Why did he do that to his wife.
Was she cheating?
Don't know, closest we get to an answer is -
"the spouses involved in this case have been separated for some time. He lived in the former joint apartment near Mendig in Rhineland-Palatinate, about 70 kilometers from Limburg, she with her two children in the Limburg women's shelter. The man with Tunisian ancestors was born and raised in Germany, the Tunisian woman was a teacher. The Youth Welfare Office in Limburg took their two children, a girl and a boy aged two and three, out of kindergarten and took them into foster care."
They are burying the story.
