We finally have positive identification on the creep who released those taunting videos on the anniversary of Maura's
Olson is well known to police in the area of Greenfield, Mass and Chatham, though his last known residence was Hadley. A few years ago Olson was charged with threatening to murder a relative. He frequents online chat rooms, specifically the Topix community, and has posted threats under the handles Dirtbag, Beagle, and Storagehead.
The reason for his obsession with Maura Murray's disappearance remains unclear.
