Some More Questions
Apparently, voice manipulation software is used within the on-line gaming community to fool opponents and/or to enhance their characters/avatars. It looks like the software can be use to convey emotions, make a voice sound like a different gender and even sound drunk. Could the perp be a gamer?
I'm sorry...the following question is gross! Did anyone notice the presence of carrion eaters (particularly the flying variety: herring gulls, hawks, falcons, owls, osprey, eagles, harriers) where S.G.'s remains were eventually found? With the remains so close to the highway (no gawker slow downs?) so close to residential areas in possibly turbid water; wouldn't sanitation, ecology and/or wildlife management personnel have noticed the presence of carrion eaters and at least taken a look see? That is if S.G.'s remains were where they were found the whole time intact.
If the perp is a digital and physical voyeur/stalker/peeping tom and has been spying on Long Island community members, could he have used the the information gathered to determine who would be away from home for a while and use those homes to perpetrate his crimes?
