House ransacked during closing!!

I am curious if there's any legal route we can pursue or if we are just SOL? We closed on a house on 12/30/24. We agreed to buy the house "as-is" meaning everything inside of the house is staying. The previous owner had dementia and his kids basically just packed a suitcase for him and left everything. The only items of value was maybe some tools & lawn mowers - everything else was cheap and would need to be donated or go to the dump. We agreed to take it as is because the tools we could sell to offset the cost & headache of having to clean out the entire house and the expense of the dump. We go there, and the house is ransacked. All the "nicer" items are GONE. We call the realtor, he says he gave permission to the neighbor to go into the house to grab some more of his personal items to mail to him (totally fine with us), however they took anything and everything that THEY wanted. We went to the neighbors house and at first the denied it, then they admitted to it. They took an office chair, multiple ladders, multiple tools, a patio set, all the nicer linens, a dish set, and who knows what else! They also absolutely BUTCHERED a tree out front and dragged all the branches into the driveway. The tree was super overgrown and they only cut one side of it - my best gue ss is because they wanted to be able to see through the living room window from theirs (they are directly across the street). What can we do?
