American Samoa's High Court has sentenced Talofa Seumanu to 20 years in prison for second-degree murder in connection with the death of 23-year-old Wyatt Bowles Jr, more than three years ago.
Seumanu was one of three people charged with the killing but he reached a pea agreement with the government.
He will be eligible for parole after serving one-third of that time, and he is also credited for time he has already served in jail, which is more than three years.
This means that Seumanu could be out on parole after serving three more years.
Another defendant, Richard Majhor, was sentenced to 40 years in jail without parole.
