We have yet to find out anything about Claire's past. Claire is a professor at the university where Joe once worked before he went to prison. In 2002, Claire told Joe that she was pregnant with their son Joey. Claire is the one who told Ryan to go to Joe when Ryan had a question on the murder case not knowing Joe was the one he was looking for. Once Claire found out the truth that Joe was the killer, she divorced him and got custody of Joey. Claire made the first move when it came to her and Ryan. Claire meets Ryan's sister Jenny who tells him that she likes her. It is sometime after that Ryan ends their relationship because he wants more for her and Joey.
After her ex-husband, whom she calls a madman, kidnaps their son, he sends men to kidnap her too. So she is put under protection, then Ryan takes her into hiding. Before she willingly gives herself up to her husband's men in order to see her son, she and Ryan reaffirm their love for each other. Her favorite food is potatoes. Claire tells Ryan that Joe wrote her a letter. When the FBI told Claire about Joe's escape, the only one she wanted to talk to was Ryan. She was murdered by Ryan's on and off lover Molly.
Claire was murdered by Molly. Molly was Ryan's ex- girlfriend. The murder took place by Molly hiding in Ryan's apartment and fake knocking on the door from the inside. Molly then grabbed the knife off of the table and stabbed Ryan in the abdomen. Claire exited the washroom and saw Ryan. She panicked and went to run to Ryan's side, only to be stabbed twice by Molly, once in back and then in the chest. Ryan then stands to attack Molly and strangles her before snapping her neck. Afterwards Claire dies from her wounds in the hospital.
