The mother of Towson native and Rollins College (Fla.) lacrosse captain Will Hauver said her son died of complications from the flu.
Lyndall Hauver said her son, 22, began feeling ill Sunday and was found unresponsive a day later.
She said her family has spent time at the Winter Park, Fla., school since his death, and has been touched by the campus' support.
"The school has been supportive beyond belief, and the lacrosse team also, as well as his many other friends outside of the lacrosse program," Lyndall Hauver said.
She said as many as 500 people were at a memorial service at the school's chapel Tuesday night, which ended with a candlelight vigil. On Monday, after news of his passing spread around campus, students and teammates gathered at the school's lacrosse field to reminisce and be together.
The Rollins lacrosse team will play its season-opener against Young Harris (Ga.) on Thursday and then attend a memorial service scheduled for 2 p.m. Saturday at McDonogh School in Owings Mills, his alma mater.
Will Hauver, who studied communication and fine arts, planned to enter the public relations or graphic design field after graduation this May. He featured his artwork on his own website, WLHart.org, and extended himself far outside of the lacrosse world at the school of 2,366 undergraduates.
"Here, he was called a hero. He was called a best friend, a leader," his mother said. "We heard quite a lot of people say, 'I was going to leave [Rollins], but Will extended himself to me and made me love it here again, because Will reached out to me constantly and let me into his world.'"
Will Hauver was also a founding member of McDonogh's squash team, along with friends he had already played tennis with. His mother, who survives him along with his father, Bob, sister Megan, and brother, Tommy, remembered him as "the kindest child, the kindest person."
"[He was] the most steady and big-picture," she said. "He was not one to whine and complain and carry on. He didn't understand why other people had anything to complain about. He welcomed and loved everybody."
