Laurin Putnam died in April 2012 at her home. The Salem Statesman Journal reports ( ) that in the days afterward, several people were arrested.

The U.S. Justice Department said Thursday that Sergio Quezada-Lopez was a high-level operative in the heroin distribution. It said he was in charge of a network of houses where drugs were stored in Portland and Vancouver, Washington, taking orders for heroin and directing its delivery.
