A doll-faced killer will get thrown in the box.

A sultry 23-year-old Colombian woman known as “The Doll” and labeled a “dangerous hitwoman” was arrested in connection to several targeted gangland killings — including the recent ambush murder of her ex-lover, according to local reports.

Karen Julieth Ojeda Rodriguez — known to police by the alias “La Muneca” (“The Doll”) — was cuffed for her alleged involvement in several high-profile murders in the municipality of Barrancabermeja allegedly carried out at the behest of the Los de la M gang, Spanish-language outlet Libertad Digital reported Thursday.
