Democracy Dies in Darkness THE BLAST EFFECT This is how bullets from an AR-15 blow the body apart Editor’s note: We are publishing these 3D animations to show the destructive power of the AR-15. The images may disturb some people. The wounds show the lethal force of the AR-15. But they are rarely seen. The gun is the weapon of choice for many mass killers. It works with brutal efficiency.

The AR-15 fires bullets at such a high velocity — often in a barrage of 30 or even 100 in rapid succession — that it can eviscerate multiple people in seconds. A single bullet lands with a shock wave intense enough to blow apart a skull and demolish vital organs. The impact is even more acute on the compact body of a small child. “It literally can pulverize bones, it can shatter your liver and it can provide this blast effect,” said Joseph Sakran, a gunshot survivor who advocates for gun violence prevention and a trauma surgeon at Johns Hopkins Hospital. During surgery on people shot with high-velocity rounds, he said, body tissue “literally just crumbled into your hands.” The carnage is rarely visible to the public. Crime scene photos are considered too gruesome to publish and often kept confidential. News accounts rely on antiseptic descriptions from law enforcement officials and medical examiners who, in some cases, have said remains were so unrecognizable that they could be identified only through DNA samples. As Sakran put it: “We often sanitize what is happening.” The Washington Post sought to illustrate the force of the AR-15 and reveal its catastrophic effects. The first part of this report is a 3D animation that shows the trajectory of two different hypothetical gunshots to the chest — one from an AR-15 and another from a typical handgun — to explain the greater severity of the damage caused by the AR-15. The second part depicts the entrance and exit wounds of two actual victims — Noah Pozner, 6, and Peter Wang, 15 — killed in school shootings when they were struck by multiple bullets. This account is based on a review of nearly 100 autopsy reports from several AR-15 shootings as well as court testimony and interviews with trauma surgeons, ballistics experts and a medical examiner. The records and interviews show in stark detail the unique mechanics that propel these bullets — and why they unleash such devastation in the body. This is a .223-caliber-sized round inside an AR-15. What makes the weapon so deadly is the speed of that bullet. It is small and light. Its cartridge holds enough propellant to send the bullet flying out of the barrel at a speed that would cross six football fields in a second. This is a 9mm-sized round, a common choice in handguns. Its bullets are larger, inside smaller cartridges. They don’t hold enough gunpowder to match the velocity of the .223. Any bullet can kill, and instantly, when it hits a vital organ. The higher speed of a bullet from an AR-15 causes far more damage after it hits the body and drastically reduces a person’s chances of survival. “As that bullet slows down,” said trauma surgeon Babak Sarani, an authority on casualties from mass killings, “that energy is so massive it has to go someplace, and your body will literally tear apart.” In this hypothetical scenario, the bullet bursts into the chest cavity. It shreds lung tissue, severs nerves and vessels and causes massive bleeding. It also begins to tumble, taking a chaotic path in the body. The speed at impact creates a blast effect, like the wake that follows a boat, causing internal injuries far outside the bullet’s path. Here, the blast destroys large veins that carry blood back to the heart. A 9mm bullet from the same distance takes a relatively linear path. Because that bullet doesn’t produce the same blast effect, it causes far less damage. The bullet from the AR-15 leaves behind a gaping exit wound. The 9mm bullet fired from the handgun has a much smaller exit wound. In this scenario, with immediate medical care and minimal bleeding, the victim has a chance at surviving the 9mm shot to the chest. The bullet from the AR-15, however, causes torrential bleeding that is quickly lethal. Two children, many bullets When multiple bullets from an AR-15 strike one body, they cause a cascade of catastrophic damage. This is the trauma witnessed by first responders — but rarely, if ever, seen by the public or the policymakers who write gun laws. The Post determined that there is a public interest in demonstrating the uniquely destructive power of the AR-15 when used to kill. What follows is a detailed depiction showing the impact of bullets fired from AR-15s at two young victims. It is based on autopsy reports for Noah Pozner and Peter Wang that The Post obtained through public records. Due to the unusual visual nature of the presentation, The Post took the added step of seeking — and receiving — the consent of the victims’ families before proceeding with this account. The Post offered the families the opportunity to view the depictions in advance of publication, which they declined to do. The families also declined to be interviewed for this story, but a spokesperson for the Wang family offered a statement explaining why Peter’s parents, Hui and Kong Wang, provided their consent to The Post. “Peter’s parents want people to know the truth,” said Lin Chen, their niece and Peter’s cousin. “They want people to know about Peter. They want people to remember him.” This presentation may be disturbing to some people. Letter from the editor: Why we are showing the impact of bullets from an AR-15 on the human body (Family photo) Noah Pozner, 6 Newtown, Conn. Noah was found dead on the floor of Classroom 8 at Sandy Hook Elementary on Dec. 14, 2012. He was 6. He was wearing a red Batman sweatshirt, black pants and black sneakers. He loved Batman. He was full of energy, his family said, curious and imaginative. He wanted to be an astronaut, and he also wanted to manage a taco factory, because he loved tacos. Noah would tease his sisters that when they went to bed, he was going off “to his third shift” at the factory, so convincingly that they would wake up to make sure he was still in bed.

(Family photo) It was cold that morning when his father, Lenny, dropped him off at school, “but he jumped out not wearing his jacket and he had one arm in one sleeve and his backpack in his other arm, and he was kind of juggling both and walking into the school that way,” Lenny Pozner would later testify. “And that’s the last visual I have of Noah.” The first visual that Connecticut state police Sgt. William Cario has of Noah is this: 15 children and two educators are piled on top of one another in a small school bathroom on the southwest corner of the classroom. Cario proceeded to pull them out one by one. All were dead. One of them was Noah. Noah was shot three times. Adam Lanza took his mother’s AR-15 rifle to the school and fired 80 rounds into the bathroom. Here are the wounds that killed Noah. The bullet that struck Noah’s left thumb caused the smallest of his wounds. His hand was badly mangled. The bullet that struck Noah’s back crossed through the center of his chest, filling it with blood. It broke apart into fragments, according to 2019 court testimony from chief state medical examiner Wayne Carver. The bullet that hit Noah’s face caused an almost “complete destruction” of the lower lip and jaw. Noah’s wounds were not survivable, Carver testified. “This particular kind of projectile, it’s got so much energy that it just breaks up.” The pattern of metal over a wide area, he said, “would give me a marker of ... what organs were destroyed and how completely.” Peter Wang in an Army JROTC uniform. (Family photo) Peter Wang, 15 Parkland, Fla. Peter was found dead in a third-floor hallway of Marjory Stoneman Douglas High School on Valentine’s Day 2018. He was 15. He was wearing his Army JROTC uniform. He kept notes in his bedroom drawer about his plans. He had joined the military training corps, with its mission to “motivate young people to be better citizens,” as an important step toward attending the U.S. Military Academy at West Point. Peter Wang at Walt Disney World in January 2018. (Family photo) Born in New York to parents from China, he was always helping everyone around him, friends and family said. Once, at Disney World, he held a friend’s child aloft in a crowd for 20 minutes so she could see a fireworks display. When gunfire broke out at Parkland, Peter was in study hall, playing chess with a friend. He held the door open for other students to escape. A few of them made it. He did not. Peter was shot 13 times. Nikolas Cruz used an AR-15 he bought legally and fired at least 139 rounds. Here are the wounds that killed Peter. Peter was running down the hallway when he was shot. He was struck once in the foot, twice in the thigh, once in the torso, five times in his arms and, finally, four times in the head. One of the bullets that hit his thigh fractured his hipbone and then broke partially apart before exiting through his abdomen. Two bullets tore Peter’s chest apart. One entered his torso and flew upward, fragmenting and perforating his chest muscle, which bruised his lungs and created a cluster of three large exit wounds. The other struck the back of his upper right arm, pierced the shoulder joint and opened up a gaping hole on the way out. The four bullets that obliterated Peter’s head were the last four he received, medical examiner Wendolyn Sneed, who performed the autopsy, testified at Cruz’s sentencing trial last year. Surveillance video showed that Peter’s legs were moving as the killer came closer to him and fired rapidly. The combined energy of those bullets created exit wounds so “gaping” that the autopsy described his head as “deformed.” Blood and brain splatter were found on his upper body and the walls. That degree of destruction, according to medical experts, is possible only with a high-velocity weapon. Peter was one of 16 Parkland victims who were shot several times. The shooter had equipped his AR-15 with the ability to fire dozens of rounds without pausing to reload, preventing people from escaping. In many of America’s mass killings, shooters hit multiple victims, multiple times. In seconds. You have been on this page for 7 minutes and 6 seconds. It took approximately 8 minutes for the shooter to kill 26 people including a pregnant woman and injure 21 others at a Sutherland Springs, Tex., church. About this story Reporting by N.

(Twitter/Morgan Marchand/Storyful) Students raise their hands as armed law enforcement officers enter a classroom at Marjory Stoneman Douglas High School in Parkland, Fla., in 2018 (Alexander Ball/Storyful) The models and animations were constructed from academic research reviews, interviews, autopsy reports and other records The Post obtained, in consultation with the following: Babak Sarani, director of trauma and acute care surgery at George Washington University Hospital; Joseph Sakran, vice chair of clinical operations and a trauma surgeon at Johns Hopkins Hospital; Cynthia Bir, chair of biomedical engineering at Wayne State University; and Victor Weedn, deputy medical examiner for Washington, D.C. The Post relied on post-mortem and autopsy reports and medical examiner testimony at trials to illustrate with precision the entrance and exit wounds that were identified in the bodies of Noah Pozner and Peter Wang. The depictions are as precise as could be determined from the records, which included the medical examiner’s hand-drawn diagrams for Peter. Those documents do not detail the position the victims were in when they were struck, or the full sequence of the bullets and their precise path through the body. The calculation that a .223 round fired from an AR-15 can reach speeds of up to six football fields in a second was made using a 55 grain .223 Remington full metal case round fired at a horizontal trajectory. The muzzle velocity of this round is 3,240 feet per second. This estimate accounts for drag as the bullet slows down over distance and time. It does not account for weather or other interference. Nor does it account for horizontal drop as the bullet would probably hit the ground before reaching six football fields. The Post consulted with mechanical engineer John Greenawalt and Cynthia Bir, chair of biomedical engineering at Wayne State University. Ten of the 17 deadliest U.S. mass killings since 2012 have involved AR-15-style guns. (Handguns are involved in the bulk of U.S. gun homicides, responsible for 90 percent of cases in which the type of firearm is known.) The Washington Post defines mass killings as a shooting event in which at least four people are killed, not including the gunman. The timer at the conclusion includes 10 mass killing events that involved AR-15s. The time elapsed from the first shot to last were all under 11 minutes. That timing is approximate and based on official reports and news reports.
