What else do we know about the suspect?
In an interview with the Aftonbladet tabloid, a relative of the suspect said he had not had much contact with family in recent years and was unemployed. "As a child he was different but lively," the relative said. "He did well at school. But recent years were tough for him." Another relative said the suspect, who reportedly changed his surname eight years ago, was a "recluse" and may have had mental health problems. They said: "Before, he had a friend he spent a lot of time with, but not now. He wants to be on his own. He doesn't seem to like people much." Hours after the attack, heavily armed officers raided a flat in Orebro believed to be registered to the man, using drones and a ladder truck, according to Swedish Radio. The broadcaster found he had no convictions to his name and had declared no income over the past few years.
