The Kane County Coroner's Office has identified the skull found in 1978 in a Batavia home as belonging to Esther Granger, a 17-year-old who died in Merryville, Indiana, in 1866. Granger's remains were likely the result of a grave robbery, a practice common at the time, possibly for medical study purposes. The discovery was made during a home renovation, and the skull remained unidentified until modern DNA technology and forensic genetic genealogy confirmed its origin. The identification process involved matching the DNA from the skull with that of Granger's second great-grandchild. Despite solving the mystery of the skull's identity, how it ended up in Batavia remains unclear. This case highlights the advancements in forensic technology and its role in solving historical mysteries.
