A Colorado high school was locked down on Friday after a shooting -- just one day before the first anniversary of the Sandy Hook massacre.
La Crosse-area districts are responding to this type of school violence by taking a closer look at their own security measures.
Whenever there is an act of school violence anywhere in the nation, the La Crosse and Onalaska school districts take another in-depth look at their school security.
And while there's no perfect solution to end all school violence, there are steps the districts are taking to do their best to protect their students.
The intercom system at Onalaska Middle School is only a couple of days old. It's working to bring an extra level of security to students and teachers.
"This week we have middle school, high school and Eagle Bluff that all went online," said Onalaska School District Director of Finance and Business Larry Dalton.
Last spring, the district decided to upgrade all of its schools' security systems by adding an electric intercom entrance.
"It was quite a discussion we had before this, because obviously with this kind of system, you're not curing any possible thing that could go wrong. You can't do a system like that. There isn't one. But is this a system that the community would expect to have in a school? And I think the answer we got was, 'probably so,'" said Dalton.
The La Crosse School District is also making changes.
It also added intercom systems this summer.
District building and grounds manager Jason Showen says they also renovated the entrance to Emerson Elementary to improve safety.
"Once we're in the foyer, we've changed things so we have an open and visible effect so there's a clear line of sight with the administrative assistant or principal, and if a person tries to go directly into the building, they can't do that; the doors are locked," said Showen.
And while both districts say it's not the end-all, they say it is important to continually make changes to keep their students safe.
"There's always room for improvements. Where we've seen gaps in other school districts, we've tried to make changes as well," said Showen.
"We always have to stay attentive to what we can do to make it a safer place," said Dalton.
Onalaska School District officials say they plan to continue to add more electronic entries at their schools.
They say it's taken longer to get the system up and running than they planned because the parts were on back-order because so many schools and businesses are adding the security feature.
The La Crosse School District is also planning to add more security cameras to its schools and make upgrades to the system.
