We know that it can't be Ryan, as he wasn't outside the Carroll home until the following night. We think it's ultimately that wandering old man with dementia who Mare tackles late one night. But we still don't know for certain who the actual ferret man is.
A week or so later, the camera is operational when Mare returns after a neighbor kid vandalizes the Carrolls' property-and months later, it helps Mare break the case by revealing that Ryan Ross had stolen Glenn's gun, the weapon used to shoot Erin. Mare, frustrated because this task is below her pay grade, listens as Betty describes the prowler as a hoodie-wearing man who looked like a 'ferret,' which Mare can't corroborate because the granddaughter has already left town and Betty's absent-minded husband, Glenn, hasn't set up the security camera properly. Betty Carroll calls Mare early in the morning to report a creepy dude her granddaughter saw in the backyard. The show opens with an incident that initially seems like a way to indicate just how boring Mare's job can be and how tight the Easttown community is.
