I'm friends with an eyeball witness to what happened. PK Sam, a former New England Patriots wide receiver who graduated from my hometown high school years later than me. He said the shooting was over playtime. It was utter chaos. He grabbed one of his sons, but could not find the other one or his wife until sometime later.
