With two crime scenes, a suspect in custody and an outraged community, Chicago's top cop said he is confident investigators will find clues to solve the deaths of Oscar winner Jennifer Hudson's mother, brother and nephew.

"I suspect we'll have some evidence that will link us to the killer," said Police Superintendent Jody Weis, adding that surveillance cameras throughout the city might have captured images that would help the investigation.

Id body

Hudson was among seven family members and close friends, who cried and held hands as they identified seven-year-old Julian King's body from a live image on a television screen at the Cook County Medical Examiner's office Monday afternoon.

The boy was found dead earlier Monday in the back of an SUV, ending a frantic search that began after the shooting deaths of Hudson's mother and brother three days earlier.

Chicago police spokeswoman Monique Bond said the child also had been shot. The medical examiner's office planned an autopsy yesterday.

Weis said a motive remained unclear. Police have characterised the slayings as "domestic related" and authorities have been questioning Julian's stepfather, who has been estranged from the boy's mother and is being held on a parole violation. No one has been charged in the slayings.

"It wasn't a case of a stranger-type homicide," Weis said.
