An Auckland teenager who has admitted attempting to murder his recent ex-partner did so by luring her to a meeting with a false Facebook account before stabbing her 20 times.
Micah Shannon Santos, now 19, was charged with attempting to kill his partner Crystal Angel Tupou along Anzac Ave last year.
Several pedestrians came to the then 18-year-old Tupou's aid as she lay wounded on the central Auckland street on November 22.
Santos was due to go to trial before a High Court jury later this year but changed his plea to guilty after a hearing this month, as first reported by the Herald.
Court documents released to the Herald which detailed his offending, however, remained suppressed until the gag order lapsed yesterday.
The files show Santos and Tupou had been in a relationship for eight to nine months after meeting at a course that they were both attending on Anzac Ave.
Their relationship, however, was characterised by a series of breakups and reconciliations during which Santos would regularly accuse Tupou of having relationships with other people.
On a Saturday evening last November, Santos began to grow angry when Tupou posted a series of Snapchat stories of her with other men, court documents read.
The following day, November 18, Santos attempted to contact Tupou on Facebook but she told him she wanted to break up, and blocked him from contacting her.
On the same day, Santos also received a Snapchat picture which appeared to show Tupou in a compromising position with another man.
This further angered Santos who began to contemplate harming Tupou.
On the Monday, Tupou again spoke to Santos - this time on the phone - and reiterated that she no longer wanted to be with him.
Santos, however, began scheming.
He decided to create a false Facebook identity - posing as a "Sarah Hussein" - and suggested "Sarah" was a friend of Santos.
He asked Tupou to meet with Sarah for lunch and talk.
Over the course of the morning of November 22, Santos resolved to kill Tupou, court documents read. He went to the kitchen and armed himself with two knives, one of which was a long-bladed carving knife which he placed in a Louis Vuitton bag.
Prior to leaving his house, Santos - as Sarah - contacted Tupou again and arranged to meet her at a carpark on Anzac Ave at 1pm.
After arriving, he waited inside the parking building for 15 minutes but after Tupou failed to show walked down the hill to Britomart Train Station to look for her.
He was unable to find her, so decided to catch the train home.
While preparing to catch a second train back to Sunnyvale, however, Sarah received a message from Tupou confirming their meeting on Anzac Ave.
Santos immediately made his way to the carpark on Anzac Ave.
On arrival he approached Tupou and a heated argument ensued.
Santos told her he wished to kill her before putting his hands around her throat and squeezing tightly, court documents read.
