Kimberly Sipp, 23, was last seen around January 1, 1999, in Milwaukee, Wisconsin. She is described as an African-American woman, 5 feet 7 inches tall, weighing 135 to 150 pounds, with black hair and brown eyes. Her tattoos include a rose on the right forearm, the word love across the fingers of the right hand, and the nickname Kim on the upper right arm.

She may have used the aliases Tanya Austin or Tanya Austion and an alternate birthdate of September 20, 1978. Very little is known about the circumstances of her disappearance, and she has not been heard from since. Authorities continue to seek information that could help provide answers.
