Pffft!! B.s. he never showed any signs of being a threat! Earlier news reports had the father stating, from his hospital bed, that his son had threatened to kill the family before. He also said their SUV on fire. And they had to know that you struggle with mental illness. I'm sure there is much more that he has done that the parents are not making public due to guilt over the fact that they did not protect their small children from him. He should have never been sharing a room with a 5 and seven-year-old anyway regardless of his mental health status.
