A white nationalist Norwegian who killed his stepsister and then stormed an Oslo mosque and opened fire, hitting no one, was found guilty Thursday and sentenced to 21 years in prison, the longest jail term under Norwegian law. Philip Manshaus, who had said in court that he regretted not having caused more damage, “has proven to be an extremely dangerous person,” prosecutor Johan Oeverberg said as he demanded the maximum penalty. On Aug. 10, 2019, Manshaus, 22, killed his 17-year-old stepsister, Johanne Zhangjia Ihle-Hansen, by shooting her four times with a hunting rifle at their home in the Oslo suburb of Baerum.
