An ongoing police investigation has yet to reveal why Robin Elizabeth Yevick was stabbed to death in downtown Memphis on Sunday, April 29th. According to officer LaTanya Able, the public information officer for the Memphis Police Department, investigators are working diligently to solve the case but no new information has been discovered. Yevick, a 38-year-old resident of Hot Springs, Arkansas, was found dead just before 3 p.m., lying on Gayoso Avenue between Wagner Place and Front Street. She had apparently been stabbed in the throat several times. She had with her a black travel bag containing makeup and two small plastic bags. On Tuesday, Memphis police were looking for a female suspect described as being a heavyset black woman with shoulder-length hair, standing about 57 to 59 and last seen wearing a blue shirt, blue pants, and white tennis shoes. Police were also looking for a man who may have witnessed the crime, but no description of the man was available. Anyone with information on this crime is asked to call Crime Stoppers at 529-CASH.
