The deaths of two police officers in Kogi State following a reported breakdown of their romantic relationship have raised troubling questions about domestic violence, access to firearms and the Nigeria Police Force’s response to warning signs involving its personnel.
Corporal Amos Yusuf allegedly shot and killed his colleague and former romantic partner, Woman Corporal Grace Onimisi, before turning the gun on himself during a night-duty incident at ASCO Camp, an Ajaokuta Steel Company residential estate, on October 23, 2026.
While the Kogi State Police Command has confirmed the deaths and launched an investigation, accounts from people familiar with the officers’ relationship suggest that the tragedy may have been preceded by repeated disagreements, physical confrontations and threats.
More significantly, allegations that police authorities had previously intervened in the relationship have brought the command’s handling of the situation under scrutiny.
A relationship reportedly marked by violence
Investigations indicate that the officers had been romantically involved for several years before their relationship reportedly deteriorated over allegations of infidelity, mistrust and persistent disagreements.
A source familiar with the matter claimed that their disputes had repeatedly escalated into physical confrontations and threats.
The source alleged that the situation became serious enough for the Divisional Crime Officer (DCO) to intervene and detain both officers following one of their altercations.
According to the source, the DCO subsequently advised them to end the relationship to prevent further conflict.
“The two junior police officers had been dating for some years now, but a few months ago, they started having trust issues and cheating allegations. There had been physical fights and threats to the extent that they were detained at some point by the DCO, who later advised them to end the love relationship for the sake of peace,” the source said.
However, the reported intervention did not appear to resolve the situation, as disagreements allegedly continued.
The source further claimed that Yusuf could not accept Onimisi’s decision to end their relationship, suggesting that the breakup may have been the immediate trigger for the fatal confrontation.
These accounts have not been independently established, and the police investigation is expected to clarify the circumstances surrounding the incident.
What happened on the night of the killings?
On the day of the incident, Yusuf resumed his night-duty assignment as a station guard at about 6pm on October 23.
He allegedly left his assigned post around 9pm and went to Onimisi’s residential quarters with his service rifle.
An argument reportedly broke out inside her room, forcing the female officer to flee outside in an attempt to escape.
Yusuf allegedly pursued her and opened fire, hitting her several times before turning the weapon on himself.
Onimisi’s brother, Emmanuel Abraham, said his sister sustained gunshot injuries to different parts of her body.
“He shot my sister on the shoulder, lower abdomen and leg before Amos shot himself,” he said.
The police have yet to publicly establish the full sequence of events through their investigation.
What the police have confirmed
In a statement issued by the Police Public Relations Officer, ASP Saliu Oyiza Afusat, the Kogi State Police Command said the incident was reported at approximately 11:04pm.
The Divisional Police Officer, Ajaokuta, subsequently mobilised officers to the scene.
Preliminary police findings indicated that Yusuf allegedly shot Onimisi before turning the weapon on himself.
Both officers were rushed to separate medical facilities, where they were confirmed dead. Their remains were later deposited at the ASCO Hospital mortuary.
The police also confirmed the recovery of an AK-47 rifle and four expended cartridges from the scene.
The case was subsequently transferred to the State Criminal Investigation Department (SCID) for an in-depth investigation.
Commissioner of Police, CP Naziru Bello Kankarofi, expressed condolences to the families, colleagues and loved ones of the deceased officers.
The command also urged the public to avoid speculation, promising to release verified information as investigations progressed.
The unanswered question of institutional responsibility
Perhaps the most troubling aspect of the incident is the allegation that the officers’ troubled relationship was already known to their superiors.
If the reported detention, physical confrontations and threats are established, questions will arise about whether the administrative measures taken were sufficient to protect both officers.
Did the authorities adequately assess the risk after the reported altercations? Were appropriate measures taken to prevent further contact between the officers? Was Yusuf’s access to a service weapon reconsidered despite the alleged history of threats?
These are questions the ongoing investigation needs to address.
An engineer with the Ajaokuta Steel Company, Ozomata Nasiru, criticised what he described as a lack of proactive action by the police hierarchy.
He argued that transferring one of the officers after their disagreements became known could have reduced the possibility of further confrontation.
“The police Ogas are not proactive in their conduct. They should have transferred one of them when they noticed that the two were having problems,” he said.
Another resident, Idris Momoh, called for greater attention to the emotional and psychological welfare of police personnel.
He argued that the responsibilities of the police hierarchy should extend beyond operational duties to include identifying officers experiencing serious personal difficulties and providing appropriate support.
However, whether the reported warning signs were formally documented, the extent of the command’s knowledge and the adequacy of its response remain matters for investigators to establish.
A family demanding answers
For Onimisi’s family, the tragedy has left behind grief and questions about whether her death could have been prevented.
Her mother, Mrs Abraham, who is also a serving police officer in Plateau State, said she was still struggling to come to terms with the loss.
“I am still in shock up till now,” she said.
She reportedly collapsed after receiving news that her daughter had been killed by a colleague with whom she was romantically involved.
The family wants the circumstances surrounding the killing thoroughly investigated and those responsible held accountable where necessary.
Her brother also expressed the family’s determination to understand what happened, particularly given the alleged history of disagreements and threats.
What the investigation must establish
With the SCID handling the case, the investigation is expected to establish the circumstances of the shooting and examine the evidence recovered from the scene.
Beyond determining the sequence of events, the investigation faces a broader institutional question: whether earlier interventions by the police authorities were adequate, particularly if allegations of previous violence and threats are substantiated.
The recovered AK-47 rifle and four expended cartridges are among the exhibits identified by the police. The command has not publicly confirmed the outcome of any ballistic examination.
The findings could help clarify the shooting, while statements from colleagues, family members and other witnesses may provide further insight into the events preceding the deaths.
Relationship experts Ntomoh Alex and Greatnest Ekppang have also cautioned against ignoring dangerous warning signs in romantic relationships, urging people to prioritise their safety and leave relationships that become threatening or abusive.
Ultimately, the deaths of Yusuf and Onimisi raise issues that extend beyond a relationship breakdown.
They concern how domestic and workplace conflicts involving armed personnel are identified, how threats are handled and whether existing police welfare and disciplinary mechanisms are adequate to prevent foreseeable harm.
Until the SCID completes its investigation, the allegations surrounding the officers’ relationship and the command’s earlier intervention remain unproven.
But one question will remain central to the search for answers: If the reported threats and physical confrontations were already known to the authorities, could more decisive action have prevented two police officers from losing their lives?
