Jean Tuggy, 60, of Pine Grove Mills, Pennsylvania, was shot and killed in her home on January 21, 2016. Tuggy worked as a school bus driver and served as a church librarian; family and friends remembered her friendly nature and that she had battled cancer.

The homicide went cold for years before investigators reopened the file. They identified Christopher Kowalski, a former Wegmans coworker who had befriended Tuggy and become romantically interested in her, as a potential suspect. Kowalski once owned a 9mm pistol that he later sold; the firearm was traced to a subsequent owner and examined for similarities to the murder weapon. Agents from the Pennsylvania Attorney General’s Office located and interviewed Kowalski, and he admitted to the killing before being arrested and extradited to Pennsylvania for prosecution.
