Starting in the mid-1990s, Capt. Dan Cummings worked as an undercover cop going after meth suppliers in his hometown of Independence, Missouri.
He had grown up seeing what meth could do, so for him the work was personal.
“When I was a kid, a cousin brought a bag of this white powder in and said, ‘Man, hey, you gotta try this stuff. Man, you can go forever,’” Cummings says. “He did. He’s now passed on.”
