Who claims education expenses for non-dependent child?

My child is 24 and this is the first year that I *cannot* claim her as a Dependent.  She is in Graduate school full-time.  I paid for all her education expenses (tuition, fees, books, equipment, room & board).  The funding did not come from a 529 Plan.  Who should claim these education expenses as potential deductions -- myself or my child?  Thanks.
