Help! Son's fishing gear stolen

We were fishing/camping at Battleground State Park in Clark County. My son was out fishing at the lake without an adult at 6am to catch that morning bite. Two Men on a blue Ford Explorer pulled up and took his yellow eagle claw pole with a shimano reel, and a very full black adidas back pack with 7 fishing cases of lures and tackle worth easily $500-$800 hundred dollars. This seems rediculous for a young man to have so much fishing gear, but this has been a cumilation of all of his Christmas, birthday, odd jobs tackle and gifts for at least the past 7 years.
My son is beyond devastated and is completely at a loss, he is autistic and bass fishing is the only he loves and spends all his time doing. For him, this is like losing your home. Everyone of those $10.00-$15.00 lures have a special memory, although they are irreplaceable, I'm hoping with our fishing community understanding the loss not only of the gear but also his faith in humanity.  We are a single parent family we cannot just replace years of gear.  If we could raise some, this would stay with him always to balance out the bad that has happened to him. Thank you all, for helping him make new memories and fish on.
