GRAYSON COUNTY, Tex. -- Hundreds of people walk in and out of the Grayson County Justice Center every day, but it's about to become more of a task to step through those doors.

A new surveillance system will soon guard the entrance. County officials approved a $37,000, high-tech security system for the center, including x-ray machine and metal detectors.

Sheriff Keith Gary says courthouse shootings are becoming more common. One in East Texas two years ago proved deadly.

Gary and county officials say they have researched security at courthouses in other counties over the past year and a half and have now decided to implement some changes.

"There are horror stories all over the country where people have gone in and shot judges, particularly in divorce procedures, tempers flare; it's a very dangerous time. We don’t normally think it is, but it is," Gary said.

Officials say work on the new security system is expected to begin on the lobby in five to six weeks.
