Kim adopted Rylan when he was just a baby - but he has gone on to display some extremely disturbing behaviour.
Sitting down on The Dr Phil Show, she explained that Rylan has an imaginary robot friend called Bleeder, who once encouraged the little boy to lock himself in a bathroom and chop his on fingertips off.
She continued: "He has an obsession with knives. Rylan talks about knives, he thinks about knives, if he sees any sharp object then he has to have it.
"He talks about stabbing us with them, about how he's going to lift them up over his head and plunge them into our chests, so that he gets the best impact.
She added: "I take his threats very, very seriously. He has shown every bit of intent."
"My biggest fear is that we’re raising a school shooter, a mass murderer, a serial killer.
"In Rylan’s lifetime, we’ve placed Rylan in six hospitals,” Kim said, noting that a therapist compared the kid to serial killer Ted Bundy.
“I want to live with Rylan, but to have him at home is too terrifying,” she added during the Dr. Phil segment.
It is not Rylan's fault, however; Dr Phil - who is a mental health professional as well as a daytime talk show host - reminded viewers that the boy’s mother was a meth addict and that both of his biological parents had been diagnosed as bipolar.
“The truth is there’s a lot we don’t know about the prenatal effects of exposure to meth,” Dr. Phil said. “But we know that it’s not good.”
