WILTON - Aaron Ramsey, of Wilton, was sentenced today to 50 years in a psychiatric hospital for beating his father to death.

Aaron Ramsey's attorneys say he attacked his father at their home because voices told him that his father was an alien. Last year, a three-judge panel found Ramsey, 23, guilty of murder by reason of mental illness.

Ramsey's attorney said he had no history of violence before this incident. His mother was in court, but she was not willing to comment.
