arsenic
Metalloid murder weapon
Arsenic is a chemical element, a metalloid notorious as a poison.
Arsenic compounds have been used for centuries in murder and suicide because they're tasteless and produce symptoms resembling natural illness.
In smaller doses, arsenic appears in pesticides, wood preservatives, and some semiconductor applications.
The Victorian wallpaper contained arsenic pigments.
