HARTFORD, Conn. (AP) -- The governor of Connecticut is calling for flags to fly at half-staff to mark the second anniversary of the shooting massacre at Sandy Hook Elementary School.

Gov. Dannel P. Malloy's office says flags are to be lowered Sunday from sunrise until sunset in honor of the 20 first-graders and six educators killed at the school Dec. 14, 2012.

The gunman killed his mother inside their home in Newtown before driving to the school and shooting to death 26 people with a semi-automatic rifle. He committed suicide as police closed in.

The town of Newtown is not holding any public commemorations Sunday. Local officials say the day will be marked through personal reflection and remembrance.
