Corporal Brandon Schreiber is a five-year veteran with the Newton County Sheriff's Office.
He was shot last week after pursuing an armed suspect with a suspected hostage from Illinois. An officer shot and killed that suspect, identified as 37-year-old Andrew Roselius.
Schreiber is an organ donor, and the department says his sacrifice in the line of duty will help save others.
Police did not find a hostage inside Roselius' vehicle. Illinois State Police are investigating the shootout.
