A controlling lover has been jailed for at least 28 years for killing his girlfriend hours after making a new year resolution never to hurt her again.
Myles Williams, 19, of Hackney, east London, was given custody for life at the Old Bailey after being found guilty in September of murdering Kirsty Treloar, 20, and wounding her brother and sister. Miss Treloar was stabbed 29 times by Williams, just three weeks after she gave birth to their baby.
Earlier, he sent her a text at 11pm on New Year's Day saying: "Okay wer all gud now and my new yrs ressy is that i aint going to hit u again and i won't hit u 4 this yr next yr the yr after that the next yr after that."
It ended: "But I wont u to swear on (their daughter's) life u wont piss me off and do things to make me angry love you 4 eva."
Judge Nicholas Cooke told him: "Beyond a shadow of doubt, you represent an exceptional danger to any future female partners."
Judge Cooke said: "Exceptionally, this was a fatal attack in the presence of a 26-day-old child. That child has been left fatherless and motherless, and some time in her life she will discover that her father killed her mother. That baby was left covered in blood, probably her mother's - a terrible thing."
Crispin Aylett QC, prosecuting, told the trial of Williams's empty promise at New Year. He said: "This can only be described as a conditional New Year's resolution. It lasted only until the following morning."
Seven hours after sending his text, Williams received a reply at 6.30am on January 2 from Miss Treloar saying she did not want to see him. He broke into her family home in Brownlow Road, Hackney, east London, and launched the knife attack on the trainee nursery nurse.
When her brother Dean, 23, and sister Gemma, 24, tried to help they were also knifed. Kirsty Treloar was dragged into Williams's car and driven away. Her body was found behind wheelie bins near the abandoned car two miles away.
Miss Treloar's mother Pamela said in a statement that Williams had devastated a close family. She said: "Myles Williams has taken a decent, loving, close family and ripped us up. Kirsty was one of life's beautiful people. She was gentle and had a heart of gold."
