Kristen Kramer is an intern at the Central City Police Department, and works in the crime lab, along with Barry Allen.
Kristen Kramer was created by Geoff Johns for his run on The Flash.
Kristen was given a name and a profile picture along with the rest to the Central City Crime Lab in The Flash: Secret Files and Origins 2010, and was set to be an important part of Barry Allen's future. This never seemed to happen. Kristen was seen as a member of the Crime Lab in the first issue of The Flash, but only as a back ground character when Captain Frye introduces Barry to his co-workers.
