Since the beginning of the 1980s, Larsen wandered throughout the country, burgling hundreds of cabins and lodges, often spending several nights in the process, all the while avoiding law enforcement.
After school, he went to Copenhagen and joined the Danish club Fremad Amager, but soon dropped out and started living on the streets.
By mid-August, the search for Larsen had turned into a large manhunt, involving the police, hunters, cabin owners and local volunteers, all scouring the forests and wilderness and conducting 24-hour patrols of popular hiking areas, searching for any trace of the notorious criminal.
[4] On 19 August, after receiving dozens of reports of forced entries, Norwegian police started plotting Larsen's itinerary on the map.
The plan worked, and they managed to track Larsen down when a police patrol found him walking on the mountainous border between Lom and Skjåk.
He was handcuffed and escorted under heavy guard a few kilometers through the steep and difficult terrain to the nearest road, before being transported back to prison in Hønefoss.
In 2007, he was brutally assaulted by a fellow inmate after an altercation, causing him to suffer a cerebral hemorrhage, requiring life-saving surgery.
On 23 July 2013 however, when the Kirkvoll family entered their mountain lodge at Geilo they found it broken into and vandalized.
[7][12] Owners have also described scenes of vomit and urine, while leaving a "signature" of excrement on the living room floor was considered Larsen's trademark.
