A Staten Island man accused of stabbing his parents to death is now in custody on Staten Island after being extradited from Tel Avivearly Sunday, police said, and will be arraigned Monday.

Eric Bellucci, the suspect in the grisly murder of his parents, was arrested inside Ben Gurion International Airport in Friday while attempting to purchase tickets to China.

Bellucci's parents, Arthur, 61, and Marian, 56, were found dead Wednesday night inside their home located at 3 Poillon Avenue in Annadale. Belluci's 25-year-old sister, Vanessa, made the horrifying discovery as she walked into the foyer of the home and found a series of blood stains.

When police arrived on the scene, they couldn't find Bellucci, who apparently lived with the couple. Instead, they found his car at Newark Liberty Airport around 1 a.m. Thursday and ultimately tracked him down in Israel.

Bellucci was apparently planning on staying with a friend in Tel Aviv, however a ground attendant at Ben Gurion Airport became suspicious of Bellucci when she observed unusual behavior. After his credit card was denied when he attempted to buy tickets to China, Bellucci apparently told the attendant he would return in time for an afternoon flight with an alternate source of money.

Friends suspect Bellucci may have killed his parents over a heated argument that occurred about a week ago. They and family members say that Bellucci is schizophrenic. They say he was not taking his medication for the mental condition, and that may have prompted the altercation he had with his parents.

Bellucci was once a star athlete at prestigious Stuyvesant High School, and his father was a senior associate at a large real estate company, according to published reports.
