Nineteen people were missing and possibly dead after a devastating explosion on Friday morning at a military explosives plant in Tennessee, officials said.

In 2017, Drug Enforcement Administration agents following the money from cocaine deals in Memphis, Tennessee, identified a mysterious figure in Mexico entrusted by drug lords with their millions: a Chinese American gangster named Xizhi Li. As the agents tracked Li's activity across the Americas and Asia, they realized he wasn't just another money launderer.
