Counselors are available at Glenbrook North for students struggling with Garrity's death. Counselors are also on-hand at , where District 225 summer classes are offered this year.
"The loss of a student is always going to influence the energy and feelings about school," Pryma said. "We will do our best to help with that transition when school begins in August."
