The Christmas Spree Killings was an event perpetrated by the criminally deranged Leigh Emerson, dressed as Santa Claus. It took place on December 19, 1962.
Five days before Christmas Eve, Leigh Emerson killed a man working for charity dressed as Santa. Hours later, he broke into a family's home and tied them up with their own Christmas lights before shooting them. Emerson continued his rampage, killing a total of eighteen people from five families.
Mr. Lancaster was the father of Susie Lancaster and husband of Rhonda Lancaster in Unholy Night. He was held at gunpoint by Leigh Emerson and eventually murdered by him, along with his wife and presumably their daughter.

The santa was collecting charity outside of a store in Unholy Night. He promised the young boy he would get the hat he wanted if he was good. When Leigh Emerson showed up, the santa was gunned down by him.
