For years, Dennis Masomba Nyambane used his social media platforms to educate people on how to survive knife-stabbing incidents.

On some days, he would share those videos moments after completing life-saving operations in Kiambu Level 5 hospital theatres, meaning he had helped save lives in both physical and online spaces.

But in the spur of the moment, police believe that Dr Nyambane changed tune, from saving lives to taking one.

On Tuesday, Dr Nyambane stood before a magistrate at Kiambu Law Courts, where he is facing possible murder charges, as investigators and prosecutors argue that he stabbed his wife, Mary Mwende, to death last Friday.

That Dr Nyambane had a troubled marriage is not in dispute. That trouble may now be a contributing factor in the fatal stabbing of his wife.

The couple had moved into Busacarde Plaza in Kiambu barely two weeks ago. A simple two-bedroom apartment going for less than Sh20,000 per month.

Neighbours and a caretaker told reporters after the incident that for the last fourteen days, the couple had constant quarrels.

At around 8.30am on Monday, a woman’s voice, screaming in excruciating pain, woke up the neighbours.

Issac Omare, the caretaker, said one of the neighbours informed him of the stabbing incident. The tenant requested him to call for an ambulance, but it was too late because Ms Mwende, a mother of a three-year-old, had already succumbed to the injuries.

She was killed right in front of her child.

“'I was informed by one of the neighbours about the stabbing incident. She requested that I call for an ambulance but it was too late because as we struggled to get one(ambulance) the victim had already died,” Mr Omare told reporters.

Bloodied staircase

Neighbours on Wednesday said that the deceased had tried to escape after being stabbed several times on the chest.

This is corroborated by Mr Omare, who said that after the incident, there was a lot of blood on the staircase and it seems the deceased was trying to escape from her killer but succumbed before getting to the ground floor.

Police have turned their focus to finding the murder weapon, which is still missing.

Detectives investigating the matter told Nation on Wednesday that they are tracing it as an exhibit.

“All indications show the killing is related to a marital dispute and there is no need to kill each other when such happens,’’ Ms Constance Wangui, who lives at Busacarde Plaza, said.

On Tuesday, the court allowed an application by the prosecution team to detain Dr Nyambane for seven days to allow investigations and subject the accused to a mental assessment before he takes a plea.

Dr Nyambane is a 36-year-old consultant surgeon at Kiambu Level 5 Hospital. He and Ms Mwende had moved to Buscarde Plaza from another block of apartments nearby.

They had yet to establish close friendships with any of their neighbours.
