Heroin, today, is killing more and more people in rural America.
One Mexican cartel has seeded low-cost heroin around rural towns in the Southwest and Midwest, selling it cheap and easy, almost like pizza.
Madison, Neb. — population 2,500 — is just a speck of a town, a two-hour drive from the big-city bustle of Omaha. But it's not far enough away to avoid the growing impact of heroin.
"The world's gotten smaller," says Police Chief Rod Waterbury. "If drugs can make it to Chicago, they can make it here."
