The FBI is investigating the death of a Black man in Alabama, who was found hanging in an abandoned house, following a request from a local sheriff amid fears among community members who accuse local law enforcement of longstanding, unchecked misconduct.

Sheriff’s deputies found Dennoriss Richardson, 39, in September in a rural part of Colbert County, miles away from his home in Sheffield, a city of approximately 10,000 people near the Tennessee River.

The Colbert County Sheriff’s Office ruled Richardson’s death a suicide. But Richardson’s wife, Leigh Richardson, has said that is not true, explaining her husband did not leave a note and had no connection to the house where he was found.

Instead, the 40-year-old fears her husband’s death was related to a lawsuit he filed against the local police department in February. Dennoriss Richardson, who coached kids in baseball and football, had alleged he was assaulted, denied medical attention, sprayed with tear gas and shocked with a Taser while in jail.
