Police have arrested a second woman in connection with an incident last year in which a woman and her three-year-old daughter were attacked with acid outside an Oxon Hill apartment, authorities said Thursday.

Tamara Chrystal Jackson, 30, of D.C., is charged with first-degree assault and other related counts in the March 29, 2010, incident, believed to be a “domestic-related assault,” authorities said. Another woman, Tikia Shauntice Anderson, of Greenbelt, had already been charged with similar offenses earlier this year.

Police said in a news release that Jackson, who was arrested Wednesday, is believed to be the “final suspect” in the case.

The attack occurred in an apartment parking lot in the 1100 block of Kennebec Street, police have said. The victim was burned on her face, thigh, neck and both of her eyes, police said, and her daughter was burned on the head and below an eye. Both were hospitalized in stable condition after the incident.
