Casey Smith

Casey Smith is a female human from the planet Earth (also known as Sol 3). She was born on December 14th 1984 and is 25 when she meets the Doctor in 2009.

Childhood
Born into a two-parent family, Casey had a regular upbringing in North London. She had an older sister, Anna, but her whereabouts is currently unknown. She attended Coal Hill School which she left to study at college. She then dropped out of college to get a job as a fashion model, which did not work out.

Adulthood
With no job or qualifications, Casey moved back to her mum, with her dad having left her mother a year in advance not long after Anna disappeared. Casey then started a career in a local hair salon, but the pay was not that good and she longed to travel.

In 2009 she met the Doctor when investigating a newly opened and suspicous business in the local neighbourhood, DW: Changed World.

She travels to the 1980s and discovers a mysterious alien song which steals the lives of anyone who hears it, DW: Death by Music and visits her own grave in 2031, DW: This is Your Life.
