Roommate said: she heard noises coming from the room that Madeline and Sterns shared.
The room Madeline and Sterns shared??? Sharing a room, such that others even noted it was a shared room, vs MS sleeping with SS on the nights JS wanted extra sleep. Not the same thing!
He was never JS's boyfriend.
The roommates warned her, her family warned her, but JS did not want to know. When interviewed (p.73), she said she couldn’t remember how many times she let MS sleep alone in SS’ bedroom. “Jennifer stated she allowed it because she trusted Stephan, and he treated her as his daughter.” She either lived the last years in complete denial or she enabled and allowed.
