(Portland, OR)  --  Officials say an inmate who died in the Multnomah County Detention Center doesn't appear to have been a victim of foul play.  The body of Lloyd Milton Virnig of Sandy was found in his cell Friday.  An autopsy was conducted Saturday, but cause of death still hasn't been determined.  Officials say Virnig had been booked into the jail Thursday on multiple counts, including heroin possession, first-degree burglary, and fraudulent use of a credit card.
