Cars with skeletal remains found at bottom of Oklahoma lake

The two rusty, mud-caked cars that Oklahoma officials stumbled onto at the bottom of a lake, where they found six skulls and skeletal remains, sat 3 feet apart under 12 feet of "super murky" water.

To add to the mystery, officials say, the cars might have gone into the water a year-and-a-half apart, more than 40 years ago. (Good Morning America)
