Officials initially determined Harrington died from natural causes, but several days later an autopsy report corrected them, pointing instead to carbon monoxide poisoning.

Incident reports would later reveal Harrington inadvertently left his 2011 Chrysler 300c running in the first-floor garage. The car produced so much carbon monoxide it depleted the available oxygen in the garage and the car stalled, but not before deadly fumes traveled three floors up and seeped into Harrington’s bedroom. He died in his sleep March 19, 2012, the victim of a simple oversight that didn’t have to be fatal. More here.
