William D. Williams, a 34-year-old African American man from Cleveland, Ohio, died from a gunshot wound to the head and was found at his home on Grantwood Avenue on February 24, 2015. Cleveland police classified the death as a homicide and opened an investigation.

Police identified Williams’ girlfriend, Dana Johnson, then 36, as the person responsible for the shooting. After the incident she left the scene and was located by Pennsylvania State Troopers on Interstate 376 in Brighton Township. Troopers say Johnson shot herself when they approached; she was taken to a hospital in critical condition and later pronounced dead. Cleveland police had obtained a homicide warrant and charged Johnson with aggravated murder before her death.

Williams was the brother of Cleveland Police Chief Calvin Williams, and the case received extensive media attention because of the family connection and prior allegations of domestic violence mentioned in the investigation. Does anyone have information about the leadup to that night or the prior incidents of domestic violence?
