That case of human remains found on a snowmobile trail near Parry Sound continues to get stranger by the day.  After the remains were found Sunday night, OPP arrested a man on Tuesday and charged him although they didn`t say with what.  Now comes word that this man has died but even those details are shrouded in mystery.  West Parry Sound OPP are mum on if the man died while in police custody and they`re not saying how he died.  They`re only saying he`s a 34-year-old from Mississauga.  Normally when a person is hurt or dies and police are involved, that triggers a probe by the Special Investigations Unit.  But nearly a day after releasing information that the accused has died, there`s still no word on whether the SIU will take over the case.  Meanwhile, a pathologist in Toronto continues to examine the remains found on the snowmobile trail.
