Medical expenses for my son Brandon

On Saturday July 4th 2015 my son Brandon and his wife and several friends were on Main St. in Whitewater watching our fireworks when someone started shooting BB guns at the crowd. The window where my son was sitting by was shattered. They ran when the glass shattered but then my son decided to go back and wait for the police where the window shattered. While waiting for the police to arrive he felt something hit him in the eye. He went next door asking someone to call rescue for him because he couldn't see out of his eye as something was in it. He was transported to the trauma center where they discovered a BB in his eye. They needed to transport him to The UW-Madison to see a specialist.

My son has no insurance to cover the amulance bills, meds he needs to take and possible surgeries he will need to get his sight back in his eye. He is 75% blind in his eye right now and until swelling goes down they can not see what they need to do for surgeries.
He will be making many trips to Madison for treatment, surgeries, medication, etc. etc.
I am asking for help for him to help pay the bills that will be piling in. He is stressed and worried about all the bills now. 
If you can help it would be greatly appreciated as this is an incident he never planned on. 
One suspect is in custody and they are looking for more suspects at this time but in the mean time my son is accumulating medical bills.
Thank you in advance for any help you can give him.
