George Toriello sent me this material on John B. Zisa on January 14, 2020 from Army websites and Find a Grave.  

There is a John Zisa listed on the Hackensack Wall Unit in the high school, which I am going to assume is the same person, but I could be wrong.  The name did not have a star on it, but it very well may have fallen off.  His name John B. Zisa is listed on the Plaque at City Hall in Hackensack, which honors those who have died in service.  There is no John Zisa or John B. Zisa listed on the 1946 Yearbook Dedication Page, only a Carmen Zisa. 

          John B. Zisa, according to military and census records was born on April 2, 1923 in New Jersey.  The 1930 Census shows the family was living in Lodi.  The 1940 Census shows his father Guglielmo (William), mother Carmela, and himself at the age of 17 had moved to 21 Worth Street South Hackensack.
 
Private John B. Zisa, while just crossing the Rhine River into Germany with the U.S. Army 17th Armored Infantry Battalion, 12th Armored Infantry Division known as, “The Hellcat Division” was Killed in Action March 31, 1945, only a little over a month away from the end of the war in Europe in early May 1945. 
John B. Zisa received the Purple Heart for his ultimate sacrifice only two days shy of his 22nd birthday. 
  
Apparently, John B. Zisa was repatriated and is buried in St. Joseph's Cemetery in Hackensack.
