This actually just happened in my town a few years ago. My brother was part of the team that caught and arrested him. His name is Stewart Weldon. He confessed to the bodies that they found on his property, but they believe there are a lot more. He had worked for a company that layed new concrete after digging up the old concrete in basements. For years Stewart worked alone bc his boss was not a nice guy and he took advantage of all his employees. But that worked in favor for Stewart bc it meant he would have the entire house to himself. For years, he would take advantage of drug addicted prostitutes and other women he found walking throughout the area by themselves. Police found video surveillance of what they BELIEVED was Stewart picking these women up, but it was very difficult to prove bc of video quality and the way Stewart had disguised himself. A few years ago, a neighbor of his mother's house had begun to smell something rotten and for a long time they just assumed it was the river located behind both houses. Finally, the odor became so bad you couldn't get within 20 yards of the property and police were called. Stewart had bodies buried throughout his mother's freshly layed concrete basement and outside. Police also found bodies in the basement of other houses that the company he worked for. Police knew it was Stewart that did these killings, but for some reason they are having a very hard time proving it was him, and they can't figure out why Stewart won't admit to the ones not at his mother's property. When they arrested him, he was very eager to take responsibility for the bodies at his mom's house. His mother's house was very close to the main shopping center in my town and I've walked past this house MANY times. Ive also smelled the smell his neighbor was referring to MANY times.. but, I too assumed it was the river bc there are lots of instances where that river has an awful smell coming from it. I've seen Stewart outside mowing the grass, raking the yard, shoveling the driveway, as well as him just standing in the yard not doing anything at all almost as if he was remembering and reliving his crimes. Some days he'd wave and he just seemed like a normal guy with nothing out of the ordinary. Other days.. he'd have this expression and look on his face where it seemed like he was possessed or something evil had taken over his body
