(WCMH) — Denver Ham gripped his daughter Riley's shoulders tight in a protective hug outside Legend Elementary School in Newark.
"I couldn't lose another child," Ham said, choking back tears.
Riley, 7, told her family she had a "bad day" at school on Wednesday. The second-grader said a substitute teacher who called himself "Mr. S." threatened her class.

"He doesn't deal with bad behavior and said if we act up or do anything that he didn't tell us, that he would cut our heads off and bury us," Riley said.
