GREENWICH, Conn. (AP) Greenwich school officials are beefing up school security following the shooting deaths of 26 children and educators in nearby Newtown last month.

Stricter measures in schools in the wealthy New York suburb are still being reviewed.

The Greenwich Time reports that for the first time local police will carry key cards giving immediate access to all public schools in an emergency.

Schools Superintendent William McKersie says extra visibility of officers close to schools will continue.

But school officials and law enforcement don't want to be too predictable. McKersie says officers will shift to random appearances.

In a recent letter to parents and staff, McKersie said emails from parents and staff call for improved security, with some correspondents urging armed guards.
