A young woman whose online post made her new relationship ‘Instagram official’ was killed hours later by her deranged stalker.
Celeste Manno was stabbed 23 times to death in her own bed by Luay Nader Sako on November 16, 2020 after he became enraged upon seeing her hand-in-hand with her new boyfriend Chris Ridsdale.
She was just a few days short of her 24th birthday.
Sako, 39, of Roxburgh Park, appeared in the Supreme Court of Victoria on Monday where he is representing himself in a pre-sentence hearing.
He pleaded guilty to her murder in April after trying to contest the charges for years.

The court heard Sako had bombarded Ms Manno with endless messages professing his love for her in the year before he ended her life.
Sako had worked with her briefly at Serco’s call centre in South Morang – she was a team leader – before he was sacked.
Ms Manno had shown kindness to Sako on his final day, walking him to his car and wishing him well before he unexpectedly kissed her on the cheek.
Sako murdered Ms Manno inside her family home in Mernda, in Melbourne’s northeast, at 4.10am.
He smashed his way into her bedroom with a hammer and attacked her in her bed.
The whole ugly incident took just two-and-a-half minutes, with Sako then driving directly to a local police station to admit what he had done.
CCTV footage captured from cameras across the road showed the moment Sako fled the Manno property after committing his heinous crime.
Sako had already been charged for stalking and harassing Ms Manno and had been subject to a intervention order supposedly protecting his victim at the time of her murder.
Both Ms Manno and her mother had pleaded with Sako for him to leave her alone in the months and weeks before he struck.
The court heard Sako peppered her with creepy, lewd and menacing messages via Instagram through various accounts, concluding with a three-and-a-half-page rant in which he demanded she withdraw her police complaints against him.
Sako’s deranged messages to Celeste Manno
‘I’m sorry but I can’t stop thinking about you. I have never felt like this about anybody in my entire life, it’s bordering along a OCD. I’m totally infatuated with you, captivated and fascinated by you. You’re all I think about,’ he wrote.
‘After leaving you my productivity and my personal life in my new job has been impacted. This obsession with you, which is a crush, is an addictive and destructive feeling that is interfering with my ability to concentrate, deal with others and go about my daily routine.’
Sako begged Ms Manno ‘put an end to his suffering’ by being direct with him in her feelings towards him.
His terrified victim politely responded to Sako in the hope he would leave her alone.
‘Hi Luay, those are really sweet words and I appreciate you saying all of that to me. I’m a bit surprised to read this all as it is new to me.
‘As much as I appreciate this, I only feel in a professional way towards you and I wish you all of the best in your new job and journey.’
But her gentle tone only seemed to make things worse, with Sako pledging to give his life just to be with her.
‘I’m so infatuated with you that it’s now become unhealthy. I know my words don’t help me … I’m sorry for coming on strong Celeste. I’m just another rival for your affection,’ Sako wrote.
When Ms Manno pleaded with Sako to stop messaging her, Sako became enraged.
‘I’m truly sorry for making you feel uncomfortable. I really just wanted to speak with you and I honestly thought you were ignoring me,’ Sako responded.
‘My impression of you has changed. You’re no different to the majority of women. I’ll remember you and this lesson for all life and I will devote every ounce of energy I have to climbing up and proving to the world that I’m somebody.
‘That is my promise to you and my final contact with you.’

As the messages continued, Ms Manno contacted Sako directly telling him they were going to the police to report his harassment.
While Sako stopped briefly, the respite was short lived, with Victoria’s Covid-19 lockdowns seemingly fueling his obsession, the court heard.
Sako was later seen lurking around Ms Manno’s vehicle outside her workplace, with a court issuing an interim intervention order against Sako on July 3 that year, the court heard.
The soon-to-be killer refused to accept the order, listing the matter for a contested hearing in March the following year.
Detectives arrested Sako in August, charging him with breaches of the order before releasing him back into the community.
With Sako back on the loose, Ms Manno confided in her boss that she believed her days were numbered.
‘He’s really going to kill me,’ Celeste confided in her colleague.
Hours after going public with her secret relationship to Mr Ridsdale she would be dead.
The court heard Sako stabbed Celeste to death in a wild frenzy, with defensive wounds found on her arms and hands as she fought for her life.
When he was done he told cops where they could find Celeste’s body.
‘She’s dead. Go have a look,’ he said. ‘You know what happened. It’s your fault.’

In a further cruel blow to the friends and family, Sako contested the number of times he stabbed his victim.
The move required a forensic expert to give graphic evidence in court of the way Ms Manno was killed.
Celeste’s family has been forced to endure watching Sako cross examine the expert on the various stab wounds he inflicted on their loved one.
Dressed in grey prison garb and wearing dark-rimmed glasses, the twisted killer did his best impersonation of a lawyer as he questioned the doctor’s findings.
Sako has taken issue with the doctor’s assessment of the injuries, claiming many of the wounds on Celeste’s body were caused by broken glass.
Sako sacked his barrister Tim Marsh on the eve of the trial over the issue, maintaining he only stabbed Celeste twice.
Mr Marsh told Justice Jane Dixon on Monday he was happy to assist in Sako’s plea hearing as a ‘friend of the court’ but was no longer acting for the cold-blooded killer.
Sako had originally been represented by high profile criminal barrister Sam Norton, of the firm Stary Norton Halphen.
Mr Norton was forced to dump Sako after he ignored his advice to plead guilty to the crimes when his mental impairment defence was deemed no longer viable.
Sako attempted to change his guilty plea after employing Mr Marsh last year.
The road to bring Sako to justice has been long, with the alleged killer appearing in court repeatedly over the years in an effort to convince forensic doctors he had been insane when he killed his victim.
In March 2022, the court heard while Dr Andrew Carroll – on behalf of Sako – argued the killer was too mentally unwell to properly direct his lawyers, Dr Clare McInerney – for the prosecution – believed that prognosis could be cured.
Crown prosecutor Patrick Bourke asked Sako be assessed yet again – this time by forensic psychologist Professor James Ogloff.
A plan to put Sako to trial over his mental impairment was abandoned in February when the court heard the once conflicted doctors had come to the conclusion that Sako indeed knew what he was doing at the time of the murder and was well enough to stand trial.

But even then, Sako sought to delay his May 16 murder trial long enough to convince doctors he was again too sick to stand trial.
The court heard Sako insisted on remaining locked away from other inmates in an isolation unit where he refused to take medications.
Sako had repeatedly threatened suicide if he were to be moved out of his isolation cell, where he spends up to 23-hours a day in lockdown.
Ms Manno’s friends and family are expected to read their victim impact statements to the court on Monday afternoon.
The hearing continues.
