Friends and family took to social media Tuesday night to express their memories and sorrow in the loss of Hughes.
Grief counselors were at Hillwood throughout the day Wednesday to work with students, staff and faculty to help deal with the tragedy.
Hillwood High School's executive principal, Dr. Steve Chauncey, said Hughes was a "very personable young man" with "potential to be a success both socially and academically."
He also said Hughes has an older brother who attends the high school and is on track to graduate next week. The senior did not attend school Wednesday, instead he was with family grieving for his younger brother.
