"It's lucky that more people weren't hurt," he said. "(But) blast injuries are unique. They're not always immediate (because they can) affect organs."

The finished home, estimated to be around 3,000 square feet, is considered a total loss, Cannon said. The Ropers had been in the home a month or so, neighbors said.

The debris radius was nearly 300 feet, Cannon said, and sent a recliner onto the roof of a nearby house. Sinks, wires and pipes lay splayed across the unfinished back yard of the home and on driveways of neighboring homes.

Emily Lopez said she was driving home to Eagle Mountain when she saw the smoke. When she rounded the bend on Pheasant Lane she saw the flames and called the fire department.

"It was bad, really, really, really on fire," Lopez said.
