Well, more like an ex-ostrich mystery:

When dispatchers called Trooper J.J. Creech to check out a big bird strutting down N.C. 39, he thought it probably was a chicken loose in the morning fog.

He chuckled as he turned his cruiser north to chase the poor critter off the Johnston County highway before somebody hit it.

But sure enough, Creech spotted an obstinate ostrich -- tall enough to peer over the roof of his patrol car.
...
Then out of the fog came a yellow Ford pickup...

Thing is, according to the article anyway, nobody in the area farms the things, and the nearest zoo is miles away. I wonder if it tastes like chicken?
