Shania Costa (Blue Bloods)

Shania Costa (Jasmine Cephas Jones) is the hidden main villainess from "Justice Served," episode 4.08 of Blue Bloods (airdate November 15, 2013). She was introduced during the trial of DeShawn Williams, who was being accused of murdering Ella Martin, an 18-year-old deli cashier. 
Shania was identified as the main eyewitness to the murder, claiming to have seen DeShawn kill Ella. Detective Danny Reagan was part of the 12-person jury, and he was the only one who voted "not guilty" (with some others later following suit), due to the lack of evidence. After a new trial was ordered, Danny spoke to DeShawn, after which he and Maria Baez interviewed Shania, who repeated her claims. In addition to stating that DeShawn was Ella's killer, Shania added that she was inside a laundromat while the murder was committed, and she saw it through the window and witnessed Ella screaming and begging for her life.
Danny and Maria's trip to the laundromat revealed that Shania's claimed location was 200 feet away from the murder site, and the porch light was out and had been for a year. In addition, the owner of the laundromat revealed that a man named Jose Otero had been selling drugs in that same area, adding that he was arrested but quickly released on bail. A look into Jose's arrest revealed that the person who bailed him out was none other than Shania, and it ended up revealing that Shania was not only Jose's girlfriend, she was also Ella's true killer.
After both of them were brought into the station, it was revealed that Jose was engaged in an affair with Ella--who was also one of Jose's customers. An angry Shania found out about the affair and confronted Ella just as she was leaving work, and during the confrontation, Shania turned heel and stabbed Ella to death. The villainess covered up her actions by claiming that DeShawn (who arrived at the scene afterwards) committed the murder, and during her interrogation, Danny informed Shania that Jose was turning on her, as he was writing a statement that implicated her (after Danny told Jose to write down that he had no knowledge of the murder). Shania denied the detectives' claims, but she later confessed to killing Ella, attempting to claim that she was high on the drugs that Jose sold her and that they caused her to kill Ella, instead of her own jealousy. Shania stated that she wanted a lawyer, after which she was arrested (off-screen).
