A murder investigation is under way into Lisa Thompson's death in Sandyhill Gardens in Ballymun.
She was 51 years old and had two young children,
Lisa was not involved in crime, and no one has been arrested so far.
John Hand, the chief reporter with the Irish Daily Mirror, says she may have been killed by someone she knew.
"It was a very violent death which would indicate it could possibly be someone she knew."
Meanwhile, local councillor Keith Connolly says the area's stunned by the news.
He said Lisa was mother to two children in their early teens - he described the community as "devastated".
