Premises accident claims can be tricky, but regardless your son should certainly consult with an experienced personal injury claim in your area immediately. Do not delay, as the attorney will want to do some investigation, and try to preserve any security camera video, if any, or other evidence that may show the condition of the grounds at the time of the fall. And, believe me, there are very few false slip and fall claims out there, but the insurance industry has done a good job of convincing ordinary citizens of this myth so they can get biased jurors in their cases. Good luck, and don't delay any further!
I would recommend that your son hire an experienced personal injury attorney in your area to pursue this matter. You can locate an attorney on avvo.com. Your son should speak with an attorney before signing anything or giving a statement to the insurer. Good luck to you and your son.
Definately consult a personal injury trial attorney in your county. The store should be responsible if there was a dangerous condition (the wood) on its property that it knew or should have known about or placed there without warning to patrons. Your son may also e assessed someportion of fault for failing to look where he was going. The store's insurance policy may not have a medical pay provision to cover medical bills but should have liability coverage for injuries arising out of their negligence
