Milwaukee County Transit System bus operator Karen Martinez-Casper was driving her usual route on an early October morning when she noticed something disturbing.

The grandmother of two took action immediately.
What happened next, as she explained in our interview, will warm your heart.
Watch the video of her heroic actions and her recent recognition by the Milwaukee Bucks below.
