Jennifer O'Brien

Jennifer O'Brien was a Djinn, for nine years she had been working at the coroner's office, thus disposing of her victims bodies. She was also one of a rare type of Djinn, which fed of fear rather than blood.

History
Upon first meeting Dean and Charlie she simply seemed a strict stickler for the rules, and refused to let them see the bodies without the correct paper work. However the reall reason she had already had the bodies burned. The bodies were the victims of her son, who had just reached the age when he went out to hunt, and had messed up leaving the bodies behind.

Later while Sam, Dean and Charlie were sneaking into the coroner's office, Jennifer arrived to start work. Charlie distracted her, first by asking for a copy of the forms, they needed to have signed, claiming the local office had burnt down, then distracting her longer, by asking her fashion advice.

What Charlie was unaware of, was that she could smell fear, and desiding that she was scared enough to be a meal for both her and her son, she broke into Charlie's appartment, kidnapped her and took her to an abandoned warehouse where she and her son lived.

There upon Charlie accidentally reavealing she knew what she was, she guessed that they were hunters, she then intimated Charlie, before infecting her with her Djinn poison. Sam and Dean tracked her down, and arriving went searching for her, and Charlie. She confronted Sam, in his deterioated condition, she beat him down and was going to kill her, when Dean, who had snuck up behind her, stabed her with his silver knife, dipped in labs blood, thus killing her.
