Lyle (L) and Erik (R) Menendez
On the evening of August 20, 1989, Erik and Lyle Menendez opened fire in their parents Beverly Hills mansion and murdered them. For seven months, authorities investigated the case with no arrests-- at first, they suspected the mafia was responsible for the deaths. After seven months, Erik and Lyle Menendez were arrested, and seven years later, they were sentenced to life in prison without the possibility of parole. At the time of the murders, Lyle and Erik were 21 and 18 years old, respectively. They had purchased two 12-gauge Mossberg shotguns
two days before the murders, and used fake identification to the purchase the guns, according to CNN.
After their parents deaths, Erik and Lyle spent lavishly-- a 1995 CNN article provided proof that the brothers spent about $15,000 on Rolex watches just four days after the murder. Lyle purchased a Porsche sports car and a restaurant in Princeton, as well. According to writer and investigative journalist Dominick John Dunne, the brothers spent a total of $700,000 in the months following Kitty and Jose's deaths.
