I think that the schizophrenia is usually already there but at a level where it isn’t interfering with daily life. Once the drug use begins the lid gets blown off and it looks like the drugs caused the disease. But who knows, really.
The shooting was certainly planned and depraved, but it also looks like she didn’t have any sort of reason for doing it. The senselessness of it makes me suspect that it’s craziness acting itself out.
It appears she is in a divorce deal and she and her boyfriend were motivated by hate and spite for her husband, to kill the dog in an effort to, “Get back at him” or “Pay him back”. It was apparently the husbands dog.
It’s why they were drinking and were photographed with bottle of alcohol and were smiling and laughing. Sick sick.
The motive appears to have been to punish or hurt the ex-husband which while evil, isn’t a senseless act.
She may very well be mentally ill, but it seems more bipolar than schizophrenic. And plenty of non mentally ill people commit cruel and depraved acts under the influence of drugs and alcohol while their judgement, reason and self control are on vacation and letting their inner bitch out to play.
Posting the video on social media is a bi-polarish thing to do also. When they are in their manic phase they tend to think the normal social rules only apply to others and not themselves.
I can very well guess that her defense lawyer will certainly try to play the mental health crisis card unless he is an underpaid public defender who gets paid the same regardless of whether they actually do their job or not.
