Case Summary
On November 17, 2004, a firebombing at a Calgary townhouse killed four-year-old Sajja Al-Mayahi and five-year-old Ali Al-Mayahi and seriously injured their mother, Salma B. The fire initially appeared accidental, but investigators later connected it to a conflict involving Salma, her husband Toin Al-Mayahi, and Manar Hussein, who was alleged to have had an affair with Toin. Michael Sheets and Ferum Kazar admitted setting the fire after being hired to scare Salma, while Abdulaziz Al Ahib was convicted of orchestrating the attack.

Relationship Pattern
Romantic Triangle
Pattern Analysis
The reported relationship conflict centered on Salma's belief that her husband was having an affair with Manar Hussein. That dispute reportedly produced harassment, threats, police complaints, and a peace bond before the fire. The criminal case later established that outside offenders were hired to intimidate Salma, but the court did not find that Hussein knowingly participated in the firebombing.
Investigative Notes
The fire was initially treated as potentially accidental, but scene examination, witness accounts, forensic testing, police records, cell-phone and cell-tower data, surveillance, and undercover operations redirected the investigation toward arson and homicide. Two witnesses reported that Michael Sheets and Ferum Kazar discussed making a Molotov cocktail, left after 1 a.m., and returned saying the deed was done. Sheets and Kazar pleaded guilty to two counts of manslaughter and arson causing bodily harm and received 15- and 16-year sentences. Abdulaziz Al Ahib was convicted of all charges and sentenced to 20 years. Manar Hussein was acquitted because the court found insufficient evidence that she knew about the plan in advance. The source reports that Sheets completed his sentence in March 2020, Kazar's sentence expired in April 2020, and Al Ahib's sentence ended in November 2023.
Investigation Confusion
The case initially appeared to be an accidental residential fire and investigators briefly considered mistaken identity because the family appeared unrelated to the drug house and alleged offenders. The two witnesses' accounts differed in some details, and investigators considered whether they might be redirecting suspicion. Later cell-phone records connected separate groups. Sheets made admissions during an undercover operation but was described as exaggerating some details, while Kazar's admissions were not initially considered a full confession. The alleged affair was disputed and was not judicially determined.
Case Reconstruction / Puzzle Pieces
On November 17, 2004, Toin left the family townhouse for security work while Salma remained with Ali and Sajja. During the night, attackers broke a window and threw a Molotov cocktail into the home, causing a rapid fire. Salma escaped through a second-floor window, but the children died inside. Investigators later learned of a prior visit by men asking for another person, an earlier conflict between Salma and Manar, and reports that Sheets and Kazar were hired to scare Salma. Cell-phone evidence, witness statements, undercover admissions, and later guilty pleas connected Sheets and Kazar to the fire and Al Ahib to its orchestration. Hussein's post-fire payment and alleged motive led to prosecution, but the court acquitted her for lack of proof of advance knowledge.
Risk Assessment
High relationship-linked risk was reported because suspicion of infidelity escalated into repeated harassment, threats, police involvement, and an alleged intimidation campaign. The eventual violence was carried out by hired offenders using a firebomb, causing two child deaths and serious injury to Salma. The source does not establish that the alleged affair itself occurred or that Hussein knew of the plan before the attack.
Key Takeaways
The source illustrates how suspected infidelity can become a prolonged conflict involving harassment, threats, public reputation concerns, and third-party intervention. A prior intimidation attempt and escalating police complaints were important warning signals. The incident also demonstrates the danger of outsourcing relationship retaliation to people motivated by money or drugs, particularly when the intended target's children remain in the home.
AI Case Q&A
What early signals mattered most?
The most important reported early signals were Salma's belief that Toin was having an affair, repeated hang-up calls, threats between Salma and Manar, police complaints, a death threat that led to a peace bond, and a prior visit by men persistently asking for another name at the townhouse.
Which clues helped connect the case?
The case was connected through two witnesses from a nearby drug house, their accounts of a planned firebombing, reports that Sheets and Kazar left and returned after the fire began, Sheets pointing out the burned residence, prior police information, cell-phone and cell-tower records, undercover admissions, and later guilty pleas.
Which evidence types appeared strongest?
The strongest reported evidence included witness statements, scene and forensic fire analysis, autopsy findings, cell-phone and cell-tower data, judicially authorized intercepted communications, undercover-operation statements, and the guilty pleas of Sheets and Kazar. The evidence against Hussein was insufficient to prove advance knowledge, according to the court.
Witness / Eyewitness Statements
Firefighters reported seeing the townhouse fully engulfed, Salma screaming for her children, and the children being found in separate bedrooms after an extremely difficult search. Two witnesses reported hearing plans to make a firebomb and later hearing that the deed had been done. Salma described hearing her son trying to breathe before the fire and later described persistent memories of her children. Police and court witnesses described the alleged conflict and payment, while Al Ahib gave a different account of the intended purpose.
How did follow-up reports change the understanding?
Follow-up reporting changed the case from an apparent accidental fire to an arson and double-homicide investigation. Later reports identified a relationship conflict, connected the alleged offenders through communications data, produced undercover admissions, and resulted in guilty pleas and convictions. The court ultimately acquitted Manar Hussein and declined to decide whether the alleged affair occurred.
What remained unclear?
The source leaves unresolved whether Toin and Manar actually had an affair, whether Hussein knew about the fire plan before it occurred, and the precise extent of each participant's knowledge at the time of the attack. It also reports that some early witness accounts differed and that investigators initially questioned whether the witnesses were redirecting suspicion.
