John Brookman Perry, 48, was shot and killed on March 8, 2011, while serving on a U.S. Marshals Service team that went before dawn to execute a felony arrest warrant at a residence on Osage Street in St. Louis, Missouri. The warrant related to allegations including assault on a law enforcement officer and drug possession. Officers first removed children from the home; while searching for the wanted man, gunfire erupted from inside and Perry was struck.

At least two other officers were wounded in the initial exchange. Authorities identified the shooter as Carlos Boles, who was ultimately shot and killed during the standoff. Perry was taken to Saint Louis University Hospital and died later that day, with reports placing his death at about 7 p.m. He had served nearly a decade with the U.S. Marshals Service and was later honored with a posthumous promotion.

Anyone who knew Perry, Boles, or the Osage Street neighborhood and has information about the events that night is asked to come forward.
