Former Pennsylvania nurse sentenced to life for killing three patients

Heather Pressdee admitted to intentionally injecting excessive doses of insulin into 22 patients across the Pittsburgh area

A former Pennsylvania nurse has been sentenced to life imprisonment after admitting she intentionally injected nearly two dozen of her patients with excessive doses of insulin, killing three of them.

Heather Pressdee was sentenced on Thursday in a Butler county state courthouse near Pittsburgh, where nearly 40 of her victims' family members spoke about how her crimes upended their lives, according to a news release that prosecutors issued at the conclusion of a case that highlights how frighteningly vulnerable patients can be in healthcare settings.
