Greene County 911 operator, Leon Price, faced a preliminary hearing Monday after being charged in connection with the death of a woman whose daughter had called for an ambulance that prosecutors said Price never dispatched.Price was held for trial on charges of involuntary manslaughter, recklessly endangering another person and obstruction. A charge of official oppression was dismissed by the judge.The woman, Diania Kronk, was severely ill, and 24 hours after her daughter contacted 911, her son called back to report she was dead. "The county detectives' investigation revealed that 911 services violated protocol and their own procedures by refusing to dispatch an ambulance to Ms. Kronk's aid," Greene County District Attorney David Russo said in a recent statement. "It is alleged Ms. Kronk's death is a direct result of 911's violation of those policies and procedures."Days before the charges being filed, Kelly Tichenell filed a lawsuit against Price and two supervisors. Titchenell told Pittsburgh's Action News 4 she asked the dispatcher if her 56-year-old mother, Diania Kronk, had been drinking heavily, was unable to walk or speak, and was turning yellow.The complaint alleges Price asked several times if Kronk would be able to give consent to go to the hospital, and Titchenell insisted she would.On the 911 call recording provided by the Green County District Attorney's Office, the dispatcher, who the lawsuit says was Price, told Tichenell to call 911 back after making sure her mother would go with the ambulance before resources would be sent.The forensic pathologist who conducted Kronk's autopsy testified during Price's preliminary hearing that Kronk would not have died the following day if she had received medical help when her daughter called 911."I said my mother’s going to die, and she died less than 24 hours later," Titchenell said. "I wanted him to be held responsible, and I knew it wouldn’t happen if I didn’t go after Greene County, and I was right, it took a lawsuit two years later to file charges.”Greene County District Attorney Dave Russo said according to the investigation,Diania Kronk was denied medical services when every ambulance in service that day was available for dispatch. In the DA's statement, there was no indication as to why an ambulance was not dispatched.
