FILE – In this Aug. 28, 2020 file photo, family members of Ronald Greene listen to speakers as demonstrators gather for the March on Washington, in Washington, on the 57th anniversary of the Rev. Martin Luther King Jr.’s “I Have A Dream” speech. Officials told The Associated Press, federal authorities are investigating the death of Greene during what Louisiana State Police described as a struggle to take him into custody following a rural police chase last year. The death of the 49-year-old remains shrouded in secrecy because State Police have declined to release body-camera footage related to the May 2019 chase north of Monroe, La. (Michael M.
