48 Hours

Murder in the Fast Lane (20x27)

:

Racing legend Mickey Thompson made headlines in 1960, when he set the land speed record of 406 miles per hour in the salt flats of the Utah desert. In 1988, he made headlines again for how he died: Mickey and his wife Trudy were murdered execution-style outside their California home. There was no gun, no DNA, no hard evidence at all. But there was Mickey Thompson's younger sister Collene, who vowed to find justice. After 20 years, has a killer finally met his match? Correspondent Bill Lagattuta reports.
