Hole opens in home, swallows man

Authorities say the home, built in the 1980s, may have been sitting atop a decades-old underground mine. Recent rains could have softened the ground under the home, in an isolated area near Lake Alta.

"It's unbelievable," Placer County Sheriff's Department spokeswoman Dena Erwin said. "From the front of the house, it's absolutely normal. Then, in the middle of the house, is this enormous hole."
