Armadale (Edinburgh Daily) September 19, 2026 – Police Scotland has confirmed that two more men have been formally charged in connection with the fatal shooting of 35-year-old William “Billy” Watson inside a residential property in Armadale, West Lothian.

The suspects, aged 29 and 44, were taken into custody following extensive enquiries by Major Investigation Team detectives and are expected to appear at Livingston Sheriff Court on Monday, 21 September 2026. The updates follow the initial arrest and court appearance of 57-year-old Frank McCarthy, who was charged with murder and attempting to defeat the ends of justice on Friday.

What Happened on Harestanes Road in Armadale?

Emergency services were dispatched to a residential address on Harestanes Road, Armadale, at around 11.50am on Saturday, 12 September 2026, following reports of an injured man inside the building. Upon arrival, first responders located 35-year-old local father William “Billy” Watson. Medical personnel pronounced him dead at the scene.

Following an initial assessment of the scene and a subsequent post-mortem examination, Police Scotland reclassified the investigation from a sudden death to a murder probe. Officers verified that Watson’s fatal injuries were consistent with gunshot wounds.

As reported by Edinburgh Live, police officers established a wide cordon around the property on Harestanes Road while forensic teams and detective constables conducted detailed site searches and door-to-door enquiries.

Who Has Been Charged and What Are the Court Proceedings?

Three individuals have been formally charged by law enforcement in relation to the incident.

As reported by The Herald, 57-year-old Frank McCarthy, residing in Bathgate, was the first suspect to appear in private at Livingston Sheriff Court on Friday, 18 September 2026. McCarthy faced charges of murder and attempting to defeat the ends of justice. During the petition hearing, McCarthy made no plea, was submitted to further examination, and was remanded in custody by the presiding sheriff. He is scheduled to make a secondary court appearance within eight days.

As reported by STV News, two further men, aged 29 and 44, were arrested on Friday, 18 September 2026, before being formally charged by Police Scotland. Both individuals remain in police custody ahead of their scheduled appearance at Livingston Sheriff Court on Monday, 21 September 2026.

What Information Have Police Scotland and Investigating Officers Released?

Police Scotland officials have maintained that while firearms offences remain rare in the Lothian region, this event is being treated as a specific and isolated occurrence.

As reported by Ground News, Superintendent Jocelyn Thomas stated:

“We believe this was a targeted attack and while incidents of this nature are rare, I understand the concern this will cause to the local community. An increased police presence will remain in the area while our investigations continue.”

In addition, as reported by Ground News, Detective Superintendent Michelle Findlay urged members of the public to provide any relevant detail, stating:

“Our enquiries are ongoing to establish the full circumstances and why Mr Watson was targeted. I am appealing to anyone who was in the area at the time, or who has information that could assist our investigation, to contact us.”

Detectives confirmed that forensic analysts have been examining two specific motor vehicles identified during initial investigations: a blue BMW and a black Vauxhall Mokka. Authorities also noted that four men seen in the vicinity of Harestanes Road around the time of the incident remain part of line-of-enquiry tracing.

Police Scotland has asked anyone with potential dashcam, CCTV, or doorbell footage from Harestanes Road and surrounding streets between Friday night and Saturday noon to submit files via the Major Investigation Public Portal (MIPP) or contact Crimestoppers anonymously on 0800 555 111.

Background of the Development

The fatal shooting in Armadale occurs against a broader socio-geographic backdrop in West Lothian, a region located between Edinburgh and Glasgow. Historically industrial, Armadale is a small town where violent crime involving firearms is statistically uncommon compared to urban centers. Under Scots Law, serious crimes involving firearms automatically trigger the deployment of Police Scotland’s Specialist Crime Division and Major Investigation Teams (MIT).

Over recent years, Police Scotland has maintained dedicated operations addressing serious organized crime groups and illicit firearm distribution within the central belt of Scotland. Because firearm possession is strictly regulated under UK law via the Firearms Act 1968 and subsequent amendments, any homicide involving a gun prompts significant forensic, ballistic, and intelligence-led investigations.

The escalation from an initial emergency response to a full murder investigation involving multiple arrests reflects the investigative protocol deployed in potential targeted gangland or dispute-related shootings within Scottish jurisdictions.

Prediction: How This Development Can Affect the Local Community and Public Stakeholders

The ongoing judicial proceedings and police presence in Armadale are expected to have several short- to medium-term impacts on the local community, police operations, and local governance:

• Impact on Local Residents and Community Safety Perceptions: The public confirmation of a targeted firearm attack within a residential neighborhood can heightened anxieties among residents on Harestanes Road and the wider West Lothian area. While Police Scotland has deployed high-visibility patrols to reassure the public, community members may observe continued disruptions due to police cordons and forensic work.
• Impact on Local Policing Strategies: Police Scotland is likely to sustain an elevated uniform presence and targeted intelligence gathering across West Lothian in the coming months. This development may lead local division commanders to reallocate resources toward anti-violence monitoring and proactive vehicle checks in surrounding towns such as Bathgate and Livingston.
• Impact on the Legal System and Court Timelines: With three co-accused individuals entering the Scottish solemn court procedure at Livingston Sheriff Court, the case will progress through committal hearings toward a full High Court trial. Given the complexity of firearm homicides, multi-defendant forensic analysis, and digital evidence gathering, legal proceedings are projected to span several months, drawing significant regional court resources and media focus through late 2026 and 2027.
