The first eight-episode installment of the NBC anthology series will be Law & Order: True Crime - The Menendez Brothers Murders. It will center on Lyle and Erik Menendez, who were convicted of murdering their parents and sentenced to life imprisonment without the possibility of parole in 1996. The brothers, who were 21 and 18 years old, respectively, at the time of the 1989 murders, were tried separately but eventually convicted in a third trial after no verdicts were rendered in the first two trials because of hung juries.
