Lost Drone (Superior)

My brother was flying his drone(inexpensive but still nice) at billings park Sunday and it fell on the other side of the bathroom building.
There was kids and mother and father in the playground area and as he was walking to get it and he heard one of the kids say I found it.
He couldn't find it any where and came back home I went with to help him look for it and after awhile of looking where it should be he tells me about the kid and what he said.
I told him you never said that so I'm pretty dang sure the kid found it and took it.
And that explains why they all left so fast when we got there to look.
I'm hoping the parents see this and if they have it to let me know,because its really useless without the controller.
