A kindhearted US high school principal has died after suffering complications following a bone marrow donation.
Derrick Nelson underwent surgery in an attempt to save the life of an ailing 14-year-old boy in France.
According to CNN, he suffered a complication and slipped into a comma afterwards.
His family said ever since February, Derrick was unable to speak or move but could recognise the people around him.
"We really do not know the full story of what happened. We were expecting him to come out of the coma he was in. But he did not make it," his father said.
The principal had no idea who the recipient was.
The father of one was contacted by Be The Match, a bone marrow donation programme that notified him that his blood matched that of ta e sick boy.
Without any hesitation, the educator said it was worth going through the procedure to give the little boy years of happiness.
Derrick was convinced the operation would be simple and not life-threatening.
"He was a tremendous father to our beloved daughter Morgan and the best companion and life partner I could have ever asked for," his fiancé, Sheronda Braker, said.
Before the procedure, the kind man admitted to having the sickle cell trait and suffering from sleep apnea.
The procedure was done under close monitoring by doctors as they did not want to risk putting him under anaesthesia.
He was described as a selfless person who went above and beyond for the community.
