A man who once faced the death penalty for killing a woman and two children and setting fire to their house 20 years ago is to find out next year what his new sentence will be. A judge yesterday scheduled a March 14th sentencing hearing for Rhett DePew. The 51-year-old DePew could be sentenced to three consecutive life terms or could be allowed to serve them at the same time. Butler County Common Pleas Judge Keith Spaeth is also to decide whether DePew should be eligible for parole consideration after 20 or 30 years. A federal judge threw out DePew's death penalty sentence, ruling that a prosecutor's comments in court during sentencing in 1985 made it an unfair trial. DePew was convicted of three counts of aggravated murder for the 1984 stabbings of 27-year-old Teresa Jones and two young girls at their Oxford home. Police said DePew then set fire to the house to try and cover up the killings.
