The murder was planned for 7 months. The victim Bobby Franks was a distant cousin of Loeb's. On May 21, 1924 in the afternoon, Bobby Franks was walking home from school when an automobile pulled up near him. Loeb asked Franks to come over to the car, asked him to get in the car to discuss a tennis racket, then killed him with a chisel as the two drove off. Leopold and Loeb drove their rented car near the Indiana line, where they stripped Franks, poured acid over his body to make his body hard to identify, then put the body in a concrete culvert. They burned Franks' clothing. That evening Mrs. Franks received a phone call from Leopold. Leopold told Franks that Bobby had been kidnapped, was safe, and that she should expect a ransom note soon. The next morning the Franks family received a special delivery letter asking that they immediately secure $10,000 in old, bills and telling them to wait further instructions that afternoon. Leopold called Bobby's father, to tell him a taxi cab was about to arrive at his home and that he should take it to a drugstore in Chicago. Mr. Fanks never got into the cab that pulled up to his home. Instead he got a call from the police telling him that they found his son, dead.
