It’s one of the oldest and most infamous cold cases in Cook County.

The evening of Dec. 28, 1956, two sisters left their home in Chicago’s Brighton Park neighborhood.

Barbara and Patricia Grimes were big fans of Elvis Presley and had begged their mother to let them see the singer’s first movie, “Love Me Tender,” at the nearby Brighton Theater. It’s believed they watched two showings of the film, then left for home.

But they never made it.

Larry Potash has the story of a crime that changed Chicago forever.
