Erik Menendez responds to Brother Lyle's apology for harassment

“She told me to stop and that I was exaggerating,” Lyle said during the trial. “And that my father has to punish me if I do something wrong. And she…she told me he loved me.”

Nevertheless, Erik in particular wanted to make it clear how much he loved his mother how guilty he still feels over her loss.

“I miss my mother very much,” he said in the documentary. “I wish I could go back and talk to her and hug her and tell her that I love her and that I wanted her to love me and be happy with me and be happy that I'm her son and that joy and feels this connection.” . And I just want that.”

The brothers also discussed the difficulty of revealing so much of their lives during the trial, with Lyle saying he “deeply didn't want to talk about anything that happened in our past.”

But as defense experts Dr. Ann Burgess noted in the documentation, after meeting the boys—Lyle and Erik were 21 and 18 years old, respectively—shortly after the murders: “I said that something had to happen in the family for this to happen.”

“They don’t need money or any other motive or revenge or any other motive we can think of,” she continued. “I said, 'There's something wrong in the family.'”
