A federal grand jury indicted 20 people accused of being involved in a drug trafficking ring operating out of Western Pennsylvania and California.
Authorities said 11 residents of Pennsylvania and nine residents of California were indicted.
According to the indictment, from October 2010 to March 2012, the defendants conspired to distribute 1,000 kilograms or more of marijuana. Distribution of 1,000 kilograms is the highest level offense.
The group operated through the United States Postal Service using Express Mail packages, police said.
According to authorities, at least one of the suspects, Tom Chieu, worked for the post office on California Avenue in the North Side. Investigators said Chieu had $100,000 in cash in a backpack at work.
Authorities said they seized more than $600,000 in cash, five vehicles and two homes, one in Pittsburgh and one in Oakland, Calif., during the investigation.
Neighbors who live near the house on Orchard Spring Road in Green Tree said they saw a lot of police activity and recall often seeing at least one big shipment per day at the house.
“We didn’t know what was going on. We just saw police cars over there,” Marge Pastor said.
The home, owned by one of the suspects, was raided last week.
“When things like this happen around here, of course you think it might be drug-related,” Judy Pastor said.
The United States Postal Inspection Service and the Federal Bureau of Investigation conducted the investigation leading to the indictment in this case.
