However, Facebook provides us with some clues. Among the friends listed on Kurcz's page are a couple with the last name "Sher" -- the same as Josiah Sher, one of the men already arrested. Sher, Micah Woody, Matthew Plake and Christopher Wells all worked for Rocky Mountain Auto Brokers. Wells and Plake had been fired prior to the slayings, but Sher and Woody still worked there, and are said to have shown up at the lot looking "rough." Indeed, Sher reportedly had scratches on his face.
By the way, Josiah Sher's Facebook page has been pulled down, but cached links connect it to a number Shers on the Kurcz page. Could Kurcz, whose LinkedIn profile refers to her as an "independent cosmetics professional," have been Sher's girlfriend?
