When the operator asked her what happened, she said: "First, I tried to give them bathroom cleaner. I put in their mouth, but they don't drink it. I want them to drink it. They don't drink it ... I grabbed their neck ... and they are no more."

"They are autistic. I don't want my kids to be autistic."
