Shock of brothers' deaths still lingers. John Ziska is trying to find ways to cope with the deaths of his sons JD and Brian Ziska, two former star quarterbacks at Arcadia High School, whose deaths in the past year have left many in their hometown of Arcadia reeling. This fall, the Arcadia High School football program has ceremonies planned to honor them. Last summer JD Ziska died of a stroke at age 35. Brian Ziska had a massive heart attack.
