(Portland, OR)  --  Police say there may be a connection between the shooting death of a Lake Oswego woman and a man's suicide.  Thirty-six-year-old Mitra Mehrabadi was found dead in the Liberty Centre on Northeast Holladay Street in Portland around 7:40 Saturday night.  Earlier in the day, police say they heard a gunshot from inside a vehicle parked on Northeast 19th Avenue, and found 51-year-old Jimmy Alan Morgan dead.  Investigators say Morgan and Mehrabadi were co-workers at Liberty Mutual Insurance in the Liberty Centre.
