A local businessman and a female companion were arrested Thursday on charges that they tried to hire someone to murder two people they know.Sources say the would-be victims are his ex-wife and her ex-husband. Gregory Christofakis, 50, owner of Greg\u2019s Auto Body on New Haven Avenue, and Ziba Guy, 44, were charged this week following a police investigation. They were arraigned in court Thursday, and are scheduled to be back in court Oct. 23.The Milford Police Department said Christofakis and Guy, both former Milford residents who now live in Orange, were arrested in connection with an alleged plan to solicit the murder and assault of two people.Local television media, including Channel 3 Eyewitness News, interviewed Guy\u2019s ex-husband outside the courthouse today, and reported that the pair wanted to hire someone to kill their respective ex-spouses.Investigators received information regarding the alleged plans, which led to arrest warrants being issued, according to Police Spokesman Jeff Nielsen. Christofakis is being charged with criminal attempt to commit murder and conspiracy to commit assault and is being held on a $750,000 bond.Guy is being charged with conspiracy to commit assault and is being held on a $250,000 bond.Just a year ago, Christofakis was an active member of the business community, hosting seminars at his New Haven Avenue business and showing up at local business events.In 2011, area media wrote an article about how Christofakis had come to the aid of a stranded motorist after being sent to tow her car from I-95. The motorist was distraught because she had a sick baby in the hospital, and Christofakis went to great lengths to make sure the woman got home, and even arranged for insurance to fix her car quickly.Last year Christofakis appealed to the local police department to be able to tow cars that the local police tag. He said at the time that the police regularly denied him inclusion on the tow list because he had a criminal past that stemmed from an altercation with a family member.One former customer who did not want to be named said Christofakis seemed exuberant and focused on his business last year but that something clearly happened: Suddenly he didn\u2019t seem focused on his job and lost a considerable amount of weight.The customer did not know details of the arrest. Details also were not available Thursday at the courthouse, where an arrest warrant affidavit usually provides details of the police investigation leading up to the arrest. A clerk at the Milford Superior Court said the arrest warrant file will remain sealed while the investigation continues.
