UTICA, N.Y. (WKTV) - The alleged mastermind behind the jewelry store robbery that resulted in the death of New Hartford Police Officer Joseph Corr in 2006 has finally been arraigned on murder charges.

Marion Pegese, 36, of Philadelphia was in Oneida County Court Monday morning. Judge Michael Dwyer entered a not guilty plea for him, because Pegese said he wants time to hire an attorney.

Pegese was extradited from the New Jersey state prison system, and arrived at the Oneida County Jail on Friday. In February, he was sentenced in New Jersey to 18 years in state prison there for his role in a bank robbery in Freehold, New Jersey.

Here in Oneida County, Pegese faces one count of second degree murder, twelve counts of robbery in the first degree and six counts of robbery in the second degree.

Prosecutors say Pegese was one of four men who robbed the Lennon's W.B. Wilcox Jewelers on Commercial Drive on February 27, 2006. Two of the four men took police officers on a chase. Officer Corr was shot by one of them behind the Byrne Dairy in Kirkland. One of those two men, Toussaint Davis was immediately taken into custody and was sentenced in Oneida County Court to 300 years in state prison.

The second man, the man prosecutors believe shot Officer Corr got away but was tracked down and shot the next day during a shootout with police near Philadelphia, Pennsylvania.

Prosecutors say Marion Pegese and the fourth man Robert Ward, were in a separate car, and later tracked down in their hometown of Philadelphia. Ward was also sentenced recently for his role in the Freehold robbery along with Pegese. However, Oneida County Prosecutors say Ward has still not been entered in the State Prison System in New Jersey, so there is no time table of when he will be extradited to face charges here. But when he is brought back, prosecutors say they will hold one trial for both men.

Pegese whom prosecutors called the mastermind behind the Lennon's robbery and the Freehold robbery is due back in court on Friday to let the judge know whether he has indeed hired an attorney. If he hasn't, Judge Michael Dwyer will appoint a public defender.
