A Madison man has been deemed competent to stand trial for allegedly stabbing his roommate to death.  Ronald E. Redeaux Junior made a Dane County Court appearance Monday.  He had been found not competent in January.  Madison police say Redeaux told them he used a pair of scissors to stab 52-year-old Gerald Moore multiple times and Moore was dead when officers arrived.  The two men had been roommates, on and off, for about six years.  Redeaux faces a charge of first-degree intentional homicide.  His court date hasn’t been announced.
