The mother of the 16-year-old boy who jumped from a moving school bus Friday morning says that her son has died.

Ann-Marie Herr told Channel 4 that Jessie Herr’s organs are being harvested for donation today. 

She was told Friday afternoon that his brain stem snapped from the fall.  He was pronounced dead at 3:47 p.m.

He was put on life support at Shands Jacksonville Medical Center but had no brain activity.

Mrs. Herr says she doesn’t know why her son jumped while the bus moved along the Intercostal Bridge on Beach Boulevard.  The family may make a statement later, but they are now making funeral arrangements.

Amy Reese, with the nonprofit group LifeQuest, tells Channel 4 that it takes two doctors to declare a patient brain dead.

The parents of those younger than 18 make the final decision on donating the organs, even if the person is already a registered donor.

After the decision is made, the person’s body is kept on a ventilator to preserve the organs and tissue and evaluate if the donation can be made.
