Sandy Hook Elementary School had informed parents on their website that they had updated their security procedures. It said:
Our district will be implementing a security system in all elementary schools as part of our ongoing efforts to ensure student safety.
As usual, exterior doors will be locked during the day.
Every visitor will be required to ring the doorbell at the front entrance and the office staff will use a visual monitoring system to allow entry.
Visitors will still be required to report directly to the office and sign in.
If our office staff do not recognise you, you will be required to show identification with a picture ID.
Doors will be locked at approximately 9:30 a.m.
Any student arriving after that time must be walked into the building and signed in at the office.
