FRINGE EVENT: Shapeshifters being systematically executed




FILE ARCHIVED BY: Grant Pollard, Lee Varner

WITNESSES/CONTACTS: Lieutenant Pike, Dr. Grant


VICTIM(S): Dr. James Falcon, Jackie Bermudez, Zach Alpert


The Machine was built on Liberty Island, but no one was able to activate it. A dozen different power sources were tried, along with multiple diagnostics, but it remained unresponsive. NASA, the CIA, the NIH, and the government's top people had no idea how to operate it. Peter Bishop turned out to be the key when his mere presence created an electromagnetic spike that triggered the Machine.
 A colleague found Shapeshifter Michael Baird dead in a fountain with his data storage disk removed. Baird was on a long list of Port Authority employees on Special Agent (B)Olivia Dunham's hard drive, and his death tipped the agency to a mole placed by Secretary Walter(nate) Bishop.

Glyph Sightings
