A Tongan man found guilty of shooting and killing of another Tongan man in the parking lot of a Maverik store in Salt Lake City was sentenced to 15 years in jail, a court ruled Friday 22.

Vilisoni Tuiono Angilau, 22, was sentenced by Judge Bernards-Goodman to serve three to 15 years in jail on the manslaughter count and one to 15 years on the firearm count. Goodman ordered the terms to run concurrently.

In April 13, 2013 Angilau and other members of the Tongan Crip Gang were looking for Sione Fakatoufifita,19, who was part of the rival Baby Regulator Gang, through the Glendale area before finding him at the store, shooting him multiple times, police reported.

Angilau’s defence attorney, Michael Langford, told the 3rd District Court judge his client was not in the right state of mind on the day of the shooting, having spent days drinking and smoking methamphetamine, LA Media report.

Angilau is the younger brother of Siale Angilau, who was shot dead by a U.S. marshal as he lunged at a witness in federal court in 2014.
