After a two-day manhunt, police on Thursday arrested a suspect in a shooting on the crowded Naples Causeway during a Fourth of July celebration.

Alexzander Goodwin, 18, of Bridgton, was arrested at about 2:30 p.m. Thursday on Park Avenue in Portland, according to a statement from the Cumberland County Sheriff’s Office. He has been charged with reckless conduct and elevated aggravated assault, a Class A crime that carries a maximum sentence of 30 years in prison.

The sheriff’s office didn’t respond to a request for details about Goodwin’s apprehension. He was being held at the Cumberland County Jail.

Police have not identified the victim, whom they described as a juvenile male. He suffered non-life-threatening injuries and was taken to Bridgton Hospital and then to Maine Medical Center in Portland by LifeFlight helicopter, police said Tuesday.

According to Sam Luebbert, 26, who witnessed the shooting Tuesday evening, Goodwin and the victim had been fighting behind Rick’s Cafe when they were asked to leave by security. When the pair reached the causeway in front of the restaurant, Luebbert said he saw the shooter pull a handgun out of his backpack and fire about five times, striking the victim. As Luebbert ran to provide first aid, the shooter ran off.

The shooting was one of several incidents of gun violence across the country that took place at Fourth of July celebrations this weekend. Shootings in Washington, D.C., Louisiana, Florida, Philadelphia, Texas and Baltimore killed more than a dozen and wounded almost 60 people, The Associated Press reported.
