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-Woolum, 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.
