KALISPELL, Mont. -

 The Bigfork School District plans to spend $17,900 to improve security at school buildings.
    
Superintendent Cynthia Clary tells the Daily Inter Lake the district brought in three firms to do security audits and make recommendations.
    
She says the district plans to install exterior door contact wires, motion detectors and an infrared sensor system.
    
Clary says it's important for people to know that public schools are safe.
    
Officials say the security improvements are being made in the wake of the December shootings at Sandy Hook Elementary School in Newtown, Conn., that killed 20 students and six staff members.
