PORTLAND, Ore. (KOIN) — Despite the discovery of the bodies of the younger two Martin girls, the official investigation has been shut down. The disappearance of the Martin Family has been ruled a tragic accident.

So, why was someone inside the Martin home after they, according to the official report, drove into the Columbia River, but before anyone knew they were gone?

Now Multnomah County Det. Walter Graven must work on his own, trying to put the pieces together and keep the story alive with the hopes that someday, someone will crack the case.
