Gareth Pursehouse, 41, was re-arrested on a no-bail warrant and charged Wednesday with the murder of his ex-girlfriend, family and sex therapist Amie Harwick.
He was also charged with first-degree residential burglary with the special circumstance allegation of lying in wait and is eligible for the death penalty if convicted, per NBC News and Deadline.
He's to enter a plea on Thursday, according to the Los Angeles County District Attorney's Office, which has yet to decide if it will seek the death penalty.
