Juana Dayanara Barraza Samperio (born 27 December 1957) is a Mexican convicted serial killer and former professional wrestler known as "La Mataviejitas" ("The Old Lady Killer"). She was convicted of the murders of 16 elderly women and sentenced to 759 years in prison.
The killings attributed to "La Mataviejitas" have been variously dated: some accounts place the first murders in the late 1990s, while at least one source cites a specific killing on 17 November 2003. Authorities and the press have estimated the total number of victims at between 42 and 48 deaths. After Barraza's arrest, officials officially closed the Mataviejitas investigation despite more than 30 unresolved cases.
