BALTIMORE (WJZ) — A letter carrier and his co-conspirator pleaded guilty to conspiracy to distribute marijuana on his mail route.

Postal Route C-032 stretches from Fulton to Poppleton Streets in West Baltimore. It was William McRae’s postal route, where he would distribute drugs along his way.

Federal investigators built the drug distribution case against McRae based out of a Southwest Baltimore post office.

“We trust our US postal workers, if you don’t trust anybody else,” Don, a Baltimore resident said.

“I wouldn’t think you jeopardize a job like that. I wouldn’t,” Jimmie Carter, a Baltimore resident said.

His accomplice, Michael Gray, pleaded guilty on Monday.

Federal officials said McRae delivered more than 100 kilograms– 220 pounds– of marijuana on his route.

According to court documents, investigators spotted McRae passing a package to Gray on his route in January 2018 on the corner of W. Lombard and Mount Streets.

Ten months later, surveillance was set up at the Franklin Station Post Office and on McRae’s postal route, where the feds caught McRae passing two kilograms of pot to Gray.

That’s when they were arrested. More at CBS Baltimore
