After graduation from a local high school, he moved to Kraków, to begin studies at the renowned Jagiellonian University.

Some time in 1976 Pyjas joined the Workers' Defence Committee, the organisation which was created to help labourers, participants in the anticommunist street protests in Radom and Warsaw.

Pyjas’ body was found on 7 May 1977, in the staircase located in a building at 7 Szewska Street in Kraków’s historic centre.

Three different investigations, carried out by the local prosecutor’s office and Milicja Obywatelska, stalled and finally ended, due to lack of evidence.

Bronisław Wildstein stated that he bribed a worker at the mortuary in Kraków and entered the premises, to check the body of his fellow student.

[9][11] Maleszka was a highly praised agent, whose reports on students in Kraków, in which he did not hesitate to describe the intimate lives of his closest friends, were called excellent by his secret service bosses.

On 23 September 2006, Pyjas was posthumously awarded the Commander's Cross of the Polonia Restituta, by president Lech Kaczyński.
