[6] Klug's parents later separated and Löffler eventually relocated to South Africa with her new life partner and Elisa to work for a local Scientology branch.
[8] At the time of her disappearance Klug was studying architecture at Leipzig University of Applied Sciences and had gone on a semester abroad to Amman.
[11] For the same evening she had an appointment with a friend in Halle (Saale) to attend a public movie screening which was part of an event called Herbstsession at the local art school campus.
[13] Klug had booked a plane trip to Jordan including tickets for the journey to the airport prior to her disappearance.
Since detection dogs were able to register her scent at a bus in Leipzig, at the Günthersdorf IKEA and at the Neuwerk campus of Burg Giebichenstein Kunsthochschule in Halle[16] (where she was supposed to meet her friend later on the day of her disappearance),[17] investigations at first focused on an excavation hole on campus which was sealed the day after her disappearance.
In the basement of one of the buildings on the campus a detection dog gave a bark that signaled the smell of a corpse from a newly-installed AC that was connected with the excavation hole.
[10] About three months after her disappearance divers checked the Mühlgraben, a branch of the river Saale that runs close to Burg Giebichenstein, without results.
[18] Police also conducted an extensive survey of the surroundings of the IKEA store in Günthersdorf[10] where more than 60 volunteers supported the effort.
[11] Three weeks after her disappearance police divers searched the Saale Elster channel near the IKEA as well as a nearby lake.
Police has highlighted the fact that Klug is a close family member of a high-ranking Scientology executive who left the church.
Klug's mother and sister are currently unaccounted for as well since police were unable to trace them after their relocation to South Africa.
One witness claims to have seen Klug on the day of her disappearance around 3 p.m. at the tram station Richard-Lehmann-Straße/Hochschule für Technik und Wirtschaft, just two stops from Südplatz, talking to a man about visiting IKEA.
According to another witness, a truck driver, Klug walked alongside the Saale Elster channel in Günthersdorf, close to the IKEA store, and from there across a bridge in the direction of the road Bundesstraße 181.
On a parking lot located between the bridge and the main road she might have stepped into a car with an Esslingen license plate.
[28] The main trails are heavily frequented but Klug's remains were found in a remote spot that prevented discovery for over three years.
