Gareeca Gordon, pictured left, murdered Phoenix Netts (right), also 28, at the property where they both lived in Birmingham on April 16 last year.
Gordon, a Jamaican national stabbed Miss Netts four times, causing fatal injuries, before cutting her body into six parts with a circular saw she bought on Gumtree for £45.
Gordon admitted to killing Ms. Netts after being accused of stabbing the former student to death at the HMO property the pair shared in Lozells, West Birmingham, on 16 April.
The killer pleaded guilty to the murder a few days before she was due to stand trial.
Prosecutor Andrew Smith QC said the victim had told a friend in February that Gordon had “demanded sex with her” and became “aggressive” when she refused.
On 7 April, she texted a friend: “There’s a girl here who keeps asking me to be sexual. I think I’m going to move back to London. It’s scaring me lol.”
Bristol Crown Court heard that Gordon called the Samaritans on 11 April and appeared “tipsy”.
“The clear focus of the call was Ms Gordon describing that she liked another woman and wanting to have sex with her,” Mr Smith said.
“At one stage Ms Gordon said either that her loins were warming up or were hot.”
Ms Netts’ last-known contact was a phone call with a friend in the early hours of 16 April.
Internet searches including “how to fix punctured lung”, “internal bleeding” and “can someone recover from getting stabbed” were made on her phone between 1.04pm and 3.07pm, the court heard.
The victim had been stabbed four times in the front of her torso but according to a post-mortem she would have lived if she had got swift medical help.
Another woman living in the shared accommodation heard drilling and banging noises, as well as shouts of “help me, help me”, Mr Smith told the court.
She said Gordon had gone to ‘considerable efforts’ to dispose of the remains of Ms. Netts and to pretend she was still alive in ‘cold and calculated’ messages to her friends and family.
