Prosecutors decided not to press charges in the death of a George Washington University graduate student, the Washington Post first reported.
Patrick Casey died in September after a late-night altercation at a McDonald's restaurant on M Street in northwest Washington. Casey’s death has been classified as a justifiable homicide by a citizen, according to the Post. The 33-year-old was an Army veteran who had returned from Afghanistan.
Previously, Casey's parents told News4 their son was sucker-punched while breaking up a fight.
But a few days later, D.C. police said Casey was involved in the fight and may have even started it. Police said they interviewed all the suspects in the case.
Casey or someone else in the group he was with hit or punched another individual, and then Casey was punched. Police said he fell to the ground and hit his head, leaving him brain dead.
In a statement, William Miller of the U.S. Attorney's Office said that after an investigation, prosecutors "determined there is insufficient evidence to pursue criminal charges in Mr. Casey's death." The U.S. Attorneys office notified Casey's family of their decision last month.
