(Cover) - EN Showbiz - The man accused of slaying Jennifer Hudson's family has been found guilty of the crime.

William Balfour went to trial for killing the Grammy-winning singer's mother Darnell Donaldson, brother Jason Hudson and seven-year-old nephew Julian King.

Three days after the defence rested on the case, jurors have delivered a guilty verdict on Balfour in a Chicago courtroom Friday.

When "guilty" was read aloud witnesses claim that many broke out in tears.

According to a Chicago Tribune reporter, Jennifer was in attendance, wearing a black and white shawl while her fianc David Otunga and her sister stood by for support.

Defence contended that William, who was married to Jennifer's sister Julia, went on a jealous shooting rampage after he thought she had started seeing someone else and didn't want to be with him anymore.

Jennifer's nephew Little Julian was found dead in an SUV three days after the bodies of Darnell and Jason were found in their Chicago home in 2008. (C) Cover Media
