Friday, Jan. 15: Mystery at Empire Lake

A mother of four disappears, vanishing in the night from her family's property on a vast wilderness. The next morning, they found her car at the foot of the driveway, but no body, no murder weapon, and no witnesses. You might think there wouldn't even be an arrest, let alone a trial. But there was a trial... and that's when things really got strange.

NBC's Keith Morrison goes inside The Mystery at Empire Lake.

See it all in this Friday starting at 9 p.m. ET, 8 p.m. CT.
