Ethan Holder, the 19-year-old substitute teacher who was shot in the head and killed near P.S. 203 last week, has saved lives after his tragic death.

Officials say Holder was an organ donor. He has saved the lives of six people across four different states in their 40s and 70s who were in need of an organ donation.

The suspect in the shooting has been identified as 19-year-old Javier Oates. He is facing a slew of charges that include murder and criminal possession of a weapon.
