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.

Although the cards appear to bear typical Christmas messages on the outside, several neighbors were disturbed upon opening the letters left on their doorsteps in the neighborhood near Wildwood Canyon State Park.

"I pick it up, open it, and it reads, 'Santa, I want the head of a Nazi under my tree,'" said Jaret McComas, one of the residents who received one of the troubling cards.

Each card came with a different violent or threatening message, including one card that simply read, "You are warned." Another said, "Merry Christmas and f— you Nazi."
