HENRIETTA, N.Y. — Two teenagers were injured in a Henrietta house fire Thursday morning.

This home started burning on its first and second floors just before 10 a.m. on Wildbriar Road, off East Henrietta Road.

Investigators have yet to determine what started the fire. 

The most seriously injured resident suffered burns to his face, chest and arms.

The other teenager suffered smoke inhalation.

 Two other children escaped the home and were treated on scene.

"There is nothing that is obvious to us at this point," said Melanie Funchess, Mental Health Association of Rochester/Monroe County. "Monroe County Fire Bureau is on scene to do an origin and cause investigation."

The house was so badly damaged, authorities expect it to be torn down.
