A Portland man was sentenced Monday to at least five years in prison for his role in a shooting last Fourth of July in Naples that injured a Westbrook High School student and scattered a crowd gathered to watch fireworks.

Alexzander Goodwin, 19, pleaded guilty in Cumberland County Unified Court to elevated aggravated assault with a dangerous weapon and trafficking a scheduled drug, according to a statement from the Cumberland County Sheriff’s Office.

Goodwin received an 18-year sentence, with all but five years suspended, on the assault charge and a consecutive five-year suspended sentence on the drug charge, the statement said.

Currently held at the Cumberland County Jail, he will be under supervised probation upon his release.

The statement didn’t name the drug he was charged with trafficking.

The shooting occurred as more than 1,000 people waited to watch fireworks from the Naples Causeway, a scenic road and bridge that run between Long Lake and Brandy Pond. It took police two days to track down and arrest Goodwin, who they believe shot 16-year-old Tyler Fusco after the two got into a fistfight.

Goodwin initially faced additional charges, including attempted murder, and a maximum potential sentence of more than 80 years in prison.

During the investigation, deputies discovered an abandoned gun and bag near the Causeway Dairy Bar, located in the same direction witnesses said the shooter had fled. Inside the bag was a bottle of prescription medication bearing Goodwin’s name, according to police reports.

Fusco received non-life-threatening injuries to a shoulder and a leg, police said.
