Perpetrator
Owen "Oz" Lawrence (born Owen Lawrence Eames, c. 1986 – 28 April 2025) was 38 years old at the time of his death. He was reported as living in a flat on Wood Lane Court in Headingley. The property was raided by police following Lawrence's identification as the perpetrator. In 2000, when Lawrence was 14, he had legally changed his name to Owen Lawrence, omitting his former surname. He was named as the perpetrator to the wider public on 28 April 2025 following his death in hospital, with police also stating that he had acted alone during the attack. He was registered as disabled at the time of the attack.
An investigation into Lawrence's Facebook account showed that he had expressed misogynistic and other extremist views. Posts from an account linked to Lawrence had also showed hatred for ideologies such as Feminism and Islamic extremism. Admiration for Brenton Tarrant was also expressed by Lawrence, possibly linked to his animosity towards Islam. Lawrence also stated his love for various mass shooters, including Anders Breivik, Eric Harris and Dylan Klebold, Pekka Eric Auvinen, Vladislav Roslakov, Randy Stair, and Ethan Blair Miller.
Lawrence had at one point posted two selfies of himself. In one he was wearing a white shirt with the phrase "Natural Selection" printed onto it, similar to the shirt worn by Eric Harris during the Columbine High School massacre. In another, he wore a white shirt with a Jerusalem cross imprint, a possible reference to Breivik. In the hours prior to the attack, Lawrence had made a post to his Facebook detailing his plans.
Friends and neighbours of Lawrence expressed shock at his attack, stating that he never expressed any of his far-right beliefs. They also recounted how he had experienced drug addiction and once previously amassed a weapons collection, mostly knives, that his mother had taken away from him. Lawrence was known to have stalked his former fiancée, who had learning difficulties, after a breakup around four years previous to the attack.
