The first allegation of harming a patient came a year later when Leora Froelich underwent surgery at St. Luke's, according to records obtained by the News Tribune. Konasiewicz later admitted to having moved in the patient's spine during the procedure and appeared in court for the first time in a criminal case in Duluth in June of that year. In this case, St. Luke's neurosurgeon Robert Donley testified against him, as did Dr. Haugen.
Donley, who was treating Froelich at the time of her testimony, was surprised that Konasiewicz only realized the damage she had been doing after some time. After being informed of Kon and his other cases of misconduct, Abare said he did not understand why KonaSiewicz was still allowed to practice.
