The fiancée of a Westfield High School principal who died after donating bone marrow to a student in France has filed a wrongful death lawsuit.
Sheronda Braker's lawsuit filed Monday names Hackensack University Medical Center.
Westfield High School Principal Derrick Nelson, 44, died back in April, several weeks after lapsing into a coma during the procedure.
Nelson, who had a 6-year-old daughter, didn't know the French teen but wanted to help nonetheless.
Nelson and the teen were connected through Be the Match, a worldwide bone marrow registry network.
Nelson also served as an officer in the Army Reserve for more than 20 years and had recently re-enlisted.
The hospital didn't immediately return a message seeking comment on the lawsuit Monday.
