Tom Juby, a veteran RCMP forensic investigator assigned to the probe, said he uncovered evidence early on that suggested an incendiary device may have been planted on the plane but that he was prevented by his superiors from following up fully on the evidence and was even directed to alter his notes. After trying for the past several years to get senior RCMP officials to re-examine the case, he said he decided to go public. “My opinion is it was extremely suspicious and we should’ve continued testing,” Juby, now retired, said Wednesday in a phone interview. “I was shut down.” Juby is scheduled to appear this Friday in a documentary about the Swissair crash on the CBC’s The Fifth Estate.
