The family of virgin killer Elliot Rodger is speaking out.
Speaking on behalf of the grieving parents, family friend Simon Astaire says they are in indescribable pain—not for their son's life, but the six innocent young men and women he killed.
"I thought he was one of the loneliest people I have ever seen in my life," Astaire said, "Quite seriously, they are unable to string a sentence together."
He called Elliot Rodger "a monster" and read a statement that came directly from the parents: "We are crying in pain for the victims and their families. It breaks our hearts to a level we did not think possible. The feeling of knowing that it was our son's actions that caused the tragedy can only be described as Hell on Earth. He is in many ways, a monster."
And we're learning more about the killer's twisted world and his desire to murder his six-year-old half-brother because he was jealous of the little boy.
A video shot by Elliot shows his looming shadow as he approaches his six-year-old half-brother, Jazz.
Elliot asks, "How are you doing, Jazz?
"Okay," replied Jazz.
Elliot shot the video in hills near his father's Los Angeles home, overlooking million dollar mansions.
In his 137 page manifesto "My Twisted Life," he writes about his hatred for Jazz, stating, "Girls will love him. He will become one of my enemies. I decided I would have to kill him."
In the video he even appears to encourage little Jazz to jump off the hilltop when Jazz playfully says, "I also wish I could just, like jump off this hill and go flying."
Elliot tells Jazz, "That would be fun."
INSIDE EDITION has learned that Elliot kept a secret YouTube channel under the phony name Valtharion. He peppered the site with hostile comments. He posted a video of Hitler with the comment: "Killing all the celebrities would be a good thing."
YouTube user Travis Johnson noticed Elliot's disturbing comments online and reached out to him, offering advice, but Elliot ignored him.
Johnson told INSIDE EDITION, "He was a very troubled individual. I know I shouldn't, but I feel extremely guilty. I feel like I should have done more."
Meanwhile, hundreds of students at U.C. Santa Barbara staged an unusual memorial, paddling into the ocean on surfboards to form a circle and pray for the dead.
