Corporal Jeffrey Walraven suffered a heart attack while on duty at the Community Corrections Center-Lincoln (CCC-L) on Jan. 1.
Sergeant Keisha Silas directed team members to activate Emergency Medial Services (EMS) while she stayed by Walraven's side. Walraven recently presented Silas with a challenge coin to show his appreciation for her brave actions. 
The Nebraska Department of Correctional Services (NDCS) thanks Silas and all team members who assisted Walraven during this time.
