Charleston County Emergency Medical Services Chief Don Lundy has been placed on administrative leave with pay while the county “investigates an internal Human Resources matter,” according to a county spokesman.

The spokesman, Shawn Smetana, writes, “Because this inquiry involves personnel matters, we will not have further comment at this time.”

The news comes shortly after Lundy self-published a book titled Paramedic of the Heart: True Stories of Lives Changed. According to Amazon, the book was published July 7. The product description reads:

“The patients he bonds with, the humanity he witnesses, the kindness shown to one another, as well as the damage caused to each other, is shown in these chapters. Personal stories about trials and tribulations, either from Don’s viewpoint or that of his patients, helps you to understand what it is to be a paramedic.”

The book has drawn some criticism, particularly for how Lundy describes four of his employees, whose names are not given. At one point, Lundy writes, “They are life-sucking, energy draining bags of annoying hell. And, for their own misgivings, everyone around them must suffer.”
