Police are trying to figure out why a belligerent stranger broke into a young mother's house, prompting her to barricade herself in a bathroom with her 2-year-old son while waiting for help to arrive. Keane Winchester, 26, is still shaken by the terrifying incident captured on surveillance camera outside her front door. The suspect screamed while trying to get into the home. He eventually took a piece of wood and used it to smash in the windows. Police say the suspect was “on drugs.”
