and this
A visit by a mental health clinician at Henderson Behavioral Health ended with a determination Cruz was not at risk to harm himself or others, and the teen was instructed to sign a safety contract.

(The qualifications of the "clinician" are not mentioned.)

He told police that voices in his head -- called demons by law enforcement sources -- told him to carry out the attack.

And we're all way to sophisticated today to believe self-mutilation (he was a cutter) and homicidal violence could have anything to do with demonic possession. His Public Defender says he is "just a child with poor impulse control."
