(Gresham, OR) -- Three men are under arrest following the "biggest drug bust in Multnomah County Sheriff's Office history." Lieutenant Chad Gaios says officers found 90-pounds of meth, two pounds of heroin and more while serving two search warrants Wednesday night. The drugs have a street value over two-million dollars. Officials said in a press conference Thursday that they believe the drugs were made in Mexico before being brought to Gresham and Portland.
