Leslie Hamilton, Terminator actress Linda Hamilton's twin sister died in New Jersey on Aug. 22. She was 63 years old. Leslie unexpectedly passed away in New Jersey on Aug. 22, according to an obituary from the Burlington County Times. She "passionately worked as an ER nurse, and ultimately transitioned to working as a hospice nurse later in her career," the obituary read. Her cause of death was not disclosed. Leslie served as a double for her sister in her only film credit, 1991’s Terminator 2: Judgement Day, in which Linda portrayed Sarah Connor. Leslie also portrayed her sister's reflection in the mirror in one scene. She is survived by sisters Linda, Laura Hamilton, and brother Ford Hamilton, in addition to three children and two grandchildren. 

Leslie was described as "the consummate caretaker, and devoted her life to helping her children and the lives of others." "She was an avid fisherwoman through the years, and was not shy about out-fishing anyone who joined her," her obituary continues. "Above all, she cherished the time spent with her family and friends, and will be deeply missed by those she leaves behind." Memorial contributions in Leslie's name may be made to Samaritan Hospice at samaritannj.org/giving. She is survived by her three children, Ashley, Adam and Kendall, as well as twin sister Linda and their older sister and younger brother. After almost three decades away from Hollywood, Linda finally agreed to once again play Connor in 2019's Terminator: Dark Fate. “In terms of what we built, it went far beyond my wildest dreams. That doesn’t mean I want to go and do another one. Once is probably enough," she said in October. That appearance in Terminator 2 was Leslie's sole film credit. She "passionately worked as an ER nurse, and ultimately transitioned to working as a hospice nurse later in her career," the obituary states.
