Brown was born in 1962 in Waukegan, Illinois, the fifth of eleven children, and was assessed as having an IQ in the range of intellectual disability and as being dependent and highly suggestible. In 1983 she left her fiance to live with Alton Coleman.
Between May and July 1984 the two of them travelled through Illinois, Wisconsin, Michigan, Indiana, Ohio and Kentucky, and eight people were killed: Vernita Wheat, nine; Tamika Turks, seven; Donna Williams, twenty-five; Virginia Temple and her daughter Rachelle, nine; Tonnie Storey, fifteen; Marlene Walters; and Eugene Scott. They were strangled, beaten or stabbed. There were also rapes, abductions and armed robberies. The pattern was that Coleman gained the confidence of Black families by presenting himself as a friend of a relative, and they were then attacked in their own homes. The FBI put Coleman on its ten most wanted list, the manhunt was national, and the two were arrested in Evanston, Illinois, on July 20, 1984.
Brown was tried separately in several jurisdictions. She was sentenced to death in Indiana on June 23, 1986 for the murder of Tamika Turks, and to death in Ohio for Marlene Walters. In 1991 the governor of Ohio, Richard Celeste, commuted her death sentence to life, citing her intellectual disability and her subordinate role, and the Indiana sentence was also reduced. She is serving life in Ohio.
Coleman was executed in Ohio on April 26, 2002. The division of responsibility between the two has been argued over ever since: the prosecutions treated Brown as a full participant, while the clemency decision accepted that she was led. Both accounts are in the record and this entry does not resolve them.
