A very brave Jennifer Hudson has testified in the murder trial of William Ballfour the man accused of shooting her brother Jason Hudson, 29, her mother Darnell Donerson, 57, and her nephew Julian King, 7, in October 2008.

Balfour was married to Jennifer's sister, Julia. According to her testimony Jennifer told her 'over and over again not to marry him. We did not like the way he treated her.' Jennifer said that she had known the man since they were at school, but she never liked him.

Jennifer's sister Julia also testified, saying that Balfour had told her "If you leave me, you'll be the last to die. I'm going to kill your family first."

The trail continues. If convicted, Balfour could get life in prison.
