A Stamford who fatally beat his mother nearly two years ago has been admitted to a mental hospital.

A judge formally admitted Tim Anderson to the Whiting Forensic Division at Connecticut Valley Hospital for 20 years.

In 2015, Anderson punched his 76-year-old mother, who then fell into a coma and later died.

Anderson's lawyers argued he was legally insane.

He was found not guilty of murder and manslaughter back in March.
