- "We were at a campsite about eighty miles south of here, coming back from Florida... The news hit us a little late...We didn't even know what was going on. My wife... Never left that campsite."

Not much is known about Erma's life before or as the outbreak began, apart from she was married to Dale and was traveling across America.
Hardly anything is known about Erma after the outbreak except that she was bitten by zombies within the early stages of the outbreak, succumbing to the infection soon after. She was buried at the campground she and Dale were staying at when she died.
- In the TV Series, Erma's name is changed to Irma Horvath, as seen on the side of Dale's RV by the door. Also, in the TV Series, she died of cancer two years before the outbreak.
