PITTSBURGH — A suicidal man who got the idea to blow up his house after watching a TV show about the Hindenburg explosion will spend five to 10 years in prison.

Shawn Landa, 48, of Moon Township was sentenced immediately after pleading guilty to arson, criminal mischief and other crimes Tuesday.

Landa told investigators he broke a natural gas line to a basement fireplace, turned on a gas valve, expecting something in the house would eventually ignite the gas. When that didn’t happen, Landa later ignited the gas while lighting a cigarette, destroying his home on Oct. 12, 2013.

The blast damaged nine other nearby homes.
