A Warner Robins, GA, police officer is getting a potentially life-saving kidney transplant from a man he once taught.

Porter Wood has a rare disease that attacks the kidney’s filtering capacity.

The 26-year veteran of the police force needs a kidney transplant, and he didn’t have to look past the roster of city workers to find one.

One of Wood’s former DARE students who is currently a city employee, Trey Ammons, is a match and will donate his kidney for a transplant June 23 at Piedmont Hosptal in Atlanta, the Macon Telegraph reports.
