sorry to hear this but sometimes the person maybe a bounty hunter or so and so if you google the wallet address you may find it in a spreadsheet with his/her details if lucky.Make sure to get a hardware wallet as the amount involved in getting a hardware wallet is very small compared to what you may lose to a hack should that be the case.
I already did a "research" but cant find anything except the transaction what took place. Well, that lucky guy might be laughing now...but for how long?
