As a result of the continued investigation into the death of a 19-year-old man east of Alice Springs on New Year's Day, two males, aged 17 and 22, who were arrested last week, have now been charged with murder.
A second 22-year-old was extradited from Melbourne on Monday and appeared in the Alice Springs Local Court for murder on Tuesday.
All matters remain before the court.
Northern Territory Police would like to thank the community for their continued assistance in this investigation. The video that police were calling for assistance to locate has now been located.
Detective Acting Superintendent Joe Carbone said "These arrests and subsequent charges have been the result of an incredibly large investigation spanning over two and half weeks with detectives, specialist investigators and forensic experts working around the clock, without rest, to bring closure to the family.
"A young man has tragically had his life callously taken from him and police remain committed to holding those responsible to account."
