John Montorano, a neighbor, told emergency responders that he heard a loud bang and saw Zachary on the ground. He rushed outside, doused the fire, and called 911, Yizzi said.
Yizzi said Montorano had "found a friend for life." He added, "I'm going to be taking him with me wherever I go."
Emergency medical technicians from the Cherry Hill Fire Department delivered three shocks from an automated external defibrillator to restart the boy's heart before transporting him to Cooper University Hospital in Camden.
William Hughes, the boy's doctor and director of the Temple University Hospital Burn Center, said Zachary was very lucky to have received such quick care.
One-third of Zachary's body - his back, the back of his legs, and his right arm - was burned, Hughes said. The boy was later transferred to Temple, his breathing controlled by a ventilator.
On June 15, the doctor operated on Zachary, grafting skin to the burned areas.
Zachary's parents said the family had received an outpouring of support from relatives, friends and coworkers.
Being struck by lightning is rare in this part of the country, Hughes said. About 80 people in the United States die from lightning strikes in a typical year, he said.
