People have begun to post their crimes live even on Facebook. A Syrian filmed himself live on Facebook just minutes after killing his wife. Abu Marwan, who lives in Germany, is said to have stabbed his 37 - year - old wife four or five times before leaving with one of his children.

In the shocking video, he is seen with his face covered with blood and a cut in his hand while talking on camera. Behind him lies a little boy thought to be his son, who starts shouting during the film.

The 41-year-old was arrested by police after he fled the crime scene in Mehler on Friday, the Daily Mail reports. In the video he tries to justify the murder by saying he was sending a message to all the women who irritate their husbands.

That's how you end up, he warns.

He asks viewers to distribute the video. The man reportedly had gone to see his mate. The 41-year-old had wanted to solve things, but the woman, who had the custody of their three children, refused.

According to the German press, he had called the victim to ask for money. Their little girl was also reported to be at home during the shocking murder and called the police.
