Combs, whose case was sent from adult court to juvenile court in August, was found guilty last month by Family Court Judge Robert Rebstock of second-degree murder, robbery and conspiracy in Greaves' death.
He was also found guilty of robbery and conspiracy in a separate incident about an hour before Greaves was shot in which a 48-year-old woman was robbed on Rugby Street near Upsal in Stenton, about half a mile from Greaves' home.
Today, Rebstock ordered Combs to be committed for two years at the George Junior Republic facility in western Pennsylvania. He will be in the intensive-supervision unit there.
Combs, a thin boy shackled with his hands behind his back, said nothing during the hearing except when Rebstock asked if he had any questions. "No, they [his attorneys] explained everything," he said.
Public defender Stephen Gross noted in court that "at age 4, he [Combs] witnessed his father shooting his mother."
The mother, Shawn Combs, is alive and was at the hearing this morning with six other family members. She acknowledged after the hearing that her husband had shot her, but declined to say more. Family members said they were satisfied with the result of the case.
Gross declined to elaborate outside the courtroom about the shooting of the mother, or about anything he said in court.
Assistant District Attorney Chesley Lightsey said she was happy that Rebstock had found Combs guilty of second-degree murder. "He now has a second-degree-murder conviction" on his record, she said.
Spellman is awaiting trial in Greaves' murder in adult court. She also faces trial in the robbery of the 48-year-old woman in the earlier incident, in which she was believed to have conspired with Combs. Spellman and Combs lived near Cedarbrook.
The murder of Greaves shocked the neighborhood because Spellman was then just 17 and Combs 14, and because Greaves, who remained single all his life and had no children, was known as a quiet, friendly man who kept to himself and loved tending to his garden.
