Marguerite Peggy Laskovich, an 80-year-old woman from Pittsburgh, died on January 21, 2023, after a stay at Sunnyview Rehabilitation and Nursing Center in Butler Township, Pennsylvania. Her family says her condition declined rapidly while at Sunnyview; two days before she died her son Keith found her bloodied with broken teeth and two black eyes, and they later alleged she appeared overmedicated. With several relatives present near the end, a nurse identified as Heather Pressdee gave Marguerite an injection that the family believes was a lethal dose of short-acting insulin, and Marguerite died shortly afterward.

Marguerite’s death became linked to a wider investigation into Pressdee, who prosecutors later said intentionally administered excessive insulin to multiple medically fragile patients across facilities in several counties beginning in 2020. The family filed a civil suit against Sunnyview alleging failures in hiring, supervision and response to warning signs about Pressdee’s employment history and conduct. Marguerite was remembered in her obituary as a Pittsburgh-born retiree who worked in business and customer service and was active with dog-breeding and conservation groups.
