(Newser) – She was, as the San Francisco Chronicle declares in its headline, "the most dangerous woman in San Francisco." The story by Katie Dowd tracks the story of lifelong con artist Iva Kroeger, born Lucy Cooper, whose first arrest came in Chicago in 1945 after she went around pretending to be a war-hero nurse. (The offense was illegally wearing the uniform.) The most sensational part of her life of crime, however, may be familiar to true-crime buffs. In the 1960s, she conned and murdered an older couple who ran a cheap motel in Santa Rosa, California, then buried their bodies under the garage floor of her home in San Francisco. She took over their motel before police unraveled what happened and closed in. Kroeger was on the lam for a while, her photo plastered on newspapers as a wanted killer. (In this wild stretch, she managed to con her own son and kidnap two grandsons.)
