 At the same time, Bouchard had two detectives, Louis-Marc Pelletier and Michel Tremblay, painstakingly go through all of the old evidence from unsolved murders such as hairs, skin flakes found on guns and disregarded Kleenexes, and spit to see if there were any DNA samples that could be recovered.Peletier and Tremblay were able to recover four samples of DNA from the old evidence and then using the DNA found from coffee cups and the like, were able to link four Hells Angels/Rockers, most notably Wooley to the murders.By February 2001, Bouchard's team had assembled enough evidence that they were prepared to lay 23 charges of murder, attempted murder, conspiracy to commit murder and gangsterism against 42 Hells Angels or Rockers.
