The son of Springdale pawnshop owner slain in 1974 says he doesn`t understand Governor Mike Huckabee`s plan to commute the life sentence of his father`s killer. Huckabee said this week that he favored commuting the sentence of 47-year-old Dennis Lewis to time served. Lewis was 17 when he shot and killed J-J Cobb during a robbery. Cobb`s son, Dan Cobb of Springdale, says he was under the mistaken impression Lewis would never get out of prison. The state parole board also reccommended clemency for Lewis. A board spokeswoman says the family should have provided current addresses so that they could have been notified of the hearing and objected to Lewis` release.
