Daniel Perry, a former US Army sergeant who was convicted of murdering a protester at a Black Lives Matter rally in 2020, was released from prison Thursday after he was pardoned by Texas Gov. Greg Abbott.

Abbott’s decision comes after the Texas Board of Pardons and Paroles voted unanimously Thursday to recommend a full pardon and the restoration of firearm rights for Perry, who was sentenced last year to 25 years in prison. Shortly after he was pardoned, Perry was released from Texas Department of Criminal Justice custody, a spokesperson for the agency told CNN.

Abbott asked the board to conduct an investigation in April 2023, and in a statement on Thursday, the board said its “investigative efforts encompassed a meticulous review of pertinent documents, from police reports to court records, witness statements, and interviews with individuals linked to the case.”
