David Berkowitz, better known as Son of Sam, is an infamous 1970s New York City serial killer who killed six people and wounded several others. His crimes became legendary because of the bizarre content in the letters that he wrote to the police and the media and his reasons for committing the attacks. With the police feeling the pressure to catch the killer, "Operation Omega" was formed, which was comprised of over 200 detectives; all working on finding the Son of Sam before he killed again.
Berkowitz was eventually caught after receiving a parking ticket at the time and near the place of the Moskowitz murder. That evidence along with letters he wrote to Carr and the Cassaras, his military background, his appearance, and an arson incident, led police to his door. When he was arrested he immediately surrendered to police and identified himself as Sam. After being evaluated, it was determined that he could stand trial. He pled not guilty and received a 365-year sentence.
