Alexander McKellar, also known as Sandy McKellar, is a Scottish farmer and former gamekeeper whose name became widely known because of a criminal case involving the 2017 death of cyclist Tony Parsons. For years, the circumstances surrounding Parsons’ disappearance remained unresolved. The case eventually took a dramatic turn when McKellar confessed to his then-fiancée, Dr. Caroline Muirhead, in 2020.
McKellar was later convicted in Scotland of culpable homicide and attempting to defeat the ends of justice. His twin brother, Robert McKellar, was also convicted for his role in concealing what happened. Alexander received a 12-year prison sentence.
Although McKellar was not a public celebrity before the case, renewed attention came in 2026 when Netflix released Should I Marry a Murderer?, a documentary series examining the case through Caroline Muirhead’s experience.
Because McKellar lived a relatively private life before his arrest, many details about his childhood, education, finances, and personal background remain limited in public records.

Who Is Alexander Mckellar?
Alexander McKellar is a Scottish man who became known publicly after being linked to the disappearance and death of Tony Parsons, a 63-year-old cyclist who went missing in the Scottish Highlands in September 2017.
McKellar had been working as a farmer and gamekeeper in the Bridge of Orchy area. He was also known as an enthusiastic hunter and deer stalker. Before the criminal investigation, there was little public information about his personal life because he was not a public figure.
The case changed dramatically several years after Parsons disappeared. In 2020, McKellar told his fiancée, forensic pathologist Dr. Caroline Muirhead, that he had been responsible for hitting Parsons with his vehicle in 2017. Muirhead subsequently became involved in helping authorities uncover what had happened.
Investigators eventually located Parsons’ remains, and McKellar and his twin brother Robert were arrested. Both men initially faced murder allegations but later entered pleas to lesser charges before their trial.
In August 2023, Alexander McKellar was convicted of culpable homicide and attempting to defeat the ends of justice. He was sentenced to 12 years in prison.
Early Life and Background
Public information about Alexander McKellar’s childhood is limited. Reliable sources describe him as being born and raised in Scotland, but his exact date of birth, parents’ names, childhood home, and detailed family history have not been publicly established.
McKellar grew up in a rural Scottish environment and later worked in agriculture and gamekeeping. He and his twin brother Robert were associated with the Auch estate near Bridge of Orchy in the Scottish Highlands.
His work was closely connected to the countryside. Reports describe Alexander as a farmer and an avid hunter who took part in deer stalking. His professional life therefore appears to have been centered around outdoor and agricultural work rather than entertainment, business, or public-facing professions.
There is also no reliable public record providing extensive details about his formal education. Information about schools, qualifications, or university attendance has not been widely reported by reputable sources.
That lack of information is important when discussing McKellar. Much of what is publicly known about him comes from court reporting and coverage of the Parsons case rather than from interviews or biographical material published by McKellar himself.
Career Journey
Alexander McKellar’s working life was connected to farming and gamekeeping in the Scottish Highlands.
Before the events that brought him into the public eye, he was reportedly working alongside his twin brother Robert in the Bridge of Orchy area. He was also involved in deer stalking and hunting, activities that were part of his rural lifestyle.
According to reporting, McKellar had been drinking at a hotel after a successful hunting trip on the night of September 29, 2017. Later that evening, he was driving when his vehicle struck cyclist Tony Parsons on the A82 between Bridge of Orchy and Tyndrum.
Parsons had been completing a long charity cycling journey when he was hit. Rather than contacting emergency services, McKellar and his brother left the scene. The brothers subsequently concealed evidence connected with the incident and buried Parsons’ body on the estate.
Parsons’ disappearance became a major missing-person case. Extensive searches were conducted, but investigators were unable to locate him for more than three years.
The case eventually moved forward after McKellar began a relationship with Caroline Muirhead in 2020. During their relationship, he confessed to her that he had been responsible for the incident. Muirhead then began gathering information and cooperating with police.
Police eventually found Parsons’ remains, and the investigation resulted in the arrest of the McKellar brothers.
The legal proceedings concluded in 2023. Alexander pleaded guilty to culpable homicide and attempting to defeat the ends of justice and received a 12-year sentence. His twin brother Robert received a sentence of five years and three months for his involvement in concealing the crime.
The case received renewed international attention in 2026 through the Netflix documentary series Should I Marry a Murderer?. The production focuses particularly on Muirhead’s experience, including the moment she learned about McKellar’s role in Parsons’ death and the difficult decision she faced after his confession.
Personal Life
Alexander McKellar’s personal life has largely remained outside the public spotlight, although his relationship with Caroline Muirhead became a major part of the story surrounding the case.
Muirhead was working as a forensic pathologist in Glasgow when she met McKellar through the dating app Tinder in 2020. The two began a relationship and she spent time with him in the Scottish Highlands.
Their relationship became central to the investigation after McKellar revealed his involvement in Parsons’ death. According to reporting, Muirhead was initially shocked by what she heard but ultimately helped authorities gather information that contributed to solving the case.
The couple did not marry. Their relationship ended following McKellar’s arrest and subsequent conviction.
McKellar also has a twin brother, Robert McKellar. Their connection became significant in the criminal investigation because Robert was involved in the concealment of Parsons’ body and other evidence.
Beyond these publicly documented relationships, there is limited reliable information about Alexander’s wider family life. Details about his parents, other relatives, children, or hobbies outside hunting and rural work have not been extensively reported.
Height
Alexander McKellar’s height has not been reliably documented by reputable public sources. Although some websites may publish an exact figure, there is no strong evidence establishing a verified measurement.
For that reason, it would be misleading to present a specific height as fact. Readers looking for more detailed information about Alexander McKellar’s height should treat unofficial figures with caution.
Estimated Net Worth
There is no reliable public estimate of Alexander McKellar’s current net worth. His professional background has been associated with farming and gamekeeping, but publicly available reporting does not provide enough verified financial information to calculate his assets, income, or overall wealth.
Because he was not a public entertainment figure or business personality, financial information about him has never been widely documented. His involvement in the criminal case also means that most reputable coverage has focused on the investigation, court proceedings, and Tony Parsons rather than personal finances.
Any exact net-worth figure circulating online should therefore be treated as unverified unless supported by credible financial records.
