according to the indictment, LaRose received a direct order to kill a citizen and resident of Sweden, and to do so in a way that would frighten “the whole Kufar [non-believer] world.”
The indictment further charges that LaRose agreed to carry out her murder assignment, and that she and her co-conspirators discussed that her appearance and American citizenship would help her blend in while carrying out her plans.
According to the indictment, LaRose traveled to Europe and tracked the intended target online in an effort to complete her task.
She was apparently recruiting as well.
