The infamous case of the Menendez brothers is a never-ending, complicated story with new evidence showing up almost every year.

In summary, 18 year-old Erik and 21 year-old Lyle Menendez shot and killed their parents Jose and Kitty Menendez in their California home during the summer of 1989. This was due to the trauma their parents, mostly Jose, caused during their childhood. The brothers were sexually abused by Jose, with Lyle’s starting at the young age of 8. Erik and Lyle endured the abuse, scared to tell anyone what was happening.

The brothers were charged with first degree murder, the jury siding against them, even though both Erik and Lyle testified to being heavily abused. They were sentenced to life in prison without the possibility of parole. They were sent to separate prisons until reuniting in 2018, being put in the same prison.

Now, they are known by news stations, such as NBC News, as “model inmates.” In just a few weeks on December 11, a retrial will take place to determine if the brothers should be eligible for parole.

Below is a detailed timeline of the events leading up to Ryan Murphy’s “Monsters,” his recent interpretation of the Menendez brothers.
