"Dr. Death" refers to Christopher Duntsch, a former neurosurgeon in the United States who gained notoriety for his malpractice and criminal activities. Between 2011 and 2013, he performed numerous surgeries that resulted in severe complications, paralysis, and even death for several patients. His actions raised significant concerns about medical oversight and patient safety. Duntsch was ultimately convicted of aggravated assault and sentenced to life in prison in 2017. His case prompted discussions about the need for stricter regulations in the medical field and led to increased scrutiny of medical licensing boards and hospital protocols to prevent similar incidents in the future.
