(Vancouver, WA)  --  Authorities say they've arrested three people as a result of a sizable drug bust in Vancouver.  Detectives say two of the suspects left for Seattle Wednesday, and all three arrived later back in Clark County, where deputies pulled them over and found two pounds of heroin inside their vehicles.  Officials say a raid at the Evergreen Park Apartments yielded more than 14 pounds of meth and six pounds of heroin, and more than 200-thousand dollars in cash and a stolen AR-15 rifle were seized from a safe in Portland.  Each of the three suspects is charged with possession, delivery, and other charges.
