America's Most Famous Murder Cases.

1.John Wayne Gacy: The Killer Clown John Wayne Gacy was a notorious serial killer in America who performed as "Pogo the Clown" at children's events. Gacy began torturing, raping, and killing 33 young men in 1972; the most of them were still teenagers. He ruled with fear for six years.

Police discovered Gacy while looking into the 1978 disappearance of 15-year-old Robert Piest. Authorities found 26 young men's dead in Gacy's home's crawlspace. Three more victims' bodies were discovered on his property, while the remaining ones were discovered in the neighboring Des Plaines River.

Gacy was accused of 33 killings. His trial began on February 6, 1980. Gacy tried to use insanity as a defense but was unsuccessful, and he was found guilty on all 33 charges of murder. For 12 of Gacy's killings, the prosecution requested and received the death penalty as punishment. In 1994, John Wayne Gacy was put to death by lethal injection.

2.Ted Bundy:The most infamous serial killer of the 20th century was arguably Ted Bundy. The actual number of victims may be far greater despite the fact that he acknowledged to killing 36 women.In 1972, Bundy received his degree from the University of Washington. Bundy, a psychology major, was referred to by his peers as a superb manipulator. By pretending to have injuries, Bundy attracted his female victims before overwhelming them.Bundy's murderous rampage spanned several states. He repeatedly managed to get away from authorities. With his 1979 murder conviction in Florida, everything came to a stop for him. Bundy was put to death in the electric chair in 1989 following a number of appeals.

3.David Berkowitz: Son of Sam:In the 1970s, David Berkowitz (real name Richard David Falco) terrorized the New York City region by killing a number of people brutally and seemingly at random. Berkowitz, also known as "Son of Sam" and "the.44 Caliber Killer," confessed to his crimes in letters to the police and the media.On Christmas Eve in 1975, Berkowitz is said to have stabbed two ladies to death with a knife. However, he is most known for approaching parked cars and killing his victims. He had already killed six people and injured seven more before he was apprehended in 1977.When Berkowitz admitted to the six killings in 1978, he was given a 25-year to life sentence for each one. In his confession, he said that a devil had visited him in the appearance of Sam Carr's neighbor's dog and given him the order to kill.

4.The Zodiac Killer: Unsolved:The Zodiac Killer, who stalked Northern California from the late 1960s to the early 1970s and left a trail of dead victims behind him, is still a mystery.A string of letters were sent to three newspapers in California in this strange case. An unidentified murderer admitted to the killings in many of the letters. The threats he made that he would commit murder if his letters were not published, however, were far more terrifying.Not all of the letters, which continued until 1974, are thought to have been written by the same person. In the high-profile case, police believe there may have been other copycats. 37 murders were admitted to by the person who became known as the Zodiac Killer. Police can only confirm seven attacks, five of which resulted in fatalities.The Keddie Cabin murder case, a comparable California cold case, has been unsolved since 1981.

5.Charles Manson and the Manson Family:

Charles Manson, a charismatic vagabond with visions of rock and roll grandeur, forced a number of young people to join "The Family" in the late 1960s, many of whom were impressionable teenagers.The most notorious killings committed by the gang happened in August 1969. A number of Manson's "family members" broke into a home in the northern hills of Los Angeles on the evening of August 8 under his direction. They murdered five individuals throughout the course of the evening and early the next morning, including Sharon Tate, the wife of director Roman Polanski, who was eight and a half months pregnant at the time, and Abigail Folger, the wealthy Folger Coffee heir. Leno LaBianca, a supermarket entrepreneur, and his wife Rosemary were killed the following night as part of the Manson family's ongoing murderous rampage.
