CLEVELAND-- It affects just one in 5,000 babies, including 6-year-old CJ DeJohn.
Hypoplastic left heart syndrome is a rare congenital heart condition. Basically, patients have half a heart.
By the time CJ was six months old, he already had three open heart surgeries. But like any little boy, he enjoys superheroes, including the real-life ones of the Cleveland Division of Police.
On Thursday, Cleveland police, the FBI and A Special Wish Foundation will team up with FOX 8 News to make CJ's dream come true.
"When we asked him why he wanted to be a police officer, when he said, 'All I want to do is protect people,' it just melted us," said Jason Beudert, of A Special Wish.
The kindergartner will get to be police chief for a day.
"Something is going to happen where he is going to have to jump and save Cleveland, and particularly, Christmas here. It's going to be really exciting," Beudert said.
CJ needs your support. Come out and cheer him on as he becomes Cleveland's chief of police on Thursday. You can find him at Tower City at 11:15 a.m., Gateway Plaza at 2:15 p.m. and the Rock and Roll Hall of Fame Plaza at 3:15 p.m.
