Michaela Dunn, 24, was found dead at 3:15 pm in an apartment on Clarence Street, just over an hour after Ney allegedly stabbed Linda Bo, 41, in the back

The van Mert Ney family was afraid that he would commit suicide a few days before he allegedly killed a woman and wanted to commit a nasty disaster, but the police could not find him because of a monumental administrative blunder.

The accused attacker, 20, stormed through the CBD on Tuesday afternoon with a large kitchen knife waving in blood.

Michaela Dunn, 24, was then found dead at 3:15 p.m. in an apartment on Clarence Street, just over an hour after Ney allegedly stabbed Linda Bo, 41.

Although many were shocked by the alleged actions of the 20-year-old, those around Ney say that his & # 39; steep descent into madness & # 39; it became so clear in the seven days prior to the attack that the police tried to track him down.

But when the police searched for him, they did not know that Ney lived in government emergency shelters and could easily have been located.

The Australian reported that it all started on August 7, when Ney & # 39; s mother and sister called the police after an alleged intense confrontation at their parental home in Marayong, western Sydney.

He was first seen on CCTV surveillance at the emergency department of Blacktown Hospital after an overdose of prescription drugs on August 7.

Melinda Ettery, a first-aid patient that evening, told the Seven Network that it was clear that he was agitated.

& # 39; He was loud and boisterous and rude to nurses and doctors, & # 39; she said.

Hours later he left the hospital and returned to his parental home where he had a cruel confrontation with his sister, Yazel Ney.

The 20-year-old allegedly slapped his sister in the face and smothered her before she and her mother contacted the police.

Ney managed to escape before the police arrived, so they went hunting for a week to find him because they feared he would commit suicide.

The sister, who refused to be called, said she wanted her brother to suffer for what he had done, and to be placed in the worst (most serious) mental health institution to prevent him from hurting anyone

Without the knowledge of the police, he went to a local doctor on August 9 and said he had suicidal thoughts, so he worried the doctor so much that he also contacted officers.

According to police, Ney escaped again before being seen again at Blacktown Hospital that same day, but only for a few hours.

In the three days before the disaster in Sydney, Ney lived in emergency homes in a community house in Blacktown.

A police source told the Australian that they only found out after Ney caused chaos in the city that he was in emergency shelter.

& # 39; The police were looking for him and we were worried, but it remains a mystery why we didn't get a call, & # 39; said the source.

According to The Daily Telegraph, it was Communities and Justice's fault because they had no contact with police or health authorities about the potential danger of Ney.

Sickening moment Sydney knifeman casually takes a SELFIE after leaving the apartment where he allegedly killed a woman, 24, by cutting her throat – before he went on a six-minute disaster in the CBD

The man accused of making a stabbing by Sydney & # 39; s CBD casually took a selfie on a street just after he cut the throat of a 24-year-old woman.

Michaela Dunn was found dead on Tuesday in a Clarence Street unit nearly two hours after Mert Ney, 20, was first seen on camera surveillance at 1:30 PM.

New images obtained by Channel Seven appeared from Ney, who wandered through an alley just before 2 p.m., then paused, and then seemed to hold a phone in front of him.

After apparently taking a selfie, he then ran down the deserted alley to neighboring Clarence Street – where his outburst of the city began.

The images appeared after Ney & 24's alleged victim was identified as Mrs. Dunn, who went to Rosebank College, a Catholic school in the interior of Sydney and studied at the University of Notre Dame.

Later a sex worker was found with her throat cut in her central city apartment (in the photo, her neighbor's apartment)

Mrs. Dunn was then found dead in the CBD apartment, with the police because she said she was a sex worker and Ney was her client earlier in the day.

Detectives believe he traveled downtown on Tuesday with the intention of killing and being killed by the gun of an agent.

It is assumed that the appointment was made at 1.30 pm, but Ney spent only 20 minutes in the Clarence Street apartment.

Ney was seen on camera footage that left the building at 1.50 p.m. and the police claimed he had killed her before he fled the block in a blood-soaked sweater and caused chaos through the streets of Sydney.

Researchers believe Ney and Mrs. Dunn had not had any previous contact before Tuesday, but are looking through their phone details to determine the nature of their relationship.

& # 39; Our early investigations showed that the accused never intended to pay the victim for services for which he had made arrangements & # 39 ;, one investigator said.

& # 39; Similarly, it seems clear that he wanted to be killed by the police. & # 39;

Teen homeless couple Courtney Ridgeway, 19, and Nathan Tgiy, 16, described Ney as & # 39; agitated & # 39; and & # 39; scary & # 39; when they stayed in a room next to his in the emergency shelter.

They heard 20-year-old terrorism discussing on his phone information he had on a USB stick.

& # 39; He was talking about terrorism and Allahu Akbar – he loved that word, he said it often & # 39 ;, Ridgeway said 9News.

& # 39; I think he planned what he was going to do the next day.

& # 39; He just said he had a USB and did some research, and studied what it said. & # 39;

Ney was knocked down by heroic bystanders after stabbing 41-year-old Linda Bo in broad daylight.

Shortly thereafter, Mrs. Dunn was found dead in the apartment.

Photos shared on social media showed Ms. Dunn through Sri Lanka and the US last year, as well as previously on vacation in Europe.

Her mother told Nine News that Mrs. Dunn was a & # 39; beautiful, loving woman who had studied at the university and traveled extensively & # 39 ;. She also said that the young woman & # 39; very much loved & # 39; used to be.

& # 39; Although her family appreciates the support of the community, they have asked for privacy in this difficult time & # 39 ;, read a statement from the police.

& # 39; The investigation into the circumstances surrounding the Michaela murder is led by investigators from the Murder Team under Strike Force Lalchere. & # 39;

Ney's sister, who did not want to be named, apologized to the family of his alleged victim and said: "I am sorry a million times … I am really sorry for the victim & # 39;"

Mrs. Ney said her brother had a & # 39; steep descent into insanity & # 39; and that she wanted him to suffer & # 39; and was severely punished by the law for what he allegedly did.

& # 39; I want him to suffer. I just want them to place him in the worst psychiatric institution where it is like a prison, & she said.

The woman said she felt shocked, angry, disgusted – I hate my last name & # 39; in remarkably candid comments to the parental home in western Sydney.

& # 39; Above all, I just want to say sorry to the victims, & # 39; said the tearing sister. & # 39; She (the killed 24-year-old who was found dead in a unit) was like, younger than me.

& # 39; She could have gone out in a few hours to go shopping with her mother, dine with her boyfriend, her girlfriends and s *** s. She can't do that now, can she? & # 39;

& # 39; All the words I could say will never bring her back … I'm really sorry, she was so defenseless and so. & # 39;
