Lit cigarette triggers house explosion after bullet pierces gas pipe

The explosion was strong enough to send two doors from the home into the street and shatter windows.

Neighbor Daniel Lyons told WDIV-TV that he heard the explosion from a block away.

Investigators determined that a someone had fired a weapon in the home and the bullet pierced a basement gas line. The leaking pipe eventually filled the basement with gas and when a woman in the home lit a cigarette an hour later, ignited the gasses.

A dog also survived the explosion and is expected to make a full recovery.
