OMAHA, Neb. (AP) — An Omaha teen convicted of the gang-related killings of two others has been sentenced to 75 years in prison.

Charles Trotter was sentenced Friday.

A Douglas County jury found Trotter guilty in June of two counts of first-degree murder and other crimes in the shootings of 25-year-old Dexter Joseph and 26-year-old Marcel Lovejoy. Both men were found dead in a north-central Omaha apartment on Jan. 3, 2015.

Trotter was 16 at the time but was prosecuted as an adult.

Trotter’s first trial ended in a mistrial in March after a several fistfights broke out in a courtroom hallway during a lunch break. The brawl involved more than 30 friends and relatives of Trotter and his victims. Four of the people were arrested.
