The SIU is required to investigate all reports of deaths, serious injuries, or sexual assaults in relation to provincial or municipal police officers. Two Ottawa Police Service officers who were involved in the arrest – Constable David Weir and Constable Daniel Montsion – were designated as subject officers during the course of the investigation. Constable Weir was later re-classified as a witness officer, while Constable Montsion would be charged with manslaughter. On March 6, 2017, the SIU laid charges against Constable Daniel Montsion for manslaughter, aggravated assault, and assault with a weapon in relation to the death of Abdi. All evidence has been presented in the case but the decision is not expected until mid- or late 2020 at the earliest. The Abdi family retained lawyer Lawrence Greenspon two days after his death on Wednesday July 27. Abdi's funeral was held on Friday, July 29 at the Ottawa (Main) Mosque, with 800 inside and more outside. Naeem Malik, President of the Ottawa Muslim Association, estimated total attendance at over 2,000 people. The funeral was led by Imam Mohamed Hachimi and a family statement was read by Imam Sikander Hashmi of the Kanata Muslim Association. Mayor Jim Watson spoke at the funeral. The Canadian Somali Mothers' Association called for two officers to be removed and the Canadian Council of Muslim Women requested a critical look at the case. In late August, Black Lives Matter's Toronto chapter protested the SIU in Mississauga in response to Abdi's death.
