An Elma man accused of running a cross-border drug ring pleaded guilty today to marijuana trafficking.

Assistant U.S. Attorney Michael L. McCabe said Nicholas Korzkowski, 30, helped obtain marijuana from Canada and then distributed it to customers in the Buffalo area. He said Korzkowski also housed marijuana at a building on Harlem Road in West Seneca.

Korzkowski's guilty plea is the result of an investigation by the FBI, the U.S. Drug Enforcement Administration, Immigration and Customs Enforcement, the Erie County Sheriff's Office and the Buffalo, Hamburg, West Seneca and Lackawanna police departments.
