The convicted felon suspected of killing actresssinger Jennifer Hudson's mother, brother and nephew has told the police he is innocent but refuses to take a lie detector test.

William Balfour, the 27-year-old stepfather of Hudson's nephew and estranged husband of her sister, told detectives he had a good relationship with the Hudson family.

Balfour has been at the centre of the investigation since the bodies of Hudson's mother, 57-year-old Darnell Donerson, and brother, 29-year-old Jason Hudson, were found last Friday in their home on Chicago's South Side. The body of Balfour's stepson, 7-year-old Julian King, was discovered on Monday in an SUV on the city's West Side.

All three had been shot.

Balfour had not been charged by Wednesday and investigators are still gathering evidence

Balfour's mother, Michele Balfour, has said Hudson's mother kicked Balfour out of the family home last winter. She denied her son had anything to do with the killings. - Sapa-AP
