I don't personally know whether it's possible, but the NYT has reported that every year a couple of people die from leaving a running car in the garage:

If it is possible to do accidentally, then it's also possible to do on purpose.

With that said, I would expect more 28 false positives 12 years. Those very low numbers may indicate that - contrary to their reporting - it is not actually possible (barring weird circumstances).
