In a powerful victim impact statement, Courtney's mum Samantha Mitchell, said: "The day my little girl died my whole world shattered into a million pieces - no parent should have to bury their child.
Courtney Mitchell, 26, was out with two friends when Logan Burnett, 27, began storming over to them armed with two knives.
At the time of the murder, Burnett was on bail after he went to Courtney's new home and ransacked it - ripping radiators off the wall and causing extensive water damage.
Sentencing, Judge Martyn Levett described the horror as a "personal execution" and said Burnett had "hunted [Courtney] down as if she was your quarry".
Burnett, who had was banned from communicating with Courtney or visiting her address, also bragged about how murdering her would make him "Facebook and news famous".
