Thank God no child was hurt or killed.

I am happy for your wonderful outcome today. That is a scary situation.
When my oldest granddaughter was in the 8th grade, they had a similar scare. One of the boys in her class had a list with people's names on it, and hers was one of them. He had been talking about killing kids on the last day of school and some child overheard. When the authorities found out about it, he was removed from school and they found his list. But not knowing if there may have been a second one involved with the plot, people were so scared they were taking their kids out early. My daughter-in-law called me to go pick up my granddaughter, she wanted her out of there too. I was only to happy to oblige her, and enjoyed coddling my granddaughter the rest of the day.
School shootings and killings are just too terrifying. And life is too precious to waste so wantonly.
