I wasn't surprised at all that this happened. Some people have no shame. There have been instances of burglaries at the homes of a person who died during their funeral. Unfortunately we live in a world where if there is a publically posted event like a wedding (this would apply more to the parents of the bride/groom) or funeral (this could apply to the home of the deceased, and immediate family members, especially adult children of the deceased), where everyone knows your house will be empty, someone can easily find on the internet where you live, and know your home will be empty.
When my children get married and/or when my parents pass on, I'll find someone I trust to just hang out in my home while we are gone. Again, sad that you have to think about it, but you do.
