The results of this FBI analysis really reinforces the importance of shot placement if you are ever forced to use your gun against an attacker. Police fired a total of 107 rounds at the single suspect and it took an M4 rifle to finally incapacitate him. The suspect was able to fire 26 rounds from his .45 caliber handgun and even reloaded from a box of loose rounds.
3 officers were involved in a shooting this week. An ambush was set up for the officers prior to their arrival, they took fire while still in their cruisers. One officer was hit in the forearm, another received wounds to his forehead from a ricochet, another was injured (NFI). The suspect was armed with a .45 handgun. The officers were armed with Glock 22's (.40S&W) and SPEER 180 gr. Gold Dot Hollow Points.
Officers fired on the subject and hit him in the left arm, completely shattering the bone. He was also hit five times in the chest and abdomen. All rounds penetrated less than 1 (one inch) $B!m(B. All of the rounds expanded fully but did not cause incapacitation due to the lack of penetration. According to the Medical Examiner, none of the rounds caused any life threatening injuries. The subject also received one round into the front of his throat, it penetrated less than 1$B!m(B as well. The Medical Examiner stated that the recovered rounds were in pristine condition (still had rifling marks on them).
The subject was wearing a down jacket at the time of the incident. He was finally taken down after receiving rounds from an M-4 .223, with Hornady Tap 55 gr ballistic tip rounds and Hornady Tap 72 gr. Hollow Points.
The officer with the M-4 was able to shoot underneath a vehicle and hit the suspect in the ankle. The officer then flanked the subject, who continued to engage officers, and was eventually killed by the officer with the M-4.
The subject had a trace amount of marijuana in his system.
Range between subject and officers: 20 feet.
Subject had a t-shirt on under his jacket.
Subject received approximately sixteen .223 rounds, thirteen of these rounds went completely through. One round struck his hip and completely shattered it. Another .223 round struck his aorta and another pierced and collapsed his lung. Both of these rounds lodged themselves inside the subject. The Medical Examiner stated that the .223 rounds caused massive internal damage.
This is the second shooting that the PD has experienced where they had to shoot a subject in excess of ten times with .40 S&W ammo to incapacitate or kill. There was another incident where a subject was shot inside of his vehicle. He was struck approximately ten times, all the while continuing to fire at officers. He was eventually killed after suffering a shot to the back of his head.
In this same incident, the back of the subject's seat was struck multiple times, the .40 S&W rounds never penetrated through the seat. In this incident, all shots had passed through either the windshield or rear window. Investigators assume that this was the reason for the poor ballistic performance.
(The) PD is now considering replacing their Glock 22's (.40S&W) with Glock 21's (.45ACP).
Here is the FBI's PowerPoint presentation on this incident.
