Andrea Yates

Source: ABC News
Infamous for the murder of her five children, Andrea Yates currently resides in a minimum security psychiatric hospital after being found not guilty by reason of insanity in 2006. After years of depression and multiple suicide attempts, she was eventually left alone with just enough time to draw a bath and drown each of her children one by one.
After drowning them, she placed her youngest sons in their beds while leaving her oldest one in the tub with her only daughter in his arms. Before being arrested for the murders, she called her husband at work and simply repeated the phrase “It’s time” over and over again.
Griselda Blanco
Known as The Cocaine Godmother, Griselda Blanco was one of the most brutal and notorious drug lords in the history of the cocaine trade. After a violent upbringing that was strung together by a series of criminal acts, Griselda eventually found her way into the cocaine business where she played a key role in what would become known as the Cocaine Cowboy Wars of the 1970s and 1980s in Miami.
Blanco was well known for ordering brutal assassinations when warring with other drug lords and for running her business even while serving prison terms throughout her life. After being deported to Colombia, she spent the remainder of her days plying her trade until she was shot twice in the head by a gunman riding a motorcycle on September 3, 2012.
