Weird news - Couple enslaved girl for 16 years

From time to time, we come across cases of people exhibiting extreme behavior towards other people. We saw this in the case of the terrorists belonging to the Islamic State, and we also see this in the case of dictators and people living in oppressed countries. However, even in developed countries, one can see people exhibiting similar behavior. It is even more surprising that this can happen inside the western countries, where there are institutions to find out and catch people who are doing illegal activities.
From time to time, there are stories that come out about people enslaving other people, and doing it is reprehensible, even more so when you do it to somebody who is a child and who does not know his or her rights. There are steep penalties including long jail terms and financial penalties as well when somebody is convicted of the same, but how do you compensate a child who has lost their childhood and has huge scars because of the mistreatment. In this case, the jury convicted the couple for the 16 years of enslavement that they did (link to article):

A federal jury on Thursday found a Texas couple guilty of enslaving a girl from Guinea for 16 years at their home in a Dallas-Fort Worth suburb, where she was forced to cook, clean and care for their children, investigators said. Federal authorities had accused the couple, Mohamed Toure and Denise Cros-Toure of Southlake, of forcing the girl to work for them and their five children from when she was 6 until she was 22, according to a court filing. Mr. Toure is the son of Guinea’s first president, Ahmed Sékou Touré, who led the country for 26 years until his death in 1984. After a four-day trial and a day of deliberations, the jury found the couple guilty on several counts, including the forced labor charge, which carries a maximum sentence of 20 years in prison. A sentencing date has not been set.
