MEMPHIS, Tenn. (AP) — A Memphis gun dealer who already has been sentenced for killing a codes inspector has pleaded guilty to beating a Baltimore doctor to death with a hammer in another case.
Dale Mardis made the plea Wednesday for the June 1998 killing of Henry Ackerman and was sentenced to life in prison. It will be served concurrently with Mardis’ life sentence and 15-year sentence for shooting code officer Mickey Wright in 2001, then burning his body and putting his remains in junked cars that were later crushed.
Ackerman had been in Memphis to purchase a truck and got into an argument with Mardis over a debt. They knew each other from gun shows.
