Grosso, 22, was a native of South Florida.
Grosso was on two Ivy League championship teams at Penn, and played in all 30 of his team's games over his final three seasons. He had intended to enroll at the University of Miami Law school in the fall. According to The Miami Herald, he had been added Miami's roster the day before his death.
