The Disappearance of Barbara Miller

Barbara Miller was reported missing by her estranged ex-boyfriend on July 5, 1989, after attending the wedding of her best friend, Lori Wands, in Mifflinburg on June 30.
In 1990, Sunbury police first reported they believed Barbara Miller may have been murdered. Police began interviewing potential witnesses, including Mike Egan, a former Sunbury police detective who was also her boyfriend at the time.
This is a shorter episode but an interesting one.
