Bryce Masters was tased in the chest for 23 seconds and dead for eight minutes. He faces a lifetime of recovery

Editor’s note: The Intercept, an online magazine dedicated to investigative journalism, published this story on June 7. Because its depth surpasses what any Kansas City media outlet has devoted to this case, The Pitch is republishing it in print this week (with minimal editing for space), in cooperation with The Intercept. Read and share the complete story, and see video, here.

The sentencing hearing began with a surprise.

Timothy Runnels, a 32-year-old former Independence, Missouri, police officer, sat at a large, rectangular defense table inside Courtroom 8B at the Charles Evans Whittaker Federal Courthouse in downtown Kansas City, Missouri, late last month. He faced up to 10 years in prison, after pleading guilty to a federal crime he had committed on September 14, 2014. Judge Dean Whipple had not yet watched the government’s key piece of evidence — a dashboard video — because he wanted to do so with attorneys present to make arguments. Today the video, which had never been played in public, would be shown in open court. Even the victim, 18-year-old Bryce Masters, had seen it only once.

As the video opened, a gray Pontiac entered the frame, and Bryce’s dad, Matt, put his hand on his son’s knee. His mom, Stacy, folded her arms, clutching a tissue. Tears began to form in both his parents’ eyes, anticipating what everyone else in the room was about to see. Unfazed, Bryce leaned his 6-foot-1-inch frame forward, his eyes focused on the makeshift projector. He knew this piece of evidence absolved him of any wrongdoing.

In the video, Runnels pulls Bryce over and approaches the car. He tells Bryce to get out but doesn’t give a reason. Bryce repeatedly asks if he is under arrest. Runnels says, “You’re under arrest. Get your ass out of the car,” and attempts to pull him out by force. He then tases Bryce for 23 seconds, handcuffs him, drags the boy’s body behind the car, and deliberately drops him, face first, onto the asphalt road. Runnels may not have known it at the time, but Bryce was going into cardiac arrest. When the loud thud of the drop boomed through the courtroom, gasps echoed. One woman looked down and covered her eyes with her hand. A man said, “Oh, my god.” A police officer with the Kansas City Police Department quickly brought his fist to his mouth, turned to the man next to him, and whispered, “Jesus.” Even those sitting behind the defendant — a few friends, his wife, his family — gasped, as if the recording revealed a truth about Runnels they had never considered.

Runnels’ Taser deployment caused Bryce to go into cardiac arrest. Assistant U.S. Attorney David M. Ketchmark argued that the length of time that Runnels held down the Taser’s trigger was an aggravating factor. One pull on the trigger sent electricity shooting out for five seconds; Runnels had held it down the equivalent of four pulls. Even so, the prosecution agreed that the initial Taser use was reasonable and within common police practice. Runnels’ crime, depriving a minor of his civil rights, occurred when he dropped the dying 17-year-old boy on his face.

Matt Masters does not agree that the Taser use was reasonable, but he agrees it was common police practice. He’s a 19-year veteran of the Kansas City Police Department, with a slew of warrior-cop credentials. He has worked on SWAT teams and has been part of Kansas City’s police narcotics unit, taking point on an estimated 1,000 search warrants during one three-year span.

After Bryce was tased, though, Matt discovered something he’d never heard in any Taser training he’d gone through — something he resisted believing, because it violated an article of faith among police officers: Tasers can kill.

More specifically, Matt learned that on October 12, 2009, Taser International, the Scottsdale, Arizona–based maker of conducted electrical weapons, released a training bulletin suggesting that officers should avoid shooting suspects in the chest whenever possible. Five years later — on September 14, 2014 — it would be difficult to argue that Runnels was unable to avoid shooting Bryce in the chest. Yet the defense’s argument for leniency was based on the claim that Runnels had acted reasonably as an officer right up to the moment he dropped Bryce on his face.

The wounds Bryce suffered from that part of the assault have largely healed. The permanent injury he struggles with every day came as a result of the Taser. Bryce’s brain was deprived of oxygen for six to eight minutes while he was in cardiac arrest. It was the Taser that almost killed him.
