Wilton police say they have arrested a man who has confessed to killing his father with a screwdriver last night. Authorities say 22-year-old Aaron Ramsey repeatedly beat his father, then stabbed him several times before fleeing his Signal Hill Road home. They say he then entered a house on nearby Cheese Spring Road and refused to leave unless paramedics took him to the hospital. The victim, 73-year-old Ed Ramsey, was found dead when police arrived. Ramsey has been charged with murder and was arraigned today in Norwalk. Court documents indicate he heard voices in his head that told him to "put people on trial" and that he stabbed his father with a knife after he was already dead. Police say Ramsey had previously been arrested for DUI and possession of marijuana. He is being held on bond and has been ordered to undergo a psychological evaluation.To hear the 911 call from the Wilton homicide, click on iO Extra on Channel 612.
