Pennsylvania nurse accused of killing 2 patients said she felt bad for "their quality of life," according to officials

A nurse in Western Pennsylvania was charged on Wednesday with two murder counts for allegedly administering large doses of insulin to her patients, killing two men, said the state's Attorney General Michelle Henry.

Heather Pressdee, 40, was working at Quality Life Services, a nursing facility in Chicora, when she administered insulin shots to a 55-year-old man and an 83-year-old man because she felt their "quality of life was not good," according to a police affidavit.  

Pressdee also allegedly administered insulin to a third victim, a 73-year-old man, who survived after emergency hospitalization, said the affidavit.
