved in the shooting.
