We enter this story in media res, with the Daily Mail reporting that a fourth man—22-year-old Logan Roepke (second image)—has been arrested in the ongoing saga of Nebraska's worst mother, a woman accused of pimping her two daughters. The sisters are 14 and 7 years old.

Authorities in Nebraska allege that the 35-year-old mother profited from at least seven men having relations with her 14-year-old daughter at least 20 times. They report that at least three men had sex with the other, younger daughter.

So far only four of the johns—Roepke, Shad Chandler (third image), Donald Grafe (fourth image), Alexander Rahe (fifth image)—have been arrested. Their ugly mugs are visible above.

"This is a very disturbing case," said patrol Superintendent David Sankey, in what might be the understatement of the year.
