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.

“100,000, I mean, how would you even do it? Through packaging?” said Baltimore resident Carissa Jessop.

Several of the packages were addressed to apartments across from Hollins Market, but never made it there.

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.

“He didn’t drop none at my house and I don’t know why,” Carter said laughing. “I mean, c’mon, that’s not right,”

The plea agreement showed McRae was paid in cash and marijuana.

“I’m just shocked. I mean, that’s– I know the US mail was doing bad, but I didn’t know it was doing that bad,” said SW Baltimore resident Tony Stevens.

“It’s deplorable. I think they ought to do an investigation throughout the whole division. If it’s coming in through one post office, it’s a good chance it’s coming in through another,” Don said.

McRae, the postal worker, could get up to 40 years. His sentencing is July 15.

Gray faces 20 years. His sentencing is in September.

Baltimore City State’s Attorney Marilyn Mosby announced earlier this year that her office would end prosecuting cases of marijuana possession.

Her policy has no effect on federal cases, however.
