The first of two trials, broadcast on Court TV, gripped the nation, as did O.J.'s trial. Simpson in 1994, and it is believed to have played a role in today's fascination with 'true crime'. Prosecutors argued that the pair were in fact out to inherit their father's multimillion-dollar fortune, and the Menendez brothers were sentenced in 1996 to life in prison without the possibility of parole.
