(Aloha, OR)  --  An Aloha man is scheduled to be sentenced in January, after pleading guilty to murdering his roommate.  Thirty-two-year-old Christian Delaurentiis entered the plea Friday to a charge of aggravated murder in the stabbing death of 43-year-old Philip Lindemuth in May 2012.  Authorities say Lindemuth's body was dismembered and stored in a freezer in a garage at his home in Aloha.  Prosecutors say Delaurentiis killed Lindemuth after the victim threatened to expose Delaurentiis as a bank robber.
