Community Alert: Wanted Halifax Attempted Murder Suspect Arrested

Section 1: The Alert

Nova Scotia RCMP have confirmed the arrest of Matthew Francis Coaker, 37, of Halifax, who was the subject of a province-wide warrant for attempted murder. The arrest is linked to a serious stabbing that occurred in the early hours of March 28, 2026, on the 1800 block of St. Margarets Bay Rd. in Timberlea, where a 51-year-old man suffered life-threatening injuries.

On June 11, 2026, officers with the RCMP/Halifax Regional Police (HRP) Integrated General Investigation Section, supported by HRP’s Emergency Response Team, Quick Response Unit, and Critical Incident Program, arrested Coaker at a residence in the 0–100 block of Highfield Park Dr. in Dartmouth. A firearm was located and seized at the home, and a second person, Cheyenne Tanisha Amero, 34, of Kingston, was also taken into custody in connection with the case.

Section 2: Official Details

According to investigators, the incident dates back to March 28, 2026, around 1:35 a.m., when RCMP Halifax Regional Detachment and Emergency Health Services (EHS) responded to a report of an injured person on St. Margarets Bay Rd. in Timberlea. Responding officers found a 51-year-old man who had been stabbed following an altercation. The victim was transported to hospital by EHS with life-threatening injuries.

In April 2026, a province-wide warrant was issued for Matthew Francis Coaker in relation to this stabbing. At that time, he had already been charged with:

• Attempted Murder
• Possession of a Weapon for a Dangerous Purpose (related to the Timberlea stabbing)

During the coordinated arrest operation on June 11, 2026, officers located and seized a firearm at the Dartmouth residence. Following further investigation, both Coaker and Amero are now jointly facing a significant set of firearms and weapons-related charges:

• Possession of a Weapon Dangerous to the Public
• Unauthorized Possession of a Firearm
• Unauthorized Possession of Prohibited/Restricted Weapon
• Possession of a Firearm Knowing its Possession is Unauthorized
• Possession of Prohibited Weapon, Device or Ammunition Knowing its Possession is Unauthorized
• Possession of Prohibited or Restricted Firearm with Ammunition
• Possession of Weapon Obtained by Commission of Offence
• Possession of a Firearm Contrary to Order
• Unsafe Storage of Firearm

In addition to the above, each accused faces further charges directly tied to the original Timberlea incident:

• Matthew Francis Coaker: Aggravated Assault
• Cheyenne Tanisha Amero: Accessory After the Fact (for allegedly assisting Coaker in evading police)

Both Coaker and Amero are scheduled to appear in Halifax Provincial Court on June 12, 2026. The RCMP has publicly thanked community members for the information and cooperation that supported their efforts to locate and arrest Coaker.

Section 3: CrimeCanada.ca Safety Perspective

From the perspective of CrimeCanada.ca, this case highlights how quickly a violent altercation can escalate into a life-threatening situation and lead to complex weapons and firearms investigations. While the immediate threat from this specific suspect has been reduced by his arrest, residents across Nova Scotia should remain attentive to signs of escalating conflict, particularly late at night and in residential or mixed-use areas.

We encourage community members to contact police promptly if they witness weapons being displayed, hear threats of violence, or observe suspicious activity around homes or vehicles. Swift reporting can give officers the time they need to intervene before a situation turns deadly. When safe to do so, note details such as vehicle descriptions, licence plates, clothing, and direction of travel. Data gathered from such incidents also feeds into broader safety analysis, similar to how we compile information for communities like Coaticook crime statistics and safety data, helping authorities and the public understand where and how violence is occurring and how to prevent it.

CrimeCanada.ca remains committed to providing clear, accessible summaries of official police information so that the Nova Scotia community can stay informed, support investigations when requested, and make daily safety decisions based on reliable data.
