YouTuber's Pre-Recorded Livestream Exposed as Murder Alibi in Chilling Case
On a cold December evening in 2022, Natalie McNally logged onto her computer at 8:24pm, excited to watch her boyfriend's YouTube gaming marathon. The 32-year-old marketing professional, who was 15 weeks pregnant with Stephen McCullagh's child, had no idea she was about to witness a carefully constructed deception that would mask her own murder.
A Ruthlessly Constructed Alibi
McCullagh, a 36-year-old content creator with 37,000 subscribers, had told Natalie he would be hosting a six-hour live event playing Grand Theft Auto and Robot Wars. In reality, the footage had been pre-recorded four days earlier, creating what prosecutors would later call a "false alibi" for the brutal crime he was about to commit.
While Natalie watched what she believed was a live stream from her home in Silverwood Green, Lurgan, McCullagh was actually traveling to her house with murder on his mind. He had meticulously planned every detail, from his transportation to his forensic precautions.
The Brutal Attack and Aftermath
Shortly before 9pm on December 18th, McCullagh arrived at Natalie's townhouse and launched a vicious attack, beating, strangling, and stabbing her to death. He left her lifeless body lying face down in a dog bowl before changing clothes and attempting to return home.
His planning extended to chilling details during the pre-recorded stream. At the exact time he was committing murder, a promotional poster for the James Bond film "No Time to Die" flashed on screen - a cold-blooded nod to his actions that he later claimed was accidental.
The Investigation Unravels the Deception
Were it not for the painstaking work of the Police Service of Northern Ireland's cybercrime unit, McCullagh might have escaped justice. He had taken extreme care to permanently delete the pre-recorded file from his computer, but forensic examination eventually exposed the fabrication.
Investigators discovered McCullagh had researched bus and train times from his Lisburn home to Natalie's house on the night of the murder. He traveled by bus to avoid Automatic Number Plate Recognition cameras, wearing a heavy coat and face mask for concealment.
The Grieving Boyfriend Facade
Following the murder, McCullagh maintained an elaborate facade of innocence and grief. He traveled to Natalie's home the next night to "discover" her body, making an emotional 999 call to a friend while "howling" in distress.
He attended Natalie's wake on Christmas Day 2022, where her family granted him 15 minutes alone with her remains. He later provided a video montage for a rally in her honor, all while attempting to frame her ex-boyfriend for the crime.
Courtroom Revelations and Relationship Dynamics
During the trial at Belfast Crown Court, text messages revealed a complex relationship. While some messages showed affection - with Natalie writing "Totally addicted to you" - others indicated she was reconsidering the relationship.
Natalie had maintained contact with a former boyfriend, with whom she had sex in October 2022 while already pregnant with McCullagh's child. She told another contact she wouldn't break up with McCullagh before Christmas because "that would be mean," adding she would "see how I feel in the New Year."
The Conviction and Family Impact
After a four-week trial, a jury took just over two hours to unanimously convict McCullagh of murder. Trial judge Mr Justice Kinney confirmed the offense carries a mandatory life sentence, with the minimum tariff to be determined in May.
Natalie's family - parents Noel and Bernie, and brothers Declan, Niall and Brendan - described her as "the greatest joy we'll ever have." Her brother Niall called her "a precious egg," referencing her childhood diabetes diagnosis that made her particularly cherished.
A Call for Justice and Change
Outside court, Declan McNally paid tribute to his "inspirational" sister and called for action against violence toward women. "Violence against women and girls is the shame of our society and we must do everything possible to end it," he said.
The case highlights both the sophisticated methods criminals can employ and the crucial role of digital forensics in modern investigations. McCullagh's conviction brings closure to a three-year wait for justice, though no sentence can return Natalie or her unborn child - whom she planned to name Dean - to her grieving family.
