A man accused of trying to burn down his father’s house while his father was still inside has been sentenced to four years in prison on meth charges.The son, Robert Dale Hale, 29, entered guilty pleas before Circuit Court Judge Bart Stanley to charges of manufacture of meth, delivery of drugs, and simple possession of drugs. He was directed to serve four years along with the balance of the probation he violated. The highest charge, that of aggravated arson, was dropped as a result of the plea agreement and lack of evidence regarding the arson charge.The charges were leveled against Hale after the Bratten Street home of his father, Wayne Hale, caught on fire.
