On November 27, 1934, a running gun battle between FBI agents and Public Enemy # 1 Baby Face Nelson took place in Barrington, resulting in the deaths of Special Agent Herman "Ed" Hollis and Inspector Samuel P. Cowley. Nelson, though shot nine times, escaped the gunfight in Hollis's car with his wife, Helen Gillis. Nelson succumbed from his wounds at approximately 8 p.m. that evening and was unceremoniously dumped near a cemetery in Niles Center (now Skokie), Illinois. Infamous for allegedly killing more federal agents than any other individual, Nelson was later buried at Saint Joseph Cemetery in River Grove, Illinois. A plaque near the entrance to Langendorf Park, part of the Barrington Park District, commemorates the agents killed in the gunfight.
