The nation is expected to turn a page today as Maryland pre-school teacher becomes the last Boston Marathon bombing patient to be released from the hospital. 

Erika Brannock will be released today and go through rehabilitation in Baltimore after having part of her left leg amputated.  She and her sister were among more than 260 people injured in April when two bombs went off near the marathon's finish line.  Three people died in the explosions.

The sisters were waiting for their mother to cross the finish line when the pressure cooker bombs went off.
