MINNEAPOLIS—A woman’s “illegal buying spree” armed a man with the high-powered firearms that he used to kill three Minnesota first responders during a standoff at a home where seven children were inside, federal authorities said Thursday.
The guns bought by Ashley Anne Dyrdahl included three AR-style semiautomatic rifles, including one with a device that doubles the rate of gunfire, and two semiautomatic pistols, court documents said. In addition, investigators found “a stockpile of fully loaded magazines as well as boxes with hundreds of additional rounds of ammunition” in the bedroom Dyrdahl and gunman Shannon Gooden shared, the indictment said.
