Name: Emma Cordero
Birthdate: 17 August 1985

Emma's father was a police officer, killed in the line of duty when she was fifteen and her brother was nineteen. Manuel was killed by his partner during a foot pursuit, and though there were hints that the other officer was on the take, the investigation eventually ruled that Manuel's death was accidental and his partner was cleared of any wrongdoing. Manuel's wife Patricia blamed him, however, and his attempts to visit afterwards and to give the family money to help with expenses were rebuffed.
A few years later her brother was working his way through law school, and already showing promise as an attorney. Despite Patricia's insistence that both her children could get a college education if that was what they wanted, Emma knew that her mother was already working much too hard for her children. Deciding she would rather help the family financially, Emma joined the force after graduation.
But things went wrong at the Academy almost from the start. Her father's former partner had since earned the rank of captain and thanks to him it was generally believed that it was Manuel who had been the dirty cop. As word got out who Emma was, she took more and more flak from fellow cadets and even officers. She was ready to quit, but decided that would only confirm the rumors and toughed it out.
Once an officer herself, she began to realize the full extent of the corruption. Most of it was small in itself, but together it added up to a police force that seemed rotten to the core and she wanted to do what she could to fix it. Thanks to her situation, she decided the best thing she could do was to set herself up as a sort of double-agent, acting the part of a cop on the take to gain trust, then quietly turning in the worst offenders.
This was easier said than done, however. To play her role, she often had to break her own moral code, and found herself drifting slowly away from her family. Worse, as months turned into years with no end in sight, her mission seemed more and more hopeless. It would be so much easier and simpler to give up her double life and become what she seemed to be, and with little to no outside support that idea was supremely tempting. Making the rank of detective, as she recently had, only made it easier to cover things up, until she felt completely torn in two.
(Note: Her undercover mission can be semi-official but off the books, where only one higher-up knows what's going on, or something she's doing on her own -- whatever's easiest. Also, I'm terrible at finding character images so I'm still working on that part.)
