Amy Hall is charged with murdering two of her teenage children and trying to kill her third child nearly 18 months ago, in their home, outside of Beggs.
"I heard a gunshot. I hurried up and ran to the bathroom right there in our room," said Nikole Toliver.
She was 14-years-old when she survived the shooting. For the first time, Nikole wants to talk about that night and her belief that her mother should not be taking all the blame alone.
"It was all just fast; and I was like mama "'why?"' and she said, "'I have to, they told me to,'" Nikole said.
She has written down every moment of what happened to her family on November 1, 2018.
"When she was doing it, nothing went through my head until after and then I looked at my head and blood all over me," said Nikole. "I turned around and she had the gun in her left hand and she was pointing it straight. It was like all in slow motion, like I just grabbed it and she ran and that was it."
Nikole's older brother, 18-year-old Kayson and her older sister, 16-year-old Kloee, were killed; but, Nikole is not ready to talk publicly about them yet.
Nikole admits her mother had a history of mental illness and even heard voices and would go into fits of anger that could last days, but Nikole says it never got to anything close to this level. Nikole believes someone put the idea into her mother's head or helped her plan it or in some way encouraged her mother's actions.
"She didn't do it by herself, [I] want people to know there were other people involved. She didn't do it by herself," Nikole said.
She's referring to two of her mother's relatives. Although when asked over and over what their motive would be, Nikole doesn't know, but she feels these relatives know more than they are saying. She believes they've lied about different events around the time of the murders, and she wants investigators to look into these issues. She says she's getting a lot of information from her father and isn't ready to see or talk to her mother yet.
"I was confused at first, but I don't think I've ever gotten mad about it, really mad. Upset that people lied about it when there was nothing to lie about," said Nikole. "I don't think they should just blame it all on her, it wasn't just her fault."
Nikole feels her concerns aren't being taken seriously and says she can't move forward with all these questions and suspicions filling her mind.
"I just want answers, that's it, like when I talk to investigators, [I] want them to tell me why. I tell them this happened and this; I want them to actually look into it instead of saying "'okay"' and never getting back to me," Nikole said.
The head of the violent crimes task force in Okmulgee County said Amy Hall's father told police he woke up that morning with Amy next to his bed, getting a gun and then running out of his home. He told police he took off after her, but when he got to her home about a mile away, the shootings were already happening.
Investigators say there is no evidence anyone but Amy Hall fired a gun that morning and no evidence she wrote her daughter a letter explaining her motives or blaming others.
They say there was a teenage boy at the scene who spent the night and a neighbor who showed up after the fact. Investigators say they are limited by what can be said since the case is still pending in court.
