A 16-year-old from Milford is in police custody in connection to a Saturday fight that left McGrath dead and three other teens injured, according to authorities.
McGrath lived in Shelton but attended Fairfield College Preparatory School, a nearby Catholic school, where he was a junior. His older sister, Rosie, is a senior at Shelton.
Before the game, their parents walked out to the center of Finn Stadium behind Shelton High School for a solemn ceremony.
Kevin McGrath, the teen’s father, addressed the crowd, which wore a sea of light blue instead of each team’s colors.
“Rosie and I appreciate everything this community has done.,” he said. “This is a day to celebrate Jimmy’s life.”
Maggie McGrath, the victim’s mother, held back tears on several occasions during her husband’s speech.
As the announcer introduced each team’s starting lineup, players on both teams approached the parents, gave them each hugs and then trotted back to the sidelines.
The game got off to a fiery start, with FP scoring 13 unanswered goals in the first half.
