NEW HAVEN — A 21-year-old man was arraigned Wednesday for a fourth homicide, the latest charge stemming from a 2007 killing he allegedly committed when he was 17.

Zackery Cody Franklin, shown in the photo in court, who is jailed on three other murder charges, said nothing in court when he was arraigned for the December 2007 slaying of Jeremiah Johnson, 32, whose body was found near the entrance of East Rock Park at the Hamden town line.

His alleged accomplice, John Torry Denby, 27, also is in jail in lieu of nearly $400,000 bail stemming from drug sale arrests.

Their public defender and court bond commissioner acknowledged that bond for both was “academic” given the fact that they have been unable to post the existing bonds.The bail commissioner noted that Franklin already was jailed in lieu of more than $5 million bail in the other cases.

Regardless of any new bond on top of that, it seemed impossible he would be able to post it. Franklin, of West Haven, has been charged with killing three people in two cities. Johnson was the fourth. He is accused of killing Ryan Barnaby in 2011 when the victim allegedly showed up to sell him a gun in Edgewood Park. Last July, he allegedly killed a man in Waterbury when, while celebrating his 21st birthday, he tried to rob him of his three-wheeled motorcycle.

That same month in New Haven, he allegedly killed John-Claude James in the Hill during a robbery involving a gold chain.

Franklin fled the state and was arrested in November in Virginia.

In court Wednesday, he stuck out his tongue to someone in the gallery and smiled.
