The Texas Department of Public Safety released a dashboard video taken of the arrest of Sandra Bland from a police officer’s cruiser.
The Chicago-area woman was pulled over in Prairie View, Texas, during a routine traffic stop on July 10. After being held in the local jail for three days, she was found dead in her cell.
Officials say Bland hanged herself with a plastic garbage bag, but family members are disputing that.
The Bland case is the latest in a string of high-profile incidents around the country that have highlighted the strained relationship between the African-American community and local police.
