Federal agencies arrested a former Selma postal carrier and Orrville contract driver Friday for allegedly distributing drugs while on the job.

Former postal carrier Nakia Johnson and contactor Kizzy Stallworth Simmons were arrested April 8, according to postal inspector Tony Robinson.

“States like Colorado and other states have legalized marijuana. What that does not legalize is sending marijuana through the mail. It’s still a federal offense,” Robinson said.

Johnson and Simmons were both charged with conspiracy to distribute marijuana and possession with intent to distribute marijuana and will be prosecuted in the U.S. Southern District of Alabama in Mobile.

U.S. Postal Service Office of Inspector General assistant special agent Jeff Krafels said Johnson was relieved from his duties on Jan. 2.

“It looks like this was definitely an ongoing thing, and it wasn’t indicted until later,” Krafels said. “Administratively, we handled that part of it.”

Simmons, although not a USPS employee, will still be charged federally.

The United States Postal Inspection Service offers rewards up to $50,000 for information leading to the arrest and conviction of any persons mailing illegal drugs, controlled substances or any cash proceeds from the sale of illegal drugs.

According to USPS.com, the U.S. Postal Inspection Service makes roughly 1,000 arrests each year for drug trafficking and money laundering cases.

Robinson said Simmons had been under investigation since October and are two of the more recent cases in Alabama.

In August 2015, authorities arrested and charged two postal workers and two alleged drug dealers in Tuscaloosa for participating in drug distribution after nearly a year of investigation, according to AL.com.
