LANSDOWNE, Md. (WJZ)—A second woman is now facing charges in connection with a chemical attack inside a Wal-Mart in southwestern Baltimore County.

A grand jury charged Ebony Odoms for her role in the chaotic scene.

Police say Odoms and Theresa Jefferson threw bleach, Pine-Sol and other cleaning chemicals at each other inside the Lansdowne store.

Fumes from the chemicals sickened 19 people.

Odoms’ lawyer says she was acting in self-defense.
