He died on New Years.

A Wisconsin family is mourning their 11-year-old son who died on a Make-A-Wish trip to the Mall of America in Minnesota over New Year's.
Sixth-grader Mikey Choroszy of Sussex had brain cancer. Mikey experienced the FlyOver America ride, shopped at The LEGO Store and rode the Ferris wheel at the megamall in Bloomington, Minnesota. But the boy became unresponsive at dinner and died on New Year's Day at a Minneapolis hospital.
Mikey was diagnosed with a tumor on his brain stem about 15 months ago. His mother, Tammy Wildish, told WTMJ-TV her son "was a fighter, he never gave up."
As of Wednesday, a GoFundMe  page has raised more than $41,000 , more than twice its goal of $20,000.
