Broca Leibs was born on February 21st, 1985 in Lubeca, a small city in the northeastern part of North Rhine-Westphalia.

She moved to Paderborn to pursue training as a health and nursing student at St. Vincent's Hospital.

By the summer of 2006, she was 21 years old, living in a shared apartment at Borkenerstrasse 56 with her former boyfriend, a man named Christos Karoulis.

They had dated for about five years before breaking up, but they remained close friends and continued living together.

Potterbourne is a mid-sized city of about 150,000 people in eastern North Rhine-Westphalia, roughly equidistant from the larger cities of Bielefeld to the north and Kossel to the south.

This triangle of towns—Potterborn, Nieheim, Liechtenau—this will become the geography of Froka's final days.

On the afternoon of June 20th, 2006, Froka had lunch at a restaurant with her mother, Ingrid, as well as her ex-boyfriend slash roommate, Chris.

While they were eating, she received a text message from a friend named Isabella, inviting her to the Irish pub The Old Triangle to watch the World Cup match.

During the game, she exchanged text messages with a man named Niels, a recent acquaintance introduced through some mutual friends.

There was no romantic relationship between them, but they had been chatting regularly.

She borrowed a friend's battery, used it for a while, and returned it before she left.

She left the pub at approximately 11 p.m. She reportedly had about five euros in her pocket, not enough for a taxi.

Her apartment was about a kilometer and a half away, a walk of perhaps 15 minutes.

The total distance of the walk back to the apartment was about a mile, through the city center of Potterbourne on a warm June evening during the World Cup.
