Tenant accusing of lost items during room showing

[Carlos Lez]

Dear fellow members, I am confronted with a weird accusation that I haven’t seen in 15 years of managing student rentals. We have multiple properties rented to students living in different rooms. We start showing rooms to prospective tenants right around a month before lease expiration. We have a blurb in the lease that has the tenant agree that with a 24 hour notice we will be showing their room. We barely spend a minute in a room to show the layout to prospective students.
subsequent to a showing yesterday I get the following email. I am seeking advice on how to  address this and help me with a response. We don’t require but advise tenants to carry renters insurance which they usually don’t carry. We don’t know what transpired and if any of this is even true. The email;

when I returned to my room this morning I noticed that my room looked out of place. I know you guys had people come look at the rooms Saturday afternoon between 3 & 5. My suitcase was opened when I returned and I had a bag that was ripped in it. I know some of my drawers were left a little open and my heels were out of place when I returned. I took photos of how my room looked before I left with timestamps and took photos of how it looked when I returned with timestamps. I am concerned because I had money in my wallet that was left in my room that is now missing. I think that if you are showing people the rooms this is an invasion of privacy of someone to go through my things. And I expect the money to be returned to me.
