Jonathan Scott Chacon was found guilty last month of two counts of first-degree murder in the February 2012 killings.

Torrance Superior Court Judge Steve Van Sicklen sentenced Chacon to two consecutive life terms without parole, plus two additional years in prison for using a knife to kill his girlfriend, Courtney Bergman, 19, and Vicki Bergman, 59, according to the Los Angeles County District Attorney’s Office.

Chacon had claimed he acted in self-defense when he killed the women.

Chacon fled to Mexico after the Feb. 28, 2012, killings but was soon arrested.

He testified that he and Bergman liked to use a knife as part of sexual foreplay, the Daily Breeze reported last month.

On the night of her death, after the couple had sex, Courtney Bergman had become angry at Chacon and came at him with a knife, the defendant said.

He felt like he was in a trance, he said.

“I was able to get the knife away from her. My instincts took over and it ended how it ended … with me slicing her throat,” Chacon said, according to the Daily Breeze.

When Vicki Bergman emerged from another room to see her daughter being killed, Chacon turned on her.
