[3] Lindbäck was enrolled at Uppsala University on 2 February 1829 and was later ordained there on 19 December 1831, immediately after his graduation he was hired by the Church of Sweden as a curate for the parish at Skållerud and simultaneously acted as headmaster at the local school which was funded by the nearby ironworks.

It was a wealthy farmstead and the profits made from it gave Lindbäck the opportunity to give both his sons a proper education, both becoming officers in the Swedish Army.

After accepting the position as vicar in the parish of Silbodal, Lindbäck was given the unenviable task of caring for a group of 40 people who were supposed to receive poverty aid from the church.

Lindbäck sought to relieve the pressure these expenses were putting on his parish and thus began to push through a number of regulations and ordinances in an effort to lower these costs.

A little over a month later on 30 November 1864, a farmer named Nils Pettersson was the second person to die after a visit by Lindbäck, followed by Anders Lysén on 15 December 1864.

[citation needed] Suspicion quickly landed on Lindbäck, as he had been one of the last people to be in close proximity to Lysén before his death, and it was also discovered that several burials at the local church had been conducted unusually fast.

[citation needed] Lindbäck was arrested and brought to stand trial at the Nordmark district court where he confessed to his crimes but attempted to defend his actions by saying they were intended as an act of mercy.
