Newton is one of three men charged in the killing of Vladimir Voinov, 21.
Voinov was found in an apartment on Poplar Street. He did not live there and police said Voinov was selling marijuana when he was killed. His prospective buyers tried to rob him, police said.
Akeem Gayle, of New Haven, and Anthony Johnson, of Hamden, told investigators Newton was the gunman.
He faces felony murder and robbery charges. U.S. marshals captured Newton in Fort Myers three weeks ago. Marshals in Florida had been searching for Newton since police in Connecticut told them he might be staying with family there.
Voinov served on the UConn student Senate and as Sergeant-at-Arms. He once ran for student body president. And was the editor-in-chief of a campus weekly newspaper called, “Impolitically Correct.”
He grew up in New Haven and had been living in Hamden.
