On Monday, jury selection began in the trial of William Balfour, the man accused of murdering Darnell Donerson, Jason Hudson and 7-year-old Julian King. The Grammy winning singer, who is on the witness list, is expected to attend regularly starting April 23.

Balfour, who was the estranged husband of Hudson's sister Julia, is accused of fatally shooting Hudson's mother and brother inside their Chicago home in 2008, while the body of Hudson's nephew was discovered three days later in an abandoned vehicle.

Balfour, who was also Julian's stepfather, has denied the charges and pleaded not guilty. If convicted, he could face a maximum life sentence.
