Police came to pull a Jeep out of a lake. They found a woman inside, alive

This black Jeep was almost entirely submerged in Lake o' the Pines in Marion County, Texas. It wasn't until a tow truck started to pull it from the water that a woman was spotted inside. (Marion County Sheriff Office)

It started with a call from a fisherman, who said he saw what looked to be a black Jeep virtually submerged in a large lake in Marion County, Texas. Not until later, after a tow truck came, did anyone realize someone was in the vehicle — and that they were still alive.

"We do not know how long the Jeep was in the water," Capt. Chuck Rogers, an investigator at the Marion County Sheriff's Office, told NPR. And that's just one of several questions that remain unanswered about the unusual case.
