According to People , the show will focus on Hernandez, who was acquitted of double murder charges in the deaths of two men outside a Boston nightclub in 2012. Despite his initial acquittal, the Supreme Judicial Court of Massachusetts reinstated the murder conviction of Hernandez in March 2019, per CNN .

Though he was originally found not guilty, Hernandez was already serving a life sentence for masterminding the murder of his fiances sisters boyfriend, Odin Lloyd, in 2013. The then 27-year-old was not eligible for parole, and five days after he was acquitted in 2017, he died by suicide when he hanged himself with a bed sheet in prison.

The former football player reportedly tried to repair the damage between him and his mom after their relationship supposedly fractured following the 2006 death of Hernandezs father.

Theres so many things I would love to talk to you about, so you can know me as a person, he told his mom in one phone call, which were recorded by authorities and released as public record. But I could never tell you. And youre gonna die without even knowing your son.

Take a peek at the Killer Inside official trailer:

Viewers will go on to learn more about their relationship through recorded calls, which explain how Aaron ultimately blamed his mom for many of his problems.

I was the happiest little kid in the world, and you f*cked me up, he said to her.

I aint living with that, she replied.

You did, he responded. I had nobody. Whatd you think I was going to do? Become a perfect angel?

You ruined me, he told her. Youre the reason I could never pay attention in school and sh*t. You were supposed to get me my medication.

I knocked you over the head with a frickin hammer, she responded. That was your medication.

Hernandezs older brother also told People in a 2018 interview that Aaron suffered physical, emotional, and sexual abuse before devolving into a life of violence, which the documentary series will also address.
