This story's out of LA, but it sounds like it could have happened in any neighborhood. Honestly, how much do any of us really know about our neighbors? "On Hoover Street in Harbor Gateway, John Wesley Ewell was the guy neighbors turned to when they needed something fixed in their house. 'He's a real nice guy. The kind of guy who would give the shirt off his back,' said neighbor Sheila Spinks, who said Ewell recently fixed a light sensor for her. 'He didn't want money for it.' But L.A. County prosecutors charged 53-year-old Ewell with killing Roberts and three other people in a series of home robberies over the last month." "Ewell is described by sheriff's detectives as a career criminal who since the 1980s has been convicted of robbery, burglary and grand theft. He was charged in September, before the killings, with felony second-degree burglary from a Hawthorne Home Depot store. He had apparently lived on Hoover Street for five years." Man charged in four killings was known as kind, helpful neighbor - latimes.com Four bodies in a month, one may be an accident, but the others were all bound and gagged before being strangled. Did any of these people realize that they were living next door to a "career criminal?" And at 53, he doesn't look the role either. This reminds me of what Ferfal says about how and where professional criminals live: SURVIVING IN ARGENTINA: The professional Criminal We have available to us all the tools that we need, but we might have to pay a little for them and wade through mountains of data to see what kind of people are around. I haven't done it. Maybe it's worth the effort. If only one person in the "tight knit" community of Harbor Gateway had done so and then shared the information all around, these victims could have refused entry to a killer and made themselves less tempting targets.
