Lock drilled by the caretaker but not changed over day no one had been there and stolen laptop?

Info.

I was still there where my caretaker has drilled the lock. Then later started to go shopping. (4 hours) Come home laptop away so you could go in and out. What can you do in such a situation?

Do not drive away for 4 hours when the front door is open.

You went shopping 4 hours, even though you knew your door was open?

Since you can't do anything, is completely self-inflicted.
