Police say Kustok shot his wife in their bedroom and tried to make it look like she had killed herself, then waited 90 minutes before wrapping her in a sheet and taking her to the emergency room.
Kustok told investigators his wife shot herself. He said he found her with her arms folded over her body, with her right hand holding the revolver.
The Kustok’s children, Sarah and Zak Kustok, appeared in court for the arraignment. They say they know their father could not have committed the murder and are standing behind him.
"Zak, Sarah and Nicole miss Jeannie terribly and love her a great deal. They are in contact with their father on an almost daily basis and have visited him at Kankakee. They intend to stand by their father throughout this process and will be with him until the end. They believe in him and they love him, as well," said their attorney, Peter Rush.
Sarah is a sports anchor and reporter for Comcast. Zak was a popular quarterback for Northwestern University.
Allan Kustock is being held on $2 million bond. He's scheduled to be back in court Dec. 14.
