The Winnipeg police started following Sandham after his return, and on the afternoon of 10 April 2006, Constable Grant Goulet observed Sandham taking his Blazer to a car wash to have the interior of his vehicle cleaned. On 14 April 2006, M.H. met with Constable Timothy Diack, who told him the police knew he was involved in the massacre and he could either turn Crown's evidence or go to prison for the rest of his life. On 15 April, Sandham was observed having the tires of his vehicle removed with Sandham dumping his old tires on the side of a remote country road. An examination revealed the tires that Sandham had just abandoned in the countryside matched the tire prints found on Kellestine's farm. The next day, M.H. met with Diack, where he demanded $750,000 and immunity for testifying against the others. Eventually, it was agreed that M.H would receive total immunity, $1, 300/per month for the rest of his life, and free rent in exchange for which he would wear a wire and turn Crown's evidence. M.H. wore a wire starting from early May 2006 at his meetings with Mushey and Aravena, the latter greatly pleased at becoming a Bandido prospect, which allowed him to wear the Bandido patch. However, the "Fat Mexican" that Aravena wore had been sewed by his mother rather than supplied by Houston. Shortly after the massacre, James "Ripper" Fullager, the mentor to the "no surrender crew", died of cancer and on his deathbed complained that the Canadian outlaw biking scene had gone downhill since his youth in the 1960s, as now most "bikers" didn't know how to ride motorcycles and the outlaw biker code no longer counted with biker "brothers" killing each other. Meeting with Atkinson on his deathbed, Fullager commented it was clear that Kellestine had committed the massacre as the bodies were found close to Kellestine's farm in south-western Ontario, all of the victims except Muscedere came from the greater Toronto area, and Kellestine was still alive. Fullager noted that if the Hells Angels had massacred the Bandidos in south-western Ontario close to Kellestine's farm, they would have killed Kellestine as well.
