Grandson Chris Marcum was beaten into a coma

Hello our grandson Chris Marcum was walking his dog in downtown Reno when he was attacked, beaten, and dog stolen. He is still in a coma and on life support. Medical staff is saying that he will have permanent brain damage. His mother is having to drive from Carson City to Reno at least once a day, and trying to hold down a job while dealing with all of this. I'm trying to help with gas and other bills. Of course there are future costs of care coming up in the near future so any help would be greatly appreciated.
