(Vancouver, WA) -- Police say an investigation into a drug overdose death in Clark County has resulted in a drug bust. Last May, the Clark County Sheriff's Office investigated a death that happened because the victim took counterfeit Oxycodone that was laced with fentanyl. Over the last five months, an investigation led detectives to a house near Northeast Padden Parkway and Ward Road. A search of the house found 11-thousand counterfeit Oxycodone pills suspected of containing fentanyl, a large quantity of steroids and other pills, six guns, and 32-thousand dollars in cash. Two people were arrested.
