What is the evidence of callous disregard for human suffering in an assault case where an assault victim was taken to a remote part of the country by his ex-partner's partner, who was not charged for the assault?

him to a remote area, allowed him to prepare himself, and then savagely attacked him, breaking his nasal bone, jaw bone, and an orbital bone under one eye and inflicting lacerations to his face and scalp which were serious enough doctors treated them with staples. The potential for prejudice was greater because appellants were not prosecuted for the beating, tempting the jury to convict them of the charged offenses to assure punishment for the uncharged offenses. (People v. Balcom, supra, 7 Cal.4th at p. 427.) We conclude this evidence of callous disregard for human suffering is extremely inflammatory and should have been excluded on prejudice grounds, especially in view of its limited probative value.
