Editing Jacobus van Nierop (section)

==Offending==
van Nierop, who used the name Mark, arrived in the rural town of Château-Chinon in 2008. As the area struggled to attract health professionals, locals were delighted and he set up a dental practice.

He became known as a hard worker and a friendly, approachable figure. He was also known locally for his flamboyant style, driving a large 4x4, keeping a big dog, and puffing on cigars.

However, van Nierop rapidly began performing painful and pointless work. He had twin motivations; fraudulently charging for the work against clients' insurance, and sadistic joy in causing pain and suffering. He would knock patients unconscious and pull out multiple teeth, often causing abscesses and even breaking jaws in the process.

Patients received multiple injections of anesthetic and were left bleeding heavily for days afterward. Some were worked on several times in quick succession over a period of a week.
