Lester "Baby Face Nelson" Gillis, whom newspapers of the era dubbed "Dillinger's aid", had managed to elude the federal dragnet.
By late November 1934, the new Public Enemy Number One was looking to hide out in the isolated piney woods of Lake Geneva, Wisconsin.
With his vehicle losing power, Nelson was next pursued by a Hudson automobile driven by two more agents, Herman Hollis and Samuel P.
[6] With his new pursuers attempting to pull alongside, Nelson swung the Ford into the entrance of Barrington's Northside Park, just across the line from Fox River Grove, and skidded to a stop.
With their car stopped at an angle, Hollis and Cowley exited, took defensive positions behind the vehicle and, as Helen Gillis took cover in a field, opened fire on Nelson and Chase.
Nelson had been shot a total of nine times; a single (and ultimately fatal) machine gun slug had struck his abdomen and eight of Hollis's shotgun pellets had hit his legs.
[8] After telling his wife "I'm done for", Nelson gave directions as Chase drove them to a safe house on Walnut Street in Wilmette.
Following an anonymous telephone tip, Nelson's body was discovered wrapped in a Native American patterned blanket[10] in front of St. Paul's Lutheran Cemetery in Skokie, which still exists today.
[11][12] After surrendering on Thanksgiving Day, Gillis, who had been paroled after capture at Little Bohemia Lodge, served a year in prison for harboring her late husband and died in 1987.
