On February 5, 2015, 14-year-old Katelin Lorraine Williamson of Hartford City, Indiana, was found dead inside her apartment and her father, 40-year-old Shane Paul Williamson, was found shot in the apartment complex parking lot. Both deaths were described as a brutal double homicide. Katelin, born July 11, 2000, was a freshman at Blackford High School who enjoyed music, art, and spending time with friends.

Police identified 59-year-old Charles R. Whittington of Portland, Indiana, as a person of interest and took him into custody the day of the killings. He was charged with two counts of murder; court filings entered a not guilty plea on his behalf. At trial the prosecution presented a motive tied to anger over Shane Williamson’s online communications with Whittington’s former girlfriend, and evidence that Whittington broke into the apartment, shot Katelin, then waited and killed Shane when he returned.

The community was left mourning a daughter and father taken in the same attack. Does anyone have information about Katelin, Shane, or that February 2015 evening that could help fill gaps in the timeline?
