BUFFALO, N.Y. (WKBW) — Michael Swinarski said he has lost sleep over what he alleges happened to his 70-year-old mother, Camillie Swinarski, while she was hospitalized at Buffalo General Medical Center.
Swinarski said his mother was particularly vulnerable at the time, having recently left the intensive care unit while continuing to receive treatment for health issues.

He said a hospital worker slapped his mother four times while she was lying in her hospital bed.
“What is possible to make somebody slap a 70-year-old woman that just got out of the ICU? I mean, what excuse would be tolerable, really?” Swinarski said.
Swinarski said he contacted Buffalo police after learning about the alleged incident.
Buffalo police confirmed to 7 News that Crystal Hennings, 50, of Buffalo, was arrested Aug. 15 and charged with two counts of harassment. According to the police report, Hennings was identified as a patient care assistant.
The police report states the alleged victim was slapped in the face with an open hand, causing pain.
Swinarski said another patient who was in the room with his mother witnessed part of the interaction. According to the police report, the witness reported hearing the worker speak to and belittle Swinarski’s mother.

Swinarski said the incident has been difficult for his family and that he worries his mother may not be the only person affected.
