Murder of the Grimes sisters
The murder of the Grimes sisters is an unsolved double murder which took place in Chicago, Illinois, United States, on December 28, 1956, when two sisters named Barbara and Patricia Grimes—aged 15 and 12 respectively—disappeared while traveling from a Brighton Park movie theater to their home in McKinley Park. Their disappearance initiated one of the largest missing persons investigations in the history of Chicago. The girls' nude bodies were discovered alongside a deserted road in Willow Springs on January 22, 1957.
Although the sisters' autopsy reports concluded they had been murdered within five hours of their last confirmed sighting, and that both girls had died of secondary shock, numerous individuals attested to having seen the girls alive in the weeks between the night of December 28 and the subsequent discovery of their bodies.The murder of the Grimes sisters has been described by authors as a crime which "shattered the innocence" of Chicago. This case is also acknowledged as one of the most labor-intensive missing person and murder investigations in Cook County, and remains one of Chicago's most infamous cold cases.
