Two hours past midnight on April 7, 2001, a nineteen-year-old black man, Timothy Dewayne Thomas, was shot and killed by a police officer in Cincinnati's inner-city neighborhood called Over-the-Rhine. The police officer, Thomas Roach, claimed that Thomas had fled from police on foot when they had approached him. In hot pursuit, Roach headed off Thomas at the end of an alley. Roach fired his weapon because, according to one version of events he later gave investigators, it appeared that Thomas was reaching into the waistband of his oversized pants. Thomas, shot once, was unarmed.
Thomas had been the fifteenth African-American male who had been killed by the Cincinnati police, and the fourth in the previous six months. As word spread the next day about Thomas's killing, many residents in Over-the-Rhine as well as black neighborhoods throughout the city were overwhelmed with grief and outrage. Spontaneously, people went into the streets, venting their hostility against the symbols of white power and property.
