He is being held under $70,000 bond.Walker received the charges when lawmen arrived to arrest him on an outstanding warrant and noticed him throw away something.“I saw him throw down a sandwich bag of a white substance believed to be ammonium nitrate,” said sheriff’s deputy Joseph Vanbommel, noting the substance was wet and is commonly used in the production of meth.A search of his person revealed a cigarette container with 37 blue oval pills believed to be Alprazolam and an oxycodone was found in his pocket. A search of the house revealed even more evidence against him.“There was a suitcase and a laptop bag on the couch in the living room that the house owners said belonged to Johnny Walker,” Vanbommel said.
