Steven Mathieson, 38, was high on cocaine when he stabbed 23-year old Luciana Maurer to death at his home in Glasgow, Scotland, then held two more women at knifepoint and raped them.
The two managed to escape when he was distracted, reports the Falkirk Herald. Realizing his predicament, Mathieson called police and told them that "I've been high on drugs and I've killed a prostitute," and surrendered upon their arrival.
The three victims were sex workers who had been called to the house by Mathieson after his partner went for a night out with colleagues.
During his attack on Maurer, Mathieson texted his partner with "Sorry xx," according to the Daily Mirror.
At his sentencing, however, his advocate offered some unusual thoughts in mitigation. The BBC:
Prior to sentencing, defence advocate Donald Findlay QC told the High Court in Livingston that Mathieson was a "slightly boring man" with a "slightly boring life", who was "not in his right mind" due to his use of cocaine.
Mr Findlay said: "Sending for three prostitutes to come to his home while his young son is asleep in a bedroom and his wife could come home at any time is an insane thing to do.
"He booked one and then for good measure he booked two more and that in my submission reinforces the whole madness of this episode.
"I think it's fair to say that on any view this is one of the most extraordinary cases I've ever encountered."
The judge was unmoved by the suggestion of cocaine use and personal boringness as mitigating factors, and sentenced Mathieson to life imprisonment, with no chance of parole for 22 years.
