Authorities are continuing their investigation into the deadly shooting at a Minneapolis Catholic school that left two children dead and 17 others wounded on Wednesday. The suspect, identified by police as 23-year-old Robin Westman, was found deceased in the school parking lot from an apparent self-inflicted gunshot wound.

Westman left behind a handwritten journal that was posted online shortly before the attack. The New York Post, which reviewed a translation of the writings, reported that the journal included reflections on gender identity as well as expressions of regret and personal conflict. In passages cited by the outlet, Westman described struggles with self-image and vacillation over gender expression.

The writings also reportedly contained violent statements, including references to past mass shootings, and videos linked to the suspect appeared to display political slogans and threats written on firearm magazines. Authorities have not independently verified the authenticity of all the materials, but confirmed they are under review as part of the broader investigation.

Police say Westman legally obtained the rifle, shotgun, and pistol used in the attack. The FBI has opened a case treating the incident as both a potential act of domestic terrorism and a possible hate crime against Catholics.

Westman’s mother previously worked at the school as a secretary before retiring in 2021.

Community leaders and investigators have urged the public not to draw broad conclusions about Westman’s identity or motives until the investigation is complete. Authorities are expected to provide further updates in the coming days.
