The pedophile who shocked Germany and the whole world with his heinous act as he sexually abused 13 children just one month old while pretending to be a babysitter was sentenced to 14 years in prison.

Markus R., 45, drugged infants in their homes before sexually abusing them, according to the Cologne District Court.

The married computer expert has been filming himself abusing them and sharing the footage on sites accessed by pedophiles on the dark web for the past 14 years.

Investigators said it took 17 days to copy the data from his computer due to the sheer volume of gruesome videos and images.

Between 2005 and 2019, Marcus R., from Wermelskirchen, abused 13 children.

The prosecutor said he committed 124 sexual abuses of minors with the youngest child being a one-month-old baby girl.

Posing as a trusted babysitter, Marcus R. sexually abused the children while their parents went to work or out with friends.

Among those he abused were the two young sons of a policeman.

An indicative case of his heinous action is that of a family who hired him to take care of their children, who were then aged two and four, as for a long time the accused stayed with the children while they supervised him.

Marcus R. visited the family home every month while the parents were at work.

Only during these hours, he drugged the boys before sexually abusing them and torturing them with sex toys he had brought in his bag, Die Welt newspaper reports.

He filmed himself sexually abusing young boys and sent the videos to other pedophiles, while encouraging fathers to abuse their children, it says

Marcus R., who has described his behavior as “disgusting” during his trial, was arrested by police in December 2021 at his family home.
