Dorothy Williams (serial killer)
Dorothy Williams (December 24, 1954 – December 19, 2020) was an American serial killer who killed three elderly people during robberies in Illinois between 1987 and 1990. A drug addict, Williams used the money she stole during the robberies to buy heroin. She also robbed five other elderly people. Initially sentenced to death, her death sentence was commuted to life in prison without parole in 2003 when everyone on death row in Illinois had their sentences commuted by Governor George Ryan over his growing concerns with capital punishment in the state. Williams died in prison on December  19, 2020, at the age of 65, five days before her 66th birthday. Williams strangled 79-year-old Lonnie Laws on December 5, 1987, stabbed 64-year-old Caesar Zurell to death in 1988, and strangled 97-year-old Mary Harris to death on July 25, 1989.
