A teenager has been sentenced to life in prison for killing his girlfriend just hours after making a New Year’s resolution never to hurt her again.
Myles Williams, 19, was found guilty in September of murdering Kirsty Treloar, 20, and wounding her brother and sister.
He stabbed Miss Treloar 29 times in front of their 26-day-old daughter on January 2.
Williams will have to serve at least 28 years.
"Beyond a shadow of doubt, you represent an exceptional danger to any future female partners," Judge Nicholas Cooke told him.
"That child has been left fatherless and motherless, and some time in her life she will discover that her father killed her mother."
At 11pm on New Year's Day, Williams sent Miss Treloar a text message 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."
Williams received a reply from Miss Treloar at 6.30am on January 2, in which she said she did not want to see him.
He broke into her family home in Hackney, east London, and launched the knife attack on the woman, stabbing her in the chest.
When Miss Treloar's brother and sister tried to stop him, they were also knifed, according to the prosecutor in the case, Crispin Aylett QC.
The woman's body was then dragged into Williams's car, and was later found near the abandoned vehicle a few miles away.
Miss Treloar, a trainee nursery nurse, had begun a relationship with Williams a year earlier.
Her mother, Pamela, said in a statement: "Myles Williams has taken a decent, loving, close family and ripped us up."
