A federal grand jury returned an indictment this week charging three men, two of them from Mexico, with selling cocaine and heroin.
The indictment charges Jose Manuel Lua-Guizar, 25 and Max Riestra, 40, both of Mexico, and Pethrod Dunnigan, 37, of Buffalo, with conspiracy to distribute cocaine and heroin.
Guizar and Riestra also face money laundering charges.
Assistant U.S. Attorney Michael J. Adler said the case began with an investigation into a sophisticated drug-trafficking organization with ties to a Mexican drug cartel operating out of Los Angeles.
The indictment claims the organization shipped drugs to New York and other states and then used bank accounts, primarily through Bank of America, to launder drug money back to Los Angeles.
The charges are the result of an investigation by the Drug Enforcement Administration, Immigration and Customs Enforcement, Homeland Security Investigations and the Internal Revenue Service, Criminal Investigations Division.
