A state employee with knowledge of the investigation told The Associated Press on Thursday that Jean Henry is accused of showing Adam Lanza's body to her husband on Dec. 16, two days after the shooting. The employee spoke on the condition of anonymity because the inquiry is under way.
Messages were left with Henry.
Gov. Dannel P. Malloy says he would be "deeply disappointed" if the allegation is true.
A University of Connecticut Health Center spokesman confirmed Henry was put on administrative leave Dec. 21. The center handles personnel matters for the medical examiner's lab.
The investigation was first reported by The Hartford Courant.
