CHARDON, Ohio - One year ago, a deadly school shooting left a small town in shock when three high school students were killed and three others wounded.

Staff and first responders joined the student body of Chardon High School Wednesday for a memorial walk in honor of Danny Parmertor, Russell King and Demetrius Hewlin, the students killed. At the town square, they were met by members of the victims families and a huge crowd of well-wishers.

For many it was very emotional to recall the tragedy of that day. Members of the senior class thanked the community for all the support over the past year.

"Nothing will ever be able to make up for the loss of Danny, Russell and Demetrius, but I'm so honored to be a part of a community that has responded so well and come so far in a year," one senior boy told the crowd.

The high school principal, Andy Fetchik, said coming together has made everyone stronger.

"I think we've rallied around togetherness in knowing that there's people there for us, to know that we have each other," Fetchik said.  

In the wake of this tragedy, the school superintendent said the silver lining is that students now know the importance of alerting someone if they see suspicious behavior by another student.

"They've learned and quite frankly been given permission and given themselves permission to tell people something is wrong, and that is the key factor is school safety," said Superintendent Joseph Bergant.

The shooter, T.J. Lane, who fired ten shots into a group of students is awaiting sentencing after changing his plea on Tuesday to guilty on all charges.

He could face life in prison, but not the death penalty because he was only 17 years-old at the time.

Fetchik said there is still another sad day ahead for the school and the community because there will be three empty chairs at graduation this year.
