Ottawa father killed two young sons before dying by suicide, police conclude

Google News CA — Crime (EN) reports that the Ottawa Police Service has released a detailed timeline of events surrounding the deaths of two boys and their father last month, formally concluding its investigation into the suspected double murder-suicide.

The two children, aged 7 and 12, were found dead at a home on Mandevilla Crescent on June 29. Their father, identified by police as 40-year-old Dr. Mohammad Al-Lami, was discovered dead inside a burning vehicle at a carpool lot along Highway 416 near Kemptville.

Investigators determined that the boys were killed by their father during the late evening of June 28 or the early morning hours of June 29.

"Al-Lami subsequently intentionally set fire to his dental practice in Iroquois before dying by suicide in a vehicle near Kemptville," police said.

Investigators examined all three scenes, conducted interviews, reviewed financial and digital records, and considered forensic and post-mortem findings. "The evidence established that Al-Lami acted alone. No other person is believed to have been involved, and there is no ongoing risk to public safety," police stated.

At the request of the boys' mother, police will not release the children's names publicly. No criminal charges can be laid, as the person responsible is deceased.

History of intimate partner violence

The investigation uncovered a pattern of domestic conflict preceding the killings. "The investigation also identified a history of intimate partner violence and continuing conflict involving parenting arrangements and financial support," police said. "While no single circumstance can fully explain this violence, the evidence indicates that these issues likely formed part of the context leading to the deaths."

Court documents show Al-Lami was serving a period of probation at the time of the incident, having been found guilty of threatening his ex-wife. In January 2024, he had been charged with threatening to cause bodily harm to her via email. In April of this year, he was found guilty and received a conditional discharge with 12 months of probation — meaning he would not have carried a criminal record had he complied with its terms. His conditions included no direct communication with his ex-wife, except through prior written consent, a third party, or a court order related to contact with his children.

Al-Lami had also faced a separate charge of threatening to cause bodily harm to a man in an email, also from January 2024. That charge was withdrawn in April 2026.

According to family court records from September 2024, Al-Lami had custody of at least one of his sons every other weekend under an existing court agreement.
