  The day after the shooting, 35-year-old Rickard Andersson (born 10 August 1989 as Jonas Rickard Simon) was identified as the shooter and had acted alone. Andersson had always lived in Örebro and had been enrolled at Campus Risbergska in 2013 and applied for a mathematics course in 2019, but exited the course in 2021. His residence was found to have been barricaded when it was raided by the police. Prior to the shooting, Andersson sold or attempted to sell his personal belongings, researched how to clean firearms, bought ammunition, bought smoke grenades (which he would use in the shooting) and acquired the guitar case he would use to store his weapons in to bypass into the school. Andersson had acquired a firearms licence in 2011, which he bought three out of the 4 firearms he owned in the same year. The four firearms were: a Browning BAR (.30-06), a Ruger 10/22 (.22 LR), a Mossberg 590A1 (12-gauge) and a Winchester 1300 (12-gauge). He had no prior criminal convictions. He was also reported to be living reclusively since 2016 and was unemployed, receiving money from government health care benefits.
