@cbsla: An investigation is underway in Yucaipa after multiple Christmas cards containing vulgar messages were left in a neighborhood overnight on Monday, leaving some residents on edge. “I pick it up, open it, and it reads, ‘Santa, I want the head of a Nazi under my tree,’” Jaret McComas, one of the residents who received one of the troubling cards, said. Doorbell camera footage from some of the homes shows masked men placing the cards, each with a different threatening message, and then blowing a kiss to the camera.
