Death masks

An idea on a style of mask we can use for the killer- a death mask. This is a cast taken from the face of a dead person, and encaptures the expression on the face when they died  

These are eerie and frightening, from a victims point of view seeing the face of death on their killer would be frightening, as they know they are about to die. Plaster casts are made to use these so we will have to experiment.
