In 1990, Pat Brown rented a room to someone who turned out to be a suspect in the murder of a female jogger. She warned law enforcement of her suspicions. When her local police proved ineffective at investigating the crime, her frustration led her to become a criminal profiler. In 1996, she founded the Sexual Homicide Exchange. Her time is dedicated to helping the families of homicide victims, and assisting law enforcement with unsolved cases around the country. She is also working to improve the present system of serial homicide investigation. In addition, Pat Brown serves up tough love for people who glamorize murders in her first book, "Killing for Sport: Inside the Minds of Serial Killers."
