"The loss of a staff person is difficult, but to lose a family member on Christmas Day at the hands of someone in our custody is a tragedy beyond comprehension,” department Director Annette Chambers-Smith said in a statement posted on the department's Facebook page.

An investigation is underway into the death of an Ohio corrections officer. Officials say Officer Andrew Lansing was attacked by an inmate on Christmas morning at the Ross Correctional Institution, in Chillicothe. The prison says Lansing died as a result of the attack. Officials did not name the inmate involved, or say what led up to the attack.
