Baltimore police may have charged the wrong suspect in the crime of disabling city cop cars last week.

A Baltimore Sun blogger is now reporting that the gasoline supplier, IsoBunkers, conducted its own tests and “found the gas was 10 percent ethanol — just what it was supposed to be.”

In a story that went nationwide, Baltimore city officials blamed an ”unusually high amount of ethanol in gasoline” when over 200 police cars experienced engine problems after fueling up at a city-run pump.

IsoBunkers officials noted that only police cars were affected by the breakdowns, not other city vehicles that used the same pump. City officials are now saying they will continue the investigation to determine exactly what did cause the problem.
