The city of Champaign is getting ready to unveil a community crisis response plan that aims to help people in the days and weeks following an incident of community violence.

This week, the Family Service Self-Help Center of Champaign will host a conference focused on the importance of working together to address needs in the community.

Researchers who study community violence have identified trauma as one of its main underlying causes. And it’s a vicious cycle: trauma spurs violence, which causes more trauma to the community. A free training program aims to equip participants with the tools they need to help victims of trauma.

A male student opened fire inside a central Illinois high school cafeteria Wednesday, wounding one other student before being restrained by a teacher, according to police.
