"I believed what they told me," Baker told King 5. "That my daughter was dead." Advertisement Baker had already started working on her daughter's obituary when she found out that Samantha Rose Kennedy, 24, was actually alive. As the result of a terrible mix-up, Chief Medical Examiner Dr. Thomas Clark got Kennedy confused with the woman who actually lost her life, 25-year-old Aubrey Peterson. "We work in a gray area,” Clark said. "We did what we normally do. We thought it would be sufficient, but in retrospect, it wasn't." The distraught mother got the good news when the chaplain returned to her door. "He said, 'I'm sorry, but there's been a mistake,'" Baker said. "I cussed. I said, 'What do you do? Just go around telling family members they are dead and then say, oops, my mistake?'" Peterson’s family has been notified about her fate. “I don’t think anyone did anything wrong. It was a simple misunderstanding,” Clark told The News Tribune. “The appropriate response is to adjust your policies and practices to ensure something like this does not happen again. We are reviewing the circumstances and will adjust our practices.” Advertisement [King 5] [The News Tribune] Read More Thai court nullifies February general election, fueling political crisis Nine fisheries to blame for half of all drowned whales and wasted fish Turkish PM Erdogan vows to 'eradicate' Twitter, blocks access Mavs try to get back on track versus Nuggets With Putin's signature, Russia claims annexation of Crimea complete
