A vile killer who butchered a teenage mum and dumped her body parts died of natural causes after contracting sepsis in prison, an investigation into his death has found.
Evil Michael McArthur was jailed in 2004 at the High Court in Edinburgh for murdering and then dismembering the body of 19-year-old Amy Anderson in 2002.
The 76-year-old was serving a life sentence at HMP Dumfries when he passed away on April 11 last year.
