Click the link to see how to describe a person. I'm not sure what you're having trouble with, though -- are you wanting to learn how to describe, or have you forgotten how to enter a mall? Surely you've gone into a mall at some time in your life -- write what that was like.
Colloquially you can use either, but if you were to say 'in the mall' you would likely be referring to an object. There's a bookstore in the mall. If you said 'at the mall', you would presumably be referring to a person. Where is John? He's at the mall with his girlfriend. Of course, 'mall' can mean the physical building complex, in which case anything can be 'in' the mall, but 'at the mall would almost always refer to a person.
I would guess call for back-up and an ambulance. The Mall manager would be called, and other security staff alerted in case the " injured " person is a ruse to distract from some other activity.

The local mall would be a good suggestion. There are multiple stores to get everything for that special person. Something for them to enjoy with their partner.
