A woman who accompanied fallen soccer star Kerem Bulut on a violent robbery died of a drug overdose last year after taking heroin she believed was cocaine.
Angel Mounce-Stephens, 43, was found dead at her Newtown home in Sydney’s inner-west on August 30, having long struggled with substance abuse.
The body of her friend, 30-year-old social media influencer Dunka Raymond Caldwell, known on TikTok as ‘Humdinger’, was located at his Glebe home hours earlier.
It is believed the pair had taken the same batch of contaminated cocaine.
Mounce-Stephens, also known as Angela Yazgan, had been in a relationship with Bulut two years ago when he staged a robbery in which she took part.
She had convictions for drug supply and possession, as well as theft, shoplifting, fraud and dealing with the proceeds of crime, and had previously been ordered to undertake rehabilitation.
Mounce-Stephens was sentenced over her role in the crime she committed with Bulut three weeks before she died.
Bulut, who had once been tipped for international footballing greatness, pleaded guilty in June to demanding property by force while in company and will face a sentencing hearing later this month.

The Daily Mail can now reveal the events which led up to that offence, which have kept the 33-year-old behind bars for almost two years.
Bulut, whose sporting career fell apart after he was caught using cocaine in 2018, subsequently developed a meth addiction and his life went off the rails.
The onetime A-League cult hero with Western Sydney Wanderers was 31 and living in a notorious inner-city public housing block at the time of his latest crime.
His victim, whom Bulut had never met, was a 37-year-old man from Bathurst, in the NSW central west, who was staying in Sydney with friends in late August 2023.
On August 31, Bulut sent a series of texts to a friend who knew the victim, calling the victim by his first name.
In one message sent about 7.30pm, Bulut referred to former AFL player and commentator Rex Hunt, who is perhaps just as well-known for his fishing television shows.
‘Brother, send him girls photos, send him girls,’ the text began, according to a statement of facts tendered in court.
‘Go on Instagram, just pick any girl, model and that, say it’s the girls, this that, hook line and sinker brother, Rex Hunt the motherf***er, then we put him in the fishing net.’

About an hour later, Bulut’s friend contacted the victim via the encrypted messaging app Signal and asked if he wanted to ‘party with some girls at an Airbnb’ in Sydney’s east.
The friend sent the victim images of two women with the message: ‘The girls found [an] Airbnb in Coogee for $1000, and they are adamant they want it.’
According to the statement of facts, the victim agreed and about 11.30pm drove a rental car to a block of units in Bundock Street, South Coogee.
There, Bulut’s friend was waiting with two women, one of whom was Mounce-Stephens, according to the court documents.
All four went up to a unit where Bulut confronted the victim in the loungeroom.
‘Sit down, we need to have a chat,’ Bulut told the victim after the friend and two women had left the room.
When the victim said, ‘I have been driving for a bit, I’m good,’ Bulut responded, ‘I have heard you’ve been talking s***’ and confronted him about his previous contact with Mounce-Stephens.
Bulut then used a closed fist to strike the victim to the side of his mouth, causing him to bleed, according to the court documents.
‘Sit the f*** down,’ Bulut said, before another man of large stature and ‘Islander heritage’ joined him in the loungeroom.

Kerem Bulut appeared to have the footballing world at his nimble feet until he was caught using cocaine in 2018 – but three years after vowing to get himself off meth, he’s still behind bars
‘You’ve been talking s***, saying I’m a dog,’ Bulut told the victim, punching him in the side of the head as he tried to protect himself.
‘You’re going to give me money, everything you’ve got on you,’ Bulut warned.
The victim replied: ‘Come on man, I haven’t done anything wrong.’
Bulut asked the victim to hand over his phone and unlock it. He then used a banking app to transfer $600 belonging to Mounce-Stephens, court documents revealed.
The victim denied carrying a wallet and tried to move towards the door but the Islander winded him with a strike to the torso.
Bulut handed the victim a tissue to wipe blood from his lip, and the victim said he would try to get more money.
There was an argument over the keys to the rental car until the victim surrendered them. The Islander and Mounce-Stephens then went outside to the vehicle.
Bulut and the victim stayed upstairs and had further discussions before going down to the car, which the Islander plundered of goods.

Before his downfall Bulut had been considered a potential successor to Socceroos legend Tim Cahill, filling the goal-scoring gap left in the national team by his retirement
The Islander left the scene after stealing the victim’s Louis Vuitton wallet, which contained $1,500 in cash, as well as his sunglasses, Bluetooth speaker and a bottle of perfume.
Bulut took from the boot a G-Star hooded jumper, another Fendi jumper, a tracksuit, two T-shirts, three pairs of underwear, two pairs of socks and a pair of slides.
CCTV captured Bulut wearing the victim’s G-Star top near his home in Belvoir Street, Surry Hills at about 3am, and the Fendi jumper nearly an hour later.
Bulut was in possession of the Louis Vuitton wallet when stopped by police in nearby Devonshire Street four days later on September 5. He was arrested on September 11 at Maroubra police station while reporting for bail on an unrelated matter.
Bulut pleaded guilty to demanding property by force while in company at Downing Centre District Court on June 12 and will face a sentencing hearing on August 21.
He will also face sentencing for an offence of larceny, while the charge of robbery in company will not proceed on the indictment.
Mounce-Stephens was originally charged with robbery in company but that count was withdrawn at Downing Centre Local Court on August 8 last year.
On the same day she pleaded guilty to larceny of goods worth more than $5,000 but less than $15,000 and was placed on a nine-month intensive correction order.

Bulut was remanded in custody at the time of his arrest until bail was granted under extremely strict conditions in October 2024. His bail was revoked a month later.
Since 2020, Bulut has been prosecuted for a string of offences under the names Kerem Bulut, Karem Bulut, Kerim Bulut, Keiran Bulut and Kerim Bulet.
His September 2023 arrest came 15 months after Bulut had begged a magistrate for help overcoming an ice addiction he said began in jail.
Before his downfall, Bulut had been considered a potential successor to Socceroos legends Tim Cahill or Harry Kewell who would ultimately fill the goal-scoring gap left in the national team by their retirement.
The gun striker played for the Australian U17, U20 and U23 sides before securing European contracts with clubs in Germany, Greece and Turkey, as well as his two stints with the Wanderers.
But Bulut’s life began to publicly unravel in October 2018 when he was banned from football for four years after being caught using cocaine while playing professionally in Turkey.
Following the deaths of Mounce-Stephens and Caldwell, police launched an investigation under Strike Force Chatton.
‘Police are awaiting the results of a post-mortem examination to determine the exact cause of their deaths,’ a NSW Police spokesman said at the time.
‘As investigations continue, anyone with information is asked to contact Crime Stoppers.’
