The younger teen in the Russian roulette shooting has been charged as a minor.
The injured 17-year-old is recovering at Jersey City Medical Center.

The new mayor says he is addressing the safety concerns and activities of his city's youth.
"We're expanding after-school programs, summer jobs - stuff we will do immediately," Jersey City Mayor-elect Steven Fulop said.
