|Significant Other/s||Howard Peterson (affair)|
|Portrayed by||Unknown actress|
Sara Manning was a young woman living in New York City, and the victim in the episode "Nanny McDead". She was murdered by her friend Chloe and stuffed in a dryer after it was revealed that the two were having an affair with the same man.
Sara originally came from Atlanta, Georgia, and had been college friends with Chloe and Brent Johnson, her own boyfriend later. Since Sara worked for the Petersons, it at first seemed that Howard Peterson was the man she was sleeping with, but his affair turned out to be with a work colleague of his own. Sara's case was the first one that Castle saw from beginning to end, and Beckett's handling of it set much of the tone for his portrayal of Nikki Heat.
