Linda Taylor (one of at least 33 aliases) became famous in 1976 when Chicago newspapers, and later Ronald Reagan, dubbed her the “Welfare Queen.” She lived off of public funds, while driving a Cadillac and wearing fur coats.
Defrauding welfare, however, was only one of her scams. Taylor tried to collect inheritances. She probably sold babies on the black market. And she is probably responsible for at least two deaths.
In part 11 (of 12) of this article, author Josh Levin implies that Taylor was a psychopath.
