The sister's ex-boyfriend apparently engineered the whole thing. Custody battle gone bad:
2 men charged in deaths of 3 at Chicago-area home
(AP) – 2 days ago
DARIEN, Ill. — Two men have been charged in the shooting deaths of three family members at a suburban Chicago home.
The DuPage County State's Attorney's office says Johnny Borizov hired Jacob Nodarse to commit the killings. They face murder and conspiracy charges.
They're charged in the fatal shootings of 48-year-old Lori Kramer, 50-year-old Jeffrey Kramer and their 20-year-old son, Michael Kramer, at their Darien home.
The Kramers' 25-year-old daughter Angela hid in a closet during the shootings and was unharmed.
Prosecutors say Borizov is Angela's ex-boyfriend and that the two had been involved in a custody dispute over their 1-year-old son.
It wasn't immediately clear whether the men have attorneys. They're due to appear in bond court on Sunday.
