I would also be curious if someone matching Brian’s description had been seen in any local stores that carry tarps, large plastic garbage bags, duct tape and/or rope... :(
Or he might have disposed of Gabby’s body in a remote spot or pushed her off a cliff or into a ravine. He’s had a huge head start and unless he confesses her body might not be found for years or never. Especially when you consider all the hungry wildlife out there.
