A lesbian member of the New Hampshire National Guard who fought the Defense of Marriage Act while battling incurable cancer finally succumbed to the disease early Sunday morning. Chief Warrant Officer Charlie Morgan died at age 48 after fighting not only cancer, but working on behalf of LGBT rights as a plaintiff in a lawsuit against DOMA and an outspoken activist in favor of marriage equality. The LGBT military group OutServe-SLDN announced the news of her death on Sunday. Calling Morgan a “courageous fighter,” Allyson Robinson, executive director of OutServe-SLDN, thanked those in a statement who had supported Morgan as well as her spouse Karen Morgan and daughter Casey Elena. “She made an indelible mark on everyone she met with her integrity, her positive outlook, and her unflinching commitment to righting the wrongs visited upon gay and lesbian military families,” Robinson said. “The fight for full LGBT equality in this country is forever changed because Charlie Morgan took up the cause.” In September 2011, Morgan was diagnosed with stage-four incurable breast cancer. After being first diagnosed with the disease in 2008 and undergoing a double mastectomy and chemotherapy, Morgan was declared cancer-free and was deployed to Kuwait, but was later informed her cancer had returned and had to undergo further treatment.
