A 22-year-old Wilton man has been arraigned on a murder charge in the beating and stabbing death of his 73-year-old father.

Aaron Ramsey was arrested Thursday after police responded to a report that a man covered in blood had run into a home on Cheese Spring Road and gone to sleep on the floor.

Police later responded to the Ramsey family's home, where they found the father, Edward Ramsey, dead of multiple injuries.

Authorities say Aaron Ramsey acknowledged attacking Edward and told them he heard voices that said his father had magic powers and could heal himself.

Police say the younger Ramsey said he ran away because aliens were chasing him.

A Superior Court judge Friday kept Ramsey's bond at $1 million and ordered a mental health evaluation.
