So I saw this report and just felt like dope slapping the reporters.
Hybrid Car May Have Sparked Garage Blaze - Connecticut News Story - WFSB Hartford

The short version is guy owns a Chevy Volt. Garage catches fire. Even though there is no evidence that the Volt caused the fire the article headline suggests the connection and a sentence in the article again makes the suggestion while taking a fire marshal's quote effectively out of context. The marshal says they can't rule it out... well at the beginning of an investigation when the garage is still smoldering of course he can't rule it out. He also can't rule out arson and a number of other "possible" causes.

The house is old, there are two electric cars in the garage (one home built) and presumably both were charging. It seems to me this news agency was really digging to add controversy to a story where none existed.
