This gruesome footage shows two sisters slumped on the ground in a pool of their own blood after drug dealers tied their hands behind their backs and shot them in the head.

Andreza and Fabiola de Souza do Nascimento were snatched from Iranduba, northern Brazil, where they lived, on 23rd November.

They were allegedly tortured before being thrown from a car in neighbouring Manaus.

As they begged for their lives with their hands tied behind their backs, they were sprayed with bullets in their heads by three men, local media reported.

Paramedics pronounced Fabiola dead at the scene but noticed Andreza was still breathing.

They rushed her to Dr Joao Lucio Pereira Machado Hospital and Emergency Room, but she died of her injuries.

According to preliminary reports, the young women were killed over a missing payment to drug dealers.

The sisters were already known to police after they and three others were arrested in Iranduba in February for illegally carrying a firearm and drug trafficking, local media reported.

They are said to leave behind young children.

Their relatives – said to be unaware the sisters were involved in crime – are reported to be in shock.

Police are investigating the case.
