Did you learn the woman's age on the news? Or are we just supposing on this thread that she's old?
Collecting dead animals sounds like some sort of unrequited mothering instinct gone awry, like old ladies in nursing homes cuddling teddy bears. OTOH, the woman in question might be a retired PETA member bent on "honoring" dead animals.
The news report didn't give the woman's age, but implied that she's elderly.
