Parker County Jail

A Texas teen says a Halloween movie inspired him to shoot his mother and sister to death after watching the main character in the film murder his family "with ease and with little remorse."

Jake Evans, 17, wrote a chilling four-page confession for the killing of his mother Jamie Evan, 48, and his younger sister, Mallory, 15.

Jake writes in his confession that after watching Rob Zombie's 2007 remake of the horror movie "Halloween," he lured his sister out of her room and shot her multiple times. He then killed his mother.

"While I loaded the gun back up, I was shouting that I was sorry and then ran fast as I could to kill her. I made sure my mom was dead and shot her again in the head," Evans wrote in a Parker County Police statement.

From there, Evans planned to kill his grandparents at their home across the street along with his older sister who was visiting from college.

"My plan was to kill my sister and my mom at my house and then go over to my grandparents and kill my oldest sister Emily and my two grandparents," Evans wrote, but he had a change of heart and called 911 instead.

Evans killed his mother and sister with a .22 revolver he stole from his grandfather.

""After a while I thought to myself that if I were going to kill my mom and Mallory, I wouldn't want them to feel anything. So I decided to kill them both with the .22 revolver I stole from my Grandpa," he wrote in his confession.

The murders shocked the small community of Aledo, Texas. In a disturbing 20 minute 911 phone call, Evans tells the operator he killed his mom and sister because people are "rude to each other" and he felt his family was suffocating him.

"I don't know, I'm pretty, I guess, evil. Whatever, I'm sorry," Evans said. "I just thought it would be quick, you know? I didn't want them to feel any pain. That's why I used a gun, but it was like everything went wrong."

Prosecutors introduced Evans' statement into evidence during a pretrial this week.

He has been charged with capital murder, according to court documents, and is being held without bond.
