Billy Edwin Reid (born 1959) is an American murderer and a suspect in the murders of at least 17 women in Denver, Colorado between 1975 and 1995. The murders were grouped together only in 2008, before then they were thought to have been committed by different perpetrators. In 2005, based upon results from DNA profiling, Reid was tied to the 1989 murders of Lannell Williams and Lisa Kelly, and authorities suspect him in more.
