Nancy Grace will reportedly leave her show on the HLN network in October. The CNN sister station explained that Grace told her staff on Thursday that her show will be ending after 12 years on the air. The 56-year-old Grace added in a statement that she'll be leaving "with a full heart and endless gratitude." Grace hasn't announced any new plans, and HLN has not yet announced what type of show will replace hers. Ken Jautz, HLN's chief executive, said on Thursday, " Nancy Grace gave a voice to the voiceless and we are extremely grateful for her contributions to the network."
