My comment:
(a) I view English- and German-language news reports on this topic (all published in the past two days), none of which carries a photo or video that is from this investigation. All photos in these reports are from data bases (unrelated to this case). Local police has not released the name of the suspect.
(b) The English version of the report also says "lead acetate." The term applies to "lead(IV) acetate" and "lead(II) acetate."  Both are poisonous to humans due to lead, not to acetate), but the former is colorless whereas the latter, white. Lead(II) acetate may be absorbed through gastrointestinal tract, lung after inhalation, and eye/ skin, all causing irritation in these three sites.
