Jennifer Hudson will never feel ''complete closure'' over the brutal murders of three of her family members.

The 31-year-old singer-and-actress - whose brother-in-law William Balfour received three life sentences last July for killing her mother Darnell Donerson, 57, her brother Jason Hudson, 29, and her seven-year-old nephew Julian King on October 24, 2008 - said her emotional wounds have not healed and they probably never will.
