A Canadian man allegedly told police officers investigating his ex-wife's disappearance that he was 'the reason you're here' as he emerged from the woods, near where the woman's body would later be found.

Vitali Stefanski is now on trial facing second-degree murder charges at British Columbia Supreme Court in connection with his ex-wife Tatjana Stefanski's brutal stabbing death.

Her son last saw the 44-year-old mother-of-two on April 13, 2024 as she was walking across her driveway of their home toward her ex-husband, who showed up to her house that morning, prosecutors claim.

As police then investigated her disappearance the next day and located a car Tatjana was believed to have entered, they found Vitali, shoeless, on a remote logging road near Mabel Lake, Crown Prosecutor Rigel Tessman said as the trial got underway on Tuesday, Castanet reports.

'The man's first words were: "That is my car - I am the reason you're here,"' Tessman said in his opening statement.

When two Mounties then asked Vitali where his ex-wife was, he allegedly admitted to murdering her.

'[The constable] will tell you he remembers the man saying, "Yes, she is dead. Yes, I have killed her,"' Tessman told jurors.

Tatjana's stabbed body was later located just about six kilometers - or about three and a half miles - away

'It was in that moment that the police operation shifted from a missing persons investigation to an arrest for murder,' the prosecutor said, according to the Winnipeg Free Press.  

He noted that a pathologist will testify during the five-week-long trial that Tatjana died after suffering multiple stab wounds, including one to the chest and six to her rib cage that pierced her heart and lung.

She also suffered 'sharp force wounds' to her legs, arms and hands, which Tessman said an expert would testify were consistent with defensive wounds.

According to the prosecutor, Vitali had arrived at his ex-wife's home on April 13, 2024, when Tatjana confronted him on her driveway.

Grainy surveillance footage from a neighboring storage unit facility then showed two figures getting into a black car and leaving the property before Vitali and Tatjana's daughter reported her missing.

Her father later allegedly told her and her brother, ages nine and 16, that morning that they were 'alone in the world now.'

As the investigation into Tatjana's disappearance then got underway, police received a tip about a black Audi matching the description of the suspect's car driving up a service road.

When authorities then arrived at the scene, they found the vehicle abandoned - with blood on the driver, passenger and back seats, which was later confirmed to be Tatjana's.

At that point, officers broke into the car to check the trunk - but found no one inside. 

Police then searched the area and kept watch over the vehicle overnight, but found nothing. The next morning, Tessman said, Mounties decided to tow the vehicle, at which point Vitali emerged from the woods. 

The suspect sat quietly in court on Tuesday as Tessman laid out the prosecution's argument.

He wore a dark navy suit with a white collared shirt as he sat behind a Plexiglass barrier, and he spoke up only to say he was 'not guilty' when he was arraigned in front of the jury.  

The defense has not yet presented its arguments. 

Tatjana's brutal murder has rocked the tight-knit Lumby community, which has rallied around Tatjana and Vitali's two children, as well as her partner at the time, Jason Gaudreault, according to Global News.

Gaudreault is now watching over the two children, and he has said both children are expected to testify during the weeks-long trial.

To support the family during that time, family friend Jen de Bourcier created an online fundraiser for travel expenses, lost wages, emotional support and to help Gaudreault continue providing stability and care for the children.

'Tatjana was the devoted mother of two children, both of whom continue to live with the loss of their mother every day,' the fundraiser says. 

'Jason has guardianship of the children, and together they have been navigating an unimaginable path forward.

'The past two years since Tatjana's murder have been difficult in ways only those affected by violent crime can truly understand,' it continues. 

'Grief, trauma, uncertainty and the emotional weight of the justice process have touched every aspect of their lives.

'Despite everything, Jason has worked tirelessly to rebuild stability for the children and create a future for their family,' the fundraiser notes.

As of Tuesday evening, it had garnered $1,070 CAD for the family.
