Flikken Maastricht S13E04 - Jongens

On his way back from soccer practice, a boy is sexually abused and murdered. He has a sports sock in his throat, reminiscent of an earlier case in Drenthe. When it turns out that the victim's coach in Drenthe—who was also a suspect at the time—now lives in Maastricht, all the alarm bells go off. Marion and Romeo encounter an elderly woman who is desperately lashing out at people in a supermarket. Is she simply demented and unmanageable, or is there more to her behavior?
