Between February 1975 and January 1976 a series of gruesome unsolved murders occurred in Broward and Miami-Dade Counties, Florida. Officials believe that the offender deflated the tires of his victims (at least 12 women but believed to be as many as 30) before offering his services as a regular guy who could help out before sexually assaulting and brutally killing the women. Some officials believe that the Flat-Tire murders extended to Idaho, Utah, Colorado, and California, but this claim has never been proven. To this day no one has been able to substantiate the identity of this vicious killer.

Known to most Americans as the beloved lead of Hogan's Heroes, in his private life he was a libertine with an insatiable appetite for women as well as filming his escapades with friend and cohort John Henry Carpenter. By the late '70s Crane was performing in regional theater productions while attempting to work his way back to television when was murdered at the Winfield Place Apartments in Scottsdale, Arizona, on June 29, 1978.

Crane was found bludgeoned to death in his apartment with what local officials believe was a camera tripod, but with no physical evidence they were hamstrung. It's believe that Crane contacted Carpenter prior to his death to break off their friendship which had turned toxic, something that many theorists point to as a motive for Carpenter. However, no charges were filed against Carpenter even after police found smears of blood that match Crane's blood type on Carpenter's car. Carpenter was officially charged with Crane's murder in 1994, but after he was acquitted on all charges the case went cold.
