Us is reporting that the “person of interest” in the shootings of Jennifer Hudson’s family had previously threatened to kill his ex-wife, Jennifer’s sister Julia Hudson, and to “mess up” her family.

Neighbors report that William “Flex” Balfour, currently in police custody, had been involved in a domestic dispute one month ago at Jennifer Hudson’s mother Darnell Donerson’s home in Chicago.

The dispute was reportedly over Julia Hudson’s claims that Balfour sold a car that he didn’t have permission to sell. Balfour fought with Jennifer Hudson’s brother Jason and her ex-fiance, James Peyton.

“Flex tried to start a fistfight with Jason, and James beat up Flex,” a source explains. Balfour reportedly then threatened the family saying “he would kill Julia and mess up everyone in the house,” the source adds.

This guy is a real Negative Nancy, and I’m sorry to use such language but I’m pretty upset. Since he killed three people I think we should find some way to kill him, then bring him back to life and kill him again and then once more. But you don’t tell him beforehand. It’s a surprise.

It’s been confirmed that the young body found yesterday morning is in fact 7-year-old Julian King. Jennifer Hudson positively identified the body of her nephew. Police sources say he was fatally shot multiple times.

The police held a press conference yesterday afternoon and really didn’t give any details. They continued to say that William Balfour is only a person of interest.

This is truly horrific and there really are no words. Beyond heartbreaking.

The body of a young boy was found inside a 1994 white Chevy Suburban on Chicago’s West Side this morning. The medical examiner has not yet confirmed if the child is Jennifer Hudson’s nephew, Julian King, but it’s pretty certain this it’s him.

The SUV was owned by Jennifer’s brother, Jason. Jason was murdered on Friday, the same day 7-year-old Julian was reported missing.

I had hoped it wouldn’t end this way. Sad and tragic in every way.
