Serial Killer: The case of Dana Sue Gray.

The people living in Canyon Lake, a community in California knew a dangerous person living in their midst. Her name was Dana Sue Gray.

The first person she killed was 86-year-old Norma Davis. Dana Sue had visited Roberts one day claiming she wanted to borrow a book about controlling a drinking problem. February 28, 1994, her body was found by Norma's neighbor, Alice Williams. Norma had a wood handled knife sticking out of her neck, and a fillet knife sticking out of her chest. Other than a broken fingernail, she had no other marks. A bloodied afghan lay at her feet. She had been dead for two days. Norma was the mother-in-law of the woman (Jeri Davis) who married Dana's father in 1988. She was Dana Sue's step-grandmother.

A serial killer without a heart: Jeffery Dahmer

Jeffrey Dahmer was an American serial killer and sex offender, born on May 21, 1960. Between the years of 1978 and 1991, Dahmer murdered 17 males in truly horrific fashion. Rape, dismemberment, necrophilia, and cannibalism were all parts of his modus operandi.

Hollywood's Murder Mystery: Who Killed William Desmond Taylor?

On Feb. 1, 1922, William Desmond Taylor was enjoying a rich, full life. The midde-aged man had achieved much of which he could be justly proud. In that silent film era, he was one of Hollywood’s most successful and respected directors. He had directed such acting greats as Mary Pickford, Dustin Farnum, Wallace Reid, and Mary Miles Minter. His notable films included Davy Crockett, Tom Sawyer, and Huckleberry Finn. He had recently directed The Green Temptation starring Bett Compson. Just prior to that, he had directed Anne of the Green Gables. Both motion pictures had been well received (perhaps green was a lucky color for him) so he could look forward to directing many more movies.

At 10:30 AM on the morning of Monday, December 16th, 1935, Mae Whitehead approached a garage where she was supposed to drop off her personal car and pick up the Lincoln Phaeton belonging to her boss, 29-year-old actress Thelma Todd. Mae was Thelma’s trusted maid who was tasked with picking up Thelma’s car each morning and bringing it down to Thelma Todd’s Sidewalk Cafe, the restaurant Thelma owned and lived above with her boyfriend at the time, Roland West. Mae noticed absolutely nothing unusual about the scene until she saw her boss slumped over in the car’s front seat, still wearing the same clothes she had been wearing on the night of December 14th when she went to a party at Hollywood’s legendary Trocadero nightclub.
