How to prove someone hit my car at the Astros game?

Yesterday I parked at the parking lot across from original Irma’s while attending the Astros game. I don’t usually park there so I took a picture of where I was and just so happened to take a picture of truck next to me. If you were the truck, to get out of the parking lot you had to pull out to the right to get to Commerce St.

In my mind, the damage seems pretty consistent with too big a truck in too small a lot, and cut the corner scraping up that front driver side of the car. You can easily see in picture 1 there is no damage when I parked.

I didn’t notice the damage until this morning. I can’t imagine there are cameras in the parking lots. What’s the best way to sort this out? Who should I contact?

Thanks!!
