Candles still flickered Wednesday morning at a city basketball court, evidence of the previous night’s vigil for a 2014 Westbrook High School graduate who died Tuesday after he was shot in Portland’s Old Port.

Portland police confirmed on Tuesday afternoon that Treyjon Arsenault, 19, who had been living in Scarborough, died following a shooting on Memorial Day in Portland’s Old Port area. Arsenault, a popular student at Westbrook High School, was captain of the school’s varsity football team.

Portland police said a second victim, a 20-year-old Portland man, remained hospitalized Tuesday afternoon but is “expected to make a full recovery.” Police did not release the identity of the second victim.

Police said in a report that Arsenault died early Tuesday morning in Maine Medical Center.

News of the shooting stunned Westbrook.

“The high school was shocked to hear the news of his passing,” said Westbrook High School Principal Jon Ross on Tuesday. “Our counselors set up a Crisis Team allowing students to process this sad news and receive the support they need. Our thoughts, prayers and hearts go out to Trey’s family.”

Arsenault was a “very popular student” at the school, he said.

By Wednesday, Ross said, the school was still reeling from the news, but that it was a little quieter than Tuesday. He said counselors talked with students, and football coach Jeff Guerrette, who coached Arsenault, hosted about 40 students during the day to talk about Arsenault.

“I saw every emotion between 15- and 19-year-olds, from unsure how to respond to sobbing,” Ross said.

Ross said Arsenault was a “memorable kid,” adding that he was “funny and good-spirited.” He said he nicknamed him “Guns” because he worked out in the gym so often.

Mourners gathered Tuesday for a vigil at the basketball court near the Cornelia Warren pool in Westbrook, and some attending the vigil reportedly had guns.

“A couple practiced open carry,” Westbrook Police Chief Janine Roberts confirmed Wednesday.

But the vigil was peaceful.

“The event went off without conflict,” Roberts said.

Roberts had not been contacted by Portland Police Department about the shooting incident.

At the scene of the vigil, someone scrawled “R.I.P. I love” on the red painted area at the court’s sideline. A skateboard flipped upside down, a basketball, a floral bouquet, and a cross were among items left with several candles still burning Wednesday morning.

Ross said a fellow class of 2014 graduate organized the vigil spontaneously.

Noah Fredette on Wednesday re-visited the court where he had played basketball with Arsenault. Fredette said about 100 attended the vigil.

“He was a really good kid,” Fredette said.

Two of Arsenault’s close friends from Westbrook, Noah Collins and Kyle Heath, sent messages to the American Journal Wednesday about Arsenault. Collins and Heath also graduated from Westbrook High School last year, and had played multiple sports with Arsenault.

“Trey was a good kid. He was always goofy to hang out with and he always had a smile on his face,” Heath said.

Collins said he befriended Arsenault when he first moved to Westbrook in sixth grade, and since then, the two had a lasting friendship, often involving sports.

“We couldn’t stop joking around, and we couldn’t stop competing against each other in everything we did, and that never ended,” he said. “It was great to have such a good friendship that early in life, and he definitely brightened my days, just as he did everyone he ever met.”

More recently, Collins said, he and Arsenault lined up next to each other at the linebacker position for varsity football during their junior and senior seasons.

“We became so close we didn’t really need to speak to understand what either of us were thinking,” he said. “I have no doubt that had I ever needed anything, I could call Trey and he’d be there for me in a second.”

Heath said that ever since Arsenault moved to Westbrook, they played hockey, baseball and football together. Both Collins and Heath said they would constantly compete with one another off the field.

“Both of us pushed one another beyond our limitations and that’s what I think of most when I think of Trey,” Heath said. “It would be nice to have one more workout with him.”

Westbrook School Committee member Suzanne Joyce said Wednesday that her son, Collin, was also good friends with Arsenault. While her son is attending Maine Maritime Academy, she said, Arsenault and other friends were at her house during April vacation. She said her son was “devastated” by the news.

“He was just an incredible, polite kid,” she said about Arsenault.

She said she became very good friends with Arsenault’s mother, Nancy, through watching their kids play baseball and other sports.

Joyce said Arsenault had been attending college in Florida, but had since moved back to be closer to his family. She said he was currently deciding which local college to go to.

“He had incredible devotion to his family, very tight-knit,” she said.

On Facebook Tuesday, Arsenault’s father, Turhan Walker, posted a message stating, “Today is the coldest/darkest day in my life. I love you Trey Arsenault! Live in the sky my son.”

Police responded at 11:56 p.m. on Monday to 371 Fore St., at Da Block Studios, following a report of gunshots. Officers discovered that the two had sustained gunshot wounds and both victims were immediately transported to a local hospital.

Unknown suspects were last seen fleeing up Market Street toward Milk Street, according to police. Detectives and officers are interviewing witnesses and the investigation is ongoing. Initial investigation suggests there may have been more than one attacker, police said. No motive for the shooting has been established.

Mark Belserene, administrator for the Maine Medical Examiner’s Office in Augusta, said Tuesday afternoon that the autopsy has been completed. Belserene said the cause of death was from a gunshot and has been ruled a homicide.

Acting Portland Police Chief Vern Malloch Wednesday declined to disclose any information about how many times Arsenault was shot or type of gun.

Arsenault was known for his athletic ability. According to www.hudl.com, Arsenault was 5 feet 7 inches and weighed 175 pounds and could bench press 225 pounds.

“He touched everyone he ever met, and that is why there is such a frenzy over his passing,” Collins said Wednesday. “The community of Westbrook would never have been the same without him.”

Collins said that while he hadn’t spoken to Arsenault much over the last year, he knew Arsenault had an interest in rap music, saying he occasionally recorded his own music. Prior to the incident, Collins said, he hadn’t heard about him hanging out at the studio?,? and believes Arsenault was “just in the wrong place at the wrong time.”
