His life and violent death led to ongoing conflicts in his home town and have been depicted in movies and books.
Walder's home community is a Streusiedlung with various farms spread out on the Kirchweiler Kalkstein in the Tauern mountains at an altitude of 1,640 metres (5,380 ft).
On 8 September 1982 he was observed at dusk with blackened face and carrying a rifle, and was shot by Johann Schett, a forester and state hunter.
Schett was later sentenced to three years in prison for Körperverletzung mit tödlichem Ausgang (a lower grade of manslaughter) and was released after 18 months.
[5] The brothers' ongoing anger about the alleged murder and their continued claims about the lack of justice were the topic of books and films.
The brothers received fines for distributing flyers with an image of the dead Pius at the High Tauern tunnel entrance.
[10] Tatort is the longest-running German-language television series of that sort, set in various parts of Germany, Austria and Switzerland.
[11] The TV production staged the deadly shots on 16 August and used the coincidence with the anniversary of the King's death to prove that Pius was murdered, since he never would have gone poaching on that day of memorial.
