On Halloween night 2004, a knife-wielding intruder attacked and killed two roommates — Adriane Insogna and Leslie Ann Mazzara — inside their Napa, California home, leaving another lucky to be alive. Although the story is reminiscent of the plot of a horror film, the terror was all too real.

The night of the slaying, the third roommate, Lauren Meanza, was asleep downstairs when was woken up by a commotion in Insogna's bedroom. When she made her way upstairs to investigate, she was met with a bloody scene and fled the house to call 911. Investigators ultimately tracked down the unsuspecting killer whose DNA tied him to the crime scene.

The night of Halloween 2011 became a real-life horror story when police discovered beloved mother of four Kathleen McGehee murdered at her home in Manteca, California. McGehee had been stabbed 10 times in the torso, and the killing was "excessively violent," according to officials.

As authorities dug deeper into the brutal slaying, their investigation turned into a case populated by demons, masks, and a potential psychopath on the loose, and the community panic only intensified. 

In the suburbs of San Jose, California on Halloween night 1984, a man in a wolf mask used a machete to savagely hack apart local resident Doreen Erbert, who was eight months pregnant at the time. 

Sometime around 9:00 p.m., there was a loud knock on the front door of Erbert's home, and when she opened the door, the masked man said, “I’m going to kill you,” according to her 4-year-old daughter, Deanna Scott (née Erbert), who was present for the attack.

When officers arrived, they found a wolf mask at the scene and a trail of blood leading all the way down the block, which eventually led them to the killer.

After a massive Halloween bash at a farm in Frenchtown Township, Michigan ended with a young woman’s mysterious disappearance, the small community feared that evil was stalking its fields. Chelsea Bruck seemingly vanished without a trace on Oct. 26, 2014, and it wasn't until several months later that investigators learned of her fate.

The 22-year-old had been beaten to death with a blunt object, and DNA on her handmade costume of "Batman" villain Poison Ivy led investigators straight to her killer.

Gloria Villalta and Jose Lara.

As Halloween 2011 approached southern California, family of three Gloria Villalta, her daughter, 15-year-old Cynthia Alvarez, and Alvarez's stepfather, Jose Lara, mysteriously went missing. While Lara was later found buried in a vacant lot in Long Beach, Villalta was discovered in a different lot in the city of Norwalk. 

During their search for answers, investigators unearthed a series of haunting messages in a notebook at the family's home that pointed them right to the prime suspects.
