(Salem, OR)  --  A man convicted of murdering another man following an argument at a bar is facing life in prison.  A Marion County judge sentenced 27-year-old Darnell Harris yesterday to life without the possibility of parole for 34 years.  Harris pleaded guilty last month to stabbing 32-year-old Andrew Ramos to death in November of last year.  Harris also pleaded guilty to tampering and soliciting murder for attempting to order a hit on a witness to the stabbing while behind bars.
