A neighbor shared Ring video of the house explosion.

Neighbors, who had damage to their homes as well, told CBS 11 there was a lot of lightning and thunder, then a boom.

"All of the sudden I heard what I thought was my sliding glass door breaking," said neighbor Caroline Klobas. "And I just noticed two picture frames on the wall fall down and the sound and that didn't match up. When my husband pulled into our garage, the roof in our garage had caved in."

"It's gone," a police officer said about the house to CBS 11's Andrea Lucia as she arrived on the scene.

Plano Mayor John Muns said, "We are saddened by today's tragedy of a house explosion in our city. Several of our residents were injured.
