An in-law of the murder suspect told reporters that Ogah has been known for his mental illness but has never displayed acts of aggression.
Ogah's wife, Omago was also reported to be suffering from a medical disability termed as imbecility, report says.
Robert Onwusoaka, an in-law to the man said the serial murders occurred at the early hours of Saturday, October 8, 2016.
“I was curious when in the morning when I did not see Ogah’s wife who used to wake up early to sweep the compound, so I sent my son to go and check what she was still doing inside the room."
“My son came back telling me he did not see anybody but saw stains of blood everywhere in the room.”
“So, I quickly rushed to the house of the chairman of the community to alert him of the development and while returning with the chairman, I saw people who gathered and were wailing."
“Ogah dragged the bodies of his wife and daughter to a school toilet near the house."
“The police came to the scene on invitation by residents and they evacuated the bodies to the National Hospital mortuary."
According to Onwusoaka, there was no altercation between the murder suspect and the victims.
He admitted that Ogah has a mental problem, but that has not prevented him from performing domestic assignments.
“There was no problem between the man and his wife. I was the one taking care of them. Ogah did not use to stay at home, he used to go to the farm and return at night."
“He has mental problem, but it does not disturb him as he can farm very well. A day before he committed the murder, he ironed my clothes and polished my shoes."
“He can do anything as a human being just that his senses are not okay. He does not fight people. It is only his farm he would complain about."
"He would come back and complain that people went into his farm. Any time he goes to the farm and discovers that people went there and destroyed anything, he would come back to complain and make trouble with himself."
“He does not like anybody to touch his things. We, including his wife, don’t touch his things. I have been responsible for taking care of the wife and child.”
Speaking concerning the murdered wife, Onwusoaka said “You could describe her as a half imbecile.”
According to the Daily Post News, the Mpape Police Divisional Headquarters are currently investigating the incident and have kept the murder suspect in their custody.
