A British mother stabbed her daughters to death while they slept in order to "wreak havoc" on her ex-husband, a court has heard.
Rekha Kumari-Baker took her daughters Davina, 16, and Jasmine, 13, on a shopping trip to "soften up" the girls before the night-time attack, prosecutors at Cambridge Crown Court claimed.
Ms Kumari-Baker allegedly planned to murder the children after a previous day of shopping on June 11, 2007 but had a change of heart when her eldest sent her a text message from her nearby bedroom thanking her for the excursion.
But during a second consecutive day buying gifts, the 41-year-old hotel worker allegedly crept into each girl's bedroom in her pyjamas and killed them in a "frenzied" attack with a knife she had bought with them at a supermarket.
Prosecutors said that 16-year-old Davina was stabbed 39 times as she tried to resist at about 2.30am on June 13.
Ms Kumari-Baker then allegedly entered her youngest daughter's room and killed her in the same way.
She then got dressed and twice climbed into her car before phoning a police officer friend about four hours later.
"I've done something terrible Natalie," she said on special police constable Natalie Barford's voicemail.
"Please call me."
Ms Kumari-Baker has denied the murders, claiming she was suffering from "severe abnormality of the mind", the Daily Mail reports.
She may face a lesser charge of manslaughter if jurors accepted her defence.
