Colorado plastic surgeon Dr Geoffrey Kim turned himself in this week after Colorado authorities charged him with first-degree aggravated assault and criminally negligent homicide – both felonies – in the death of patient Emmalyn Nguyen, 18.

Dr Kim performed breast augmentation surgery on the teenager at Colorado Aesthetic and Plastic Surgery in August 2019, but she went into cardiac arrest after being administered anesthesia. She fell into a coma and died 14 months later.
