Mysterious package floats from the sky and into the river.😲

I was over the river last night and noticed something drifting in the sky. So naturally, I started videoing. As it got closer it looked like a package under a parachute or balloon. It was pretty good size because I was quite a distance from it and had my camera zoomed in all the way. I called our local water patrol and they were nowhere in the area. By then, I had zoomed in on the video and could tell it was not a human moving on the river. With my necked eye all by all I could see was movement. He said, since it did not look like a human being that they weren’t gonna worry about it. If I had had a boat, I would’ve gone out to check and see what it was, but I did not have one accessible at that moment. I stayed about 2 hrs. and no one ever came to retrieve their package. I’ll always wonder just what was in that package.
