Hi Brian,
So disheartening to hear of your loss and violation of your privacy.
I do have something that you may want to consider.
From the info you have placed on the thread: It smacks of kids entering and a simple opportunistic thief or thieves.
It often happens with school holidays. You may find them in the local neighbourhood. Possibly bragging to their friends.
It certainly is not a professional thief.
Here's hoping you get your toys back.
Cheers
