Delaware police have identified human remains discovered in 2011 as belonging to Hannah Graham Kleitz, a woman who died in 1907. The remains, which included a skull, were found in the woods of Sellers Park in Wilmington in June 2011. On Saturday, New Castle County Police confirmed that the remains belonged to a 29-year-old white female who died from a medical illness. The identification brought closure to a case that had remained unsolved for over a decade. When the remains were first discovered, police had limited information to identify the individual, estimating the person was between the ages of 25 and 50. A DNA profile was taken, but no identification was possible at the time. In 2019, the Cold Case Squad revisited the case, citing advancements in DNA technology and forensic science as a reason to re-examine the remains. To aid in identification, investigators created a three-dimensional scan of the skull and sent it to Joe Mullins, a forensic art professor at George Mason University. Mullins used the scan to build a facial reconstruction by adding muscles, tissue depth markers, and facial features such as the nose and lips to a skull mounted on a framework. This process helped generate a visual representation of what the individual might have looked like. In the meantime, investigators reached out to people across the country who voluntarily shared ancestral information and DNA profiles to help locate potential relatives. A potential familial connection was identified last January through a genealogical tree. This relative informed authorities about a woman whose mausoleum and grave at Riverview Cemetery in Wilmington had been illegally accessed and desecrated in 2002. Remains similar to those found at Sellers Park had been removed from the grave. Through DNA comparison, investigators confirmed the remains belonged to Hannah Graham Kleitz. On August 27, Graham Kleitz's extended family and authorities gathered at Riverview Cemetery to return her remains to her mausoleum. The New Castle County Division of Police thanked those who contributed to solving the case and providing closure to the family. Authorities have not confirmed whether anyone has been charged in connection with the desecration of Graham Kleitz's grave.
