A Colorado plastic surgeon on Wednesday was found not guilty of the most serious charges he faced in a teenage patient’s death, but was convicted on less serious counts after a week-long jury trial in Arapahoe County District Court.

Jurors found Dr. Geoffrey Kim not guilty of negligent homicide in the death of 19-year-old patient Emmalyn Nguyen, but found him guilty of attempted reckless manslaughter and guilty of obstructing a telephone after he failed to call for help for hours after Nguyen suffered cardiac arrest.

Attempted reckless homicide is a Class 5 felony in Colorado, which is typically punishable by between one and three years in prison. Obstructing a telephone is a misdemeanor. Kim is set to be sentenced on Sept. 8.

Nguyen went to Kim for breast augmentation surgery in August 2019, when she was 18, but she suffered cardiac arrest after receiving anesthesia, fell into a coma and died 14 months later, in October 2020.

Prosecutors argued that Kim caused the Brighton teenager’s death when he failed to call for help for five hours after her cardiac arrest, even though she needed immediate care at a hospital, which was better equipped than Kim’s outpatient surgery center, Colorado Aesthetic and Plastic Surgery in Greenwood Village.

His defense attorneys argued during the jury trial that a nurse was actually to blame for Nguyen’s death. They said that anesthetist Rex Meeker gave the girl a mix of dangerous drugs before her surgery and a much-too-large dose of fentanyl that together stopped her heart.
