Shawn Kavanagh, 23, was charged with two counts of first-degree murder, four counts of armed criminal action, first-degree assault, first-degree domestic assault and first-degree burglary.
Police said Kavanagh went to a house in the 26000 block of Humber Rd. to see his estranged wife, who had been staying at the home with several friends.

Two of the women were pronounced dead at the scene. The suspect's wife and the 8-year-old were taken to a hospital in critical condition.
Authorities also found an 18-month-old girl unharmed inside the home.
Kavanagh is being held in the Warren County Jail.
