Murder in the Fast Lane (15x33)

:

Mickey Thompson was an American racing legend, once one of the fastest men on earth. During his career, he set 395 different speed records. But his career came to an end in 1988, when he and his wife, Trudy, were shot and killed outside their home in California's San Gabriel Mountains. Their murders remained an unsolved mystery for more than a decade. But Thompson's sister, Colleen Campbell, never stopped hunting for the killers. She says she knows who did it - her brother's business partner, Michael Goodwin. But can she help police prove it? Correspondent Bill Lagatutta reports on a case he's been covering for years.
