Investigators say that when they captured Marine veteran Bryan Riley outside the Lakeland, Florida, home where he allegedly killed a couple, their 3-month-old son, and the boy’s grandmother, he told them, “You know why I did this.”
But they say they don’t and, in fact, may never know why Riley launched an attack against a family he had no known connection with, except that he may have been mentally ill. Riley’s girlfriend told investigators that he had been saying he could communicate directly with God.
