A fifth deputy put Booker in a headlock just as the female deputy began shocking him with a Taser with encouragement from one of the deputies, who kept repeating, "Probe his ---," Maten said. He could hear the Taser crackle repeatedly. Booker said, "'I can't breath...," Yedo heard. Then, Booker went limp.[LINK]
He never moved again.
Tasered. Can't breathe. Dead. A very familiar pattern.
To be fair, the news report also mentions "headlock". It's either the taser, or the headlock, or a fairy tale of coincidental death from unrelated pre-existing conditions.
