(E!) – Wasting no time, Jennifer immediately spoke of how she warned her sister not to marry William.

“I told her over and over again to not marry him,” Hudson said, voice trembling, on the stand. “We did not like how he treated her.”

Hudson, who appeared dressed-down for her testimony, wearing little makeup, with her hair pulled back and donning a black suit, also appeared to be crying when she told the court she “talked to her [mother] every single day.”

In the courtroom providing moral support for Hudson are her fiancé David Otuga and other members of the Hudson family.

Balfour is charged with first-degree murder in the death of 57-year-old Darnell Donerson, 29-year-old Jason Hudson and 7-year-old Julian King, in addition to home invasion, aggravated kidnapping, residential burglary and possession of a stolen motor vehicle. He has pleaded not guilty to all charges.

The trial is expected to last roughly four weeks.
