This video shows two teenage twin sisters dancing together and having fun before a second video was published showing them being made to kneel before being shot in the head at point-blank range.

Cops arrested a 17-year-old man in the Brazilian municipality of Pacajus on Wednesday, 14th July. He is suspected of firing the fatal gunshots hours earlier.

The police revealed he is already facing seven criminal charges including theft, illegal possession of firearms and grievous bodily harm before the latest crime is added to the list.

The police believe he is the same man who appears in the video shooting the two kneeling 18-year-old twin sisters in the head on a dirt road in Pacajus in the early hours of the same day.

The teen man, whose name was not divulged, was wearing the same clothes in which he appears in the video when the police arrested him.

The two victims have been named as Amanda and Amalia. They were each shot four times in the head.

Both teen women leave behind a child, Amanda a three-year-old daughter and Amalia a six-month-old son.

According to reports, the two sisters had been spending time and become romantically involved with suspected drug dealers, and they may have been killed because they “knew too much”.

Some reports say that the teens were taken to the deserted area where they were tried, convicted and sentenced to death in a kangaroo court before being summarily executed.

The police are investigating the case and officers are currently searching for other suspects involved.
