Mrs. Brown, a 65-year-old woman, was terrified of being alone at night and suffered from nyctophobia. Her husband had been dead for several years, and her 40-year-old son lived in another state with his family. She often called him in the middle of the night in a state of panic, and he felt helpless about her situation. She lived in a senior housing community that never had any problems with crime.
