Mullenix was accused of getting former boyfriend Ian Allen to help her murder her mother, Barbara Mullenix, in her Huntington Beach condo in 2006.
Jurors found Mullenix, 19, guilty of first-degree murder on the fourth day of deliberation. They did not give her a sentence enhancement for personal use of a deadly weapon, which means they didn’t see proof she actually stabbed her mother.
Mullenix entered the courtroom sobbing. When the verdict was announced, she wailed convulsively and collapsed face-first on the table. “It’s not right,” the teen’s grandmother, who declined to give her name, said through tears as the verdict was read.
During the weeks-long trial, Mullenix had testified she loved her mother as her “best friend,” but planned to run away from an unstable household with Allen after Barbara Mullenix threatened to keep them apart. As she told it, Allen got into an argument with the mother the night they tried to leave, but the teen was shocked to see him stabbing her mother violently. Mullenix testified she helped him clean up and dump the body because she was “in shock.”
But prosecutor Sonia Balleste called her a manipulator who used emotional tricks to enlist Allen to help her stab Barbara Mullenix more than 50 times with multiple knives. “I think she hates her mother,” Balleste said to reporters after the trial. “In my opinion, Rachael Mullenix is a sociopath.”
Cohn said he still believed his client’s story.
“The evidence in this trial from the defense perspective is everything I know about this case,” he said. He said he didn’t know about any appeals Mullenix might make, as he wasn’t an appeals lawyer and wouldn’t be handling them.
