Dr. Alexx Woods (played by Khandi Alexander) worked as a doctor in New York, but eventually came to Miami, where she began work as a medical examiner for the Miami Dade Police Department.

Dr. Woods is a very conscientious medical examiner who has a habit of appearing in lighter or even white clothing at a crime scene to carry out the first tests.

Furthermore, she has the habit of talking to the dead. This is a way to express her sympathy and get through to the victims by daily contact.

Alexx Woods is a great support for Lieutenant Horatio Caine, with whom she also has a private friendship, with their professional work. She tries to keep her private life strictly separate from work; Alexx is married and has two children.

In the sixth season of CSI: Miami, her son becomes the prime suspect of a murder case. These events lead to doubts about her work and colleagues. Finally she makes the decision of resigning as a pathologist from the Miami Dade Police Department and leaves the team.

Through her work in a hospital emergency room, she hopes to find an emotional return to herself. The contact between Alexx Woods and her friend and former colleague, Horatio Caine, is not turn completely because they still see each other professionally.

Actress Khandi Alexander retired in the seventh season on her own request from the series.
