As it turns out, a lot of people. According to the latest American Community Survey, nearly 630,000 occupied households lack complete plumbing facilities, which means that they are without one or more of the following: a toilet, a tub or shower, or running water. The Census Bureau says that the average household contains 2.6 individuals, which means that today, in 2014, in the wealthiest nation on Earth, upwards of 1.6 million people are living without full indoor plumbing.

T

o neighbors, it looked like a "moonshine shack," a little yellow wooden hut, with overgrown weeds and no power or indoor plumbing, banged together by its owner, Robert Lewis Dear Jr.

And whenever Dear came to stay in his shack in the woods, the neighbors in Anderson Acres, a community of about seven houses along a steep, gravel road here, kept their kids inside.

"He was the kind of person you had to watch out for," said one neighbor, who asked not to be identified, saying he feared retaliation from Dear or his family. "He was a very weird individual. It's hard to explain, but he had a weird look in his eye most of the time."

Dear, 57, the man in custody for Friday's shooting at a Planned Parenthood clinic in Colorado Springs, appears to have been a malcontent who drifted from place to place in the past couple of years. In addition to the shack, he lived in a mobile home in another town in North Carolina and a camper on a piece of vacant land in Colorado, which he shared with a woman who moved with him from the East Coast.

Some who knew him found him unremarkable, while others said he seemed delusional and aggressive. He had a history of run-ins with neighbors and police, including arrests for cruelty to animals and being a "peeping Tom." He was not convicted in either case.

"It's just too devastating, it's just something you can't fathom happening," Pamela Ross, who was married to Dear nearly 20 years ago, said in a brief interview Saturday. She declined to comment further.

Dear's problems with the law date to 1997, when his then-wife reported to police that Dear had assaulted her, according to reports filed with the Sheriff's Office in Colleton County, S.C., where Dear lived at the time. She declined to file charges against him but told police she reported it because she "wanted something on record of this incident occurring."

Colleton County police released reports of at least seven other incidents where Dear had disputes or physical altercations with neighbors or other residents.

"He complained about everything," said the neighbor. "He said he worked with the government, and everybody was out to get him, and he knew the secrets of the U.S.A. He said, `Nobody touch me, because I've got enough information to put the whole U.S. of A in danger.' It was very crazy."

But there are two subjects that never came up:

The suspected gunman's neighbors in Black Mountain said Robert Lewis Dear kept mostly to himself. But James Russell said when Dear did talk, it was a rambling combination of a number of topics that didn't make sense together and he tended to avoid eye contact.

"If you talked to him, nothing with him was very cognitive," said Russell, who lives a few hundred feet down the mountain.

Two topics Russell said he never heard Dear talk about were religion or abortion.
