Golden State Killer
In April 2018, the public was shocked when the news broke that police finally arrested a suspect in the Golden State Killer case. The Golden State Killer terrorized California in the '70s and '80s with a string of 12 murders and 42 rapes. After nearly 42 years, authorities apprehended 72 year old Joseph James DeAngelo when they found compelling DNA evidence linking him to the crimes. Prior to his arrest, DeAngelo spent 30 years working for the Exeter, California police department and apparently lived a quiet suburban life.
Daniel Holtzclaw, Serial Rapist
This is one very, very bad cop. Former Oklahoma City police officer Daniel Holtzclaw was found guilty of 18 charges, including "sexual battery, forcible oral sodomy and rape," reported CNN'S Michael Martinez. Holtzclaw committed these crimes while on-duty, targeting one of Oklahoma's poorest neighborhoods, and assaulting exclusively black women. While his defense resorted to victim-blaming, the evidence against Holtzclaw was overwhelming, and the jury sentenced him to 263 years in prison.
Mikhail Popkov, AKA the Werewolf
The monstrous nickname "the Werewolf" suits Mikhail Popkov, a former Russian police officer who used his uniform and cruiser to prey upon intoxicated women. Providing them with a false sense of trust and safety, Popkov would lure these women into his car, drive them out to the woods, and then viciously attack them with "a slipknot, knife, awl, screwdriver or an axe which he used up to 17 times on some victims," wrote Siberian Times.Following his attack, the Werewolf would sexually assault his victims, then kill them — though in some cases it is believed that he murdered his victims first, then engaged in necrophilia. Popkov eventually confessed to 24 of the murders, claiming that the only reason he ceased his activity was because he was impotent from syphilis and could no longer enjoy murder on a sexual level. Police suspect Popkov is responsible for at least five other killings, though the number could be far higher than that.
Gennady Mikhasevich, Volunteer Killer
Gennady Mikhasevich served in the Voluntary People's Druzhina, a volunteer police force in the Soviet Union. He assisted in the investigation of several rapes and killings that took place between 1971 and 1985. Unbeknownst to his fellow volunteers and members of the regular police force, the crimes were not random and unconnected as many believed, but were in fact perpetuated by one man: Mikhasevich. When Nikolay Ignatovich, a young investigator, began sharing his serial killer theory, Mikhasevich sent an anonymous letter to police in hopes of derailing their investigation. However, as the letter was handwritten, investigators compared it to writing samples of people in the area, and matched the letter to Mikhasevich's hand. He was executed in 1987.
