It was learnt that the 28-year-old Victoria, killed Gagariga, 33, at their residence on Ebisam Road in Akenfa area of the state.
Victoria was said to have stabbed him on the neck with a kitchen knife following a bitter quarrel over “a minor domestic issue” in the early hours of Thursday.
Sources said they had co-habited for some years before legalising their union in Yenagoa in June 2014, although the union had yet to produce any children.
Gagariga was said to have given up the ghost at a hospital where he was rushed to after losing a lot of blood.
His corpse, it was further learnt, had been deposited at an undisclosed morgue in the state.
Victoria, said to be a daughter of a retired director in the state Ministry of Information from Brass Local Government Area, is said to be an employee of the Bayelsa State Council for Arts and Culture.
Her husband Henry Gagariga was an indigene of Sagbama Local Government Area, also in the state.
When contacted, Police Public Relations Officer, Bayelsa State Command, Mr. Asinim Butswat, confirmed the incident.
“We will commence investigation to unravel the cause of death,” he said.
