PLANO, Texas (CBSDFW.COM/AP) – A gas leak in a Plano home Monday, July 19, was the likely cause of an explosion that destroyed the house and heavily damaged the two next door, injuring six people, fire officials said Tuesday.

Plano Fire-Rescue said further investigation would be needed to determine where in the home the leak happened before the single-story house exploded around 4:40 p.m. on Monday.

A Plano Fire-Rescue spokesperson said the leak could have come from an appliance or anything else, adding the destruction will hinder the investigation.

The leak was isolated to the home that exploded and no other homes are in danger, Plano Fire-Rescue said.

A couple with three young children had just moved into the neighborhood about a month ago.

The three boys have been released from the hospital to their grandmother, according to a family friend.

The friend said the husband had to have emergency surgery to remove glass and debris from his body.

The community is raising money to help the family and a GoFundMe account is set up.
