Small Mistakes That Brought Down Big Criminals

Serial killers are often depicted as calculating and elusive. After all, that's how they avoid getting caught long enough to commit multiple murders. However, it's not always a big mistake or complex investigations that lead to their downfall — sometimes the smallest errors can end a reign of terror. Here's a look at how tiny mistakes led to the capture of some of the America's most notorious killers.

Dennis Nilsen – A Blocked Drain

Dennis Nilsen, known as the Muswell Hill Murderer, killed at least 12 young men and boys between 1978 and 1983. Nilsen's downfall came not from a direct link to the murders but from a plumbing issue. After dismembering his victims, he flushed their remains down his toilet, which led to a blocked drain. When plumbers discovered human bones and flesh in the pipes, they notified police, unraveling Nilsen's gruesome acts, leading to his arrest and life imprisonment.

David Berkowitz – A Parking Ticket

David Berkowitz, better known as the Son of Sam, terrorized New York City in the late 1970s with a series of shootings. His capture was the result of a keen observation by a citizen rather than a calculated police operation. A witness noticed Berkowitz near a car parked illegally by a fire hydrant. When the police checked the parking tickets issued in that area, they found Berkowitz's car had been ticketed. This led them to his residence, where they arrested him, finding the notorious .44 caliber revolver in his possession.

Dennis Rader – A Floppy Disk

Dennis Rader, the infamous BTK Killer (Bind, Torture, Kill), evaded capture from 1974 to 1991. Craving recognition, Rader began communicating with the media decades after his last murder, ultimately leading to his capture. In a particularly bold move, Rader sent a floppy disk to a TV station. Forensic investigators found metadata on the disk that included a deleted file with the name "Dennis" and the church where he was a council president. This small digital footprint led authorities directly to Rader, who is currently serving 10 consecutive life sentences.

Ted Bundy – A Series of Traffic Stops

Ted Bundy, one of the most notorious serial killers in history, confessed to more than 30 murders, though he is suspected of committing up to 100. His capture wasn't the result of an elaborate sting or a high-profile investigation, but rather mundane traffic stops. In 1975, Bundy was first arrested after a police officer noticed him driving his VW Beetle without lights at night. Upon researching his vehicle, authorities found incriminating items like a ski mask, an ice pick, and handcuffs.

Bundy then escaped from prison but was captured again four days later after making an illegal U-turn in a stolen vehicle. His final arrest followed another minor traffic violation when a routine check revealed his car was stolen.

Whether it's a minor traffic violation, a plumbing complaint, a carelessly sent floppy disk, or a simple parking ticket, these small slips provided the breakthroughs needed to solve some of the most challenging criminal cases and ensure the capture and punishment of even the most careful of criminals.
