Dateline: Running Man jumps straight into the chaos of one winter morning in Ontario when a quiet ski town woke up to a mystery that made zero sense at first. A burned SUV. Human remains inside. A family suddenly torn apart. And a husband whose story began falling apart faster than anyone expected.
So how did detectives actually catch him? The early clues, the son’s heartbreaking account, and a trail of tiny details built the case. In simple words, investigators connected James Schwalm to Ashley’s murder by piecing together his shifting story, physical evidence at the scene of the crime, and major inconsistencies that came to light during interviews.
Below is the full breakdown of how Dateline shows the hunt for answers and how the truth finally surfaced.
How a burned SUV in the snow made detectives look at everything twice
When Dateline opens the episode, the story instantly feels eerie. It was still dark outside on January 26, 2023 when a driver spotted an SUV in a ditch near The Blue Mountains. The car was engulfed in flames. Snow all around. No tracks except a single line of footprints heading back toward the road.
That sight was already weird on its own. But things became even stranger once investigators realized the SUV belonged to firefighter James Schwalm.

According to Dateline, the Ontario Provincial Police officers walked around the scorched car and found human remains in the passenger seat. The fire was so intense that they needed dental records to figure out whose body it was. A lighter was found nearby with the initials JWS. That was the first tiny detail detectives tucked into their minds.
Inside the episode, correspondent Andrea Canning explains how the entire community froze when word spread. Canning grew up in the region, worked in local news there, and said it felt surreal to return for a case this dark.
She told CTV News videographer Mike Arsalides, who appears in Dateline, that people kept calling her saying “There’s been a murder in Collingwood,” because no one expected something like this to happen in their own backyard.
The investigation sped up right after the coroner confirmed the victim was the 40-year-old mother of two, Ashley Schwalm. Her injuries did not match a car crash. The autopsy confirmed strangulation. Detectives now had a homicide case on their hands. The husband’s car, the lighter with his initials, and the footprints leading away from the scene began to feel a lot less random.
But Dateline shows that the investigation did not stop at the SUV. Detectives went straight to James. This was only hours after the discovery. He told them Ashley had gone for a morning hike at a nearby ski club. He even showed text messages he claimed came from her. On the surface, he acted calm. But the problem was that nothing else around him seemed to match the version he was giving.
The first crack in his story came from the couple’s nine year old son. In one of the toughest parts of the episode, Dateline explains how the child told officers he heard a fight early that morning. Ashley asked him for her phone because she wanted to call the police.
Then James told him to go back to his room. Later, around three in the morning, the boy saw his dad with a coat on. James said he was taking the dog out for a walk. But the dog was still at home.
That small detail became a massive clue. Investigators now knew something terrible may have happened before sunrise. This was the starting point where everything began to turn toward James.
When detectives followed the timeline, James' story began falling apart piece by piece
Dateline spends a big chunk showing how investigators built a solid timeline. They kept checking James’ version of events and quickly realized things were not matching up. Every small moment in the early morning hours mattered.

Detectives asked themselves simple questions. When exactly did Ashley leave? Did she really go hiking? Did the neighbors see anything? Was she in contact with anyone? And did the texts in James’ phone truly come from her? They also looked carefully at the family’s relationship. That is when the affair details surfaced. These pieces were not gossip to detectives. They were motives.
Official reports included in the episode show Ashley had an affair with her boss in early 2022. She later left that job after the truth came out. She and James tried to work on their marriage. But by the end of 2022 both of them were telling loved ones they were unsure their relationship would survive.
But what Dateline then revealed is that James was also involved with someone else. He was secretly seeing the ex-wife of the man Ashley had had an affair with. Their relationship became serious in mid January 2023. He confessed deep feelings to her and she told investigators later that she felt the same.
Police checked James’ online searches. They found searches about alimony, searches about deleting search history, and searches about fire related topics. All very close to the date of the murder.
One of the most chilling details in the Dateline episode is the life insurance policies. Ashley had two. One was worth 250,000 dollars. The other was valued at one million dollars. And James was the beneficiary of the second one.
On top of his suspicious movements, the confusing text messages, the son’s statements, and the insurance connection, detectives also learned about surveillance footage from the area where the SUV was found.
This was exactly why the timeline mattered so much. Investigators believed James strangled Ashley at home during the early morning fight, changed her clothes into hiking gear, placed her body in the car, and drove to the site that became the scene of his crime. After setting the car on fire, he walked back toward the main road. Those footprints were now a huge clue that pointed directly at him.
Everything investigators found stacked up slowly, moment by moment. Each new detail and clue broke apart his original story until it simply could not hold together anymore.
What happened once police confronted the truth and the investigation closed in
By the time Dateline gets to this part of the episode, you can feel how close police were to moving in on James. It was only a week after Ashley was found when investigators finally arrested James on February 3, 2023. They charged him with second degree murder and with indignity to a dead body. Later, the murder charge was upgraded to first degree.

The investigators believed he carefully staged the scene to make it look like an accident. Court records shown by Dateline reveal he later admitted that he had burned Ashley’s body after pouring gasoline and setting the SUV on fire.
The legal process took time. Interviews, the collection and review of evidence and witness testimonies stretched for over two months. When the case reached court, journalists like Mike Arsalides, who appears in the episode, described how intense the atmosphere was and how every detail shocked the community again and again.
One of the biggest emotional moments covered in the episode is James’ own courtroom statement. In November 2024 he said,
“I never thought I saw myself capable of these horrendous actions...I despise my actions and am haunted they continue to hurt the people I love and care for the most.”
He called his actions terrible and awful and said he deserved to be where he was.
The judge did not hold back either. During sentencing, the court described James’ actions as a betrayal of trust that completely went against everything expected from a firefighter. There were also concerns about how calculated the staging was. The searches about fire techniques, divorce costs, and wiping digital history all made the situation look deliberate.
In June 2024 James pleaded guilty to second degree murder. In early 2025 the judge sentenced him to life in prison with no chance of parole for twenty years. There is also a strict order that he cannot contact his children until they turn eighteen.
Dateline highlights how the wider community reacted too. Ashley’s family began using her story to raise awareness about domestic violence. They donated in her name to My Friend’s House, a domestic violence shelter in Collingwood. Andrea Canning shared in the episode that her own family had donated to the shelter long before this case, which made her connection to the story feel even more personal.
In the end, the timeline, the testimony of their son, the lighter, the footprints, the insurance policies, the online searches, and every tiny inconsistency trapped James far more than anything he said in his interactions with the police. Investigators simply followed the trail that he left behind.
Why the case shook the community and how Dateline captured every step of the hunt for answers
Dateline treats the case almost like a puzzle that slowly falls into place. The show brings viewers into the snowy roads, the courtroom, the investigators’ offices, and the family’s memories. Every person interviewed adds another layer to the story.

The episode also reminds viewers that even people who appear to live normal, happy lives can hide things that no one expects. Ashley was a mom who worked hard, switched jobs to rebuild her life, and enjoyed hiking and golf. She lived in Collingwood with her children and her dog. Friends, siblings, and coworkers described her as warm and full of energy.
But behind closed doors, their marriage was strained. Infidelity, distance, and quiet tension kept building. Dateline shows how outward appearances never tell you the whole story of what maybe going on behind closed doors.
Investigators relied on the smallest clues. A child’s late night memory. A lighter with initials. A dog left behind when it was supposed to be on a walk. A cell phone text conversation that did not sound natural.
All those details were simple, everyday things that turned into big answers. And that is exactly why the investigation moved so fast. Detectives kept focusing on the basic truth. Accidents do not come with matching footprints and staged scenes.
Dateline captures this so well because it shows the real people who lived through it. Officers who worked through snowstorms to follow every lead. Family members who sat through court hearings. Journalists who watched the entire trial play out. And a whole town that still talks about that January morning.
The episode also explains that James is now serving his sentence in a correctional facility in Ontario. He will remain there until at least 2053 when he becomes eligible for parole.
The real tragedy is that two children have lost their mother and their father. And the community is still trying to make sense of how something like this could happen in a place where people normally just worry about the weather or the next ski weekend.
The Dateline special on the murder of Ashley Schwalm shows how investigators used patience, simple observations, and careful fact checking to uncover the truth. Nothing about the case was solved by one big clue. It was all small pieces that eventually pointed toward one person.
