Rose grew up in Lake County and friends say he frequently visited the Winthrop Harbor Skate Park, where the memorial was held.
"It gives me pride to see this turnout and to see everybody here like this. Anthony would have been proud of it," Michael Sperry, father, said.
Rose attended Zion-Benton Township High School before moving to Arizona when he was sixteen. Family members say he found his calling when he became a firefighter.
Police will escort Rose's body to a Zion funeral home, where services will be held on Thursday evening.
