Ericka Elwood-Woolum is a character mentioned in Fallout 4.
Ericka was a scientist working at the Cambridge Polymer Labs. She was also the wife of Jon Elwood, the director of the establishment. When she tried to gain access to room C3 along ventilation pipes, she was killed by a rigged gun.
Investigating the scene, one can find a pipe pistol on the floor, beneath the broken up ceiling plating. It may well have been attached to the ceiling wire, firing when the plate was removed.
Ericka Elwood-Woolum is mentioned only in Fallout 4.
