INDEPENDENCE -- Michelle Kehoe has been released from the hospital and transferred to Buchanan County to face charges of killing her 2-year-old son and injuring another son.

The Coralville woman was released from University Hospitals in Iowa City Saturday and was transported to the Buchanan County Courthouse in Independence, where she reportedly appeared in court for an initial hearing.

The hearing was held after business hours and was not open to the public.

A news release from Buchanan County officials said Kehoe, 35, is being held on $2.5 million bond in the Buchanan County Jail on charges of first-degree murder, attempted murder and child endangerment resulting in serious injury.

Kehoe is accused of covering her son's eyes with duct tape and cutting their necks with a knife. Her 2-year-old son Seth died, and her 7-year-old son Sean was injured.

Kehoe initially told authorities that an unidentified man attacked her family in a remote area near Littleton, but police later charged the mother with the crime.

Kehoe will be back in court Tuesday, Nov. 25. An attorney from the public defender's office in Waterloo will represent her.
