36 - 7: Murder by Clown

Marlene Warren answered the door of her Florida home on May 26, 1990, to find a clown handing her balloons and flowers. In an instant, she was shot dead while her 21-year-old son looked on. Warren's son, Joe Aherns, opens up.

The clown then calmly walked back to their car and drove away.
