William Balfour – the man considered a suspect in the shooting deaths
of Jennifer Hudson
's mother, brother and nephew – could have been spending the past few months in jail.
The 27-year-old parolee – who served seven years for attempted murder and vehicular hijacking – was busted June 19, when cops reportedly discovered crack cocaine on the driver's seat of his car, the Associated Press reports.
But despite his arrest, the corrections department declined to revoke his parole, allowing him to remain on the streets.
The charges were eventually dropped. But, the wire service notes, a felony arrest alone can often be sufficient reason to return a parolee to prison.
According to the AP, Balfour also missed a meeting with his parole agent on Oct. 24 – the day of the murders. (Documents reportedly show that he later explained his absence, saying he was "babysitting.")
Balfour – the estranged husband of Hudson's sister Julia – is now in custody on a parole violation, this time for possessing a weapon and failing to get treatment for anger management or substance abuse issues.
No one has been charged in the deaths of Hudson's mother, 57-year-old Darnell Donerson, brother, 29-year-old Jason Hudson, or her 7-year-old nephew, Julian King.
The boy's mother, Julia Hudson, took to her MySpage page Tuesday to vent her grief on the tragedy.
"Because I chose ... to love someone, it cost me my beautiful family," she wrote.
As for her son, Julian, whose body was discovered Monday (and whose death has been ruled a homicide
), Julia says his "soul is at ease." She concluded, "I take comfort in knowing that Julian is with my mother and my brother and most of all the lord ... Now he's my angel."
