24 year old birthday girl, shot dead outside her party house

Disturbing surveillance video released Sunday shows the moment a girl in the midst of celebrating in her 24th birthday is fatally shot by members of a gang outside her own house party in Brazil.

Eliana Ferreira Campos, dubbed on her Facebook profile as 'Miss Barbye Marley,' was the first victim of the triple homicide that took place in the municipality of Ji-Paraná around 11pm on Saturday.

Campos had rented out the party house she is seen on surveillance standing outside of while taking a smoke break and chatting with pals.

Not long after, Campos is approached by a group of people who begin physically assaulting her before one takes a gun and shoots her dead.

The two other victims shot dead afterward were identified by local police as Paloma de Oliveira Guimarães, 26 and Edmundo Cristian Ferreira de Matos, 18.

It's currently unclear how the trio knew one another.

Social media photos suggest the second two victims, Guimarães and de Matos, may have been romantically involved.
