Outside the church police found two discarded bloodstained green shirts. Police collected dozens of blood samples to be processed as part of the investigation into the attack, according to an inventory. Search warrants indicate that investigators expect to find additional evidence at addresses connected with the suspected shooter. Among the items police expect to find, according to a search warrant, are weapons including firearms, explosive materials, ammo and financial records indicating how Westman obtained weapons. Investigators also hope to uncover what motivated the shooting. Other items police expected to collect from Westman's residences were cell phones, laptops, memory cards and any written documents, including a manifesto or "notes referencing planning, motive, targets, ideology, or grievances."
