Local schools are tightening security to prevent the kind of violence that occurred in Connecticut. The massacre of elementary students in Connecticut has prompted schools in Lubbock and elsewhere to tighten security on their campuses.

Lubbock Independent School District put new security measures in effect today, earlier than originally planned. The district sent an automated telephone message to parents last night telling them all doors on campus will be locked during the school day.

The money to pay for the new security precautions comes from the 2010 LISD bonds. School staff can lock down a school by pushing a button. Lubbock Cooper ISD was placing additional police officers at each of its schools.
