Neighbor Patricia Chico and police say the bolt of lightning hit a tree, ran through the ground, and struck Arlene Vancamp as she sat on a metal chair outside her home on Center Street.
"It shook my whole house, scared me to death. It just shook. I just hope she's OK," Chico said.
Vancamp's husband was also outside, but uninjured.
Neighbors say he was putting a tarp on the family pickup when the lightning hit.
Medics arrived within a couple of minutes and Vancamp was rushed to Cooper University Hospital.
Vancamp then transferred to Temple University's burn unit.
Chico says the bolt created a smoldering hole after exiting the ground.
"She was awake, alert, but she couldn't talk, her color was not well," Chico said.
