Her first name is Corinne.
Corinne was sexually involved with Peter Hale and became pregnant. Knowing that she would lose much of her supernatural abilities to her offspring, she wanted to end the pregnancy but was talked out of it by Talia Hale. Talia took the baby from her immediately after the birth avoiding the possibility that Corinne would try to take back her power by killing the child.
After Malia was adopted, and with much of her power gone, Corinne became proficient with firearms and other weapons. She became an assassin and mercenary feared for her ferocity.
9 years later, Corinne returned to Beacon Hills and tried, unsuccessfully, to kill Malia by shooting at the car she was riding in with her adopted family. This incident caused Malia to transform and kill her adoptive mother and sister. Unbeknownst to Corinne, Malia survived.
Peter thought fleetingly about hiring her to kill the supernatural population of Beacon Hills while in his post-fire coma.
The U.S. Marshal service assigned Braeden to track Corinne down. She was unsuccessful and her obsession with the task seemed to end her government career.
