FILE - In this Nov. 18, 2012 file photo, New York Jets running back Joe McKnight (25) during the fourth quarter of an NFL football game against the St. Louis Rams in St. Louis. The new trial for Ronald Gasser, convicted of manslaughter in 2018 by a jury vote of 10-2 in the 2016 shooting death of McKnight following a traffic dispute, cannot include a murder charge, a Louisiana judge ruled Wednesday, Feb. 10, 2021. The U.S. Supreme Court held that Louisiana law allowing convictions on 10-2 or 11-1 votes is unconstitutional, which resulted in Gasser being granted a new trial. (AP Photo/Tom Gannam, File)
