Akpan Uduak confessed to killing Umoren by using a stabilizer and pressing iron to hit her during an attempt to rape the deceased.
Uduak disclosed this while being paraded at the Akwa Ibom State Police Command on Friday.
The police were forced to parade the suspect following reports that there were efforts to bury the case.
Some news blogs had incorrectly reported that Uduak had committed suicide in police custody.
But speaking to the press during his parade, Uduak revealed how he lures his victim with reverse psychology and how Umoren unfortunately fell for it.
He had allegedly deceived the deceased that she was going to work as a secretary at a farm.
“I used reversed psychology on her. I asked her if she can work in the farm where hard drugs are kept as a secretary. And she said that she can and she is ready to take it.
“When she came, I told her this farm does not exist and there is a no farm like that, it was just a hoax and I told her that before she leaves, I will like to have sex with her and she agreed and she gave a condition that I should use a condom because of HIV.
“While I removed the condom, she became furious and she took the nearby stabilizer to hit me on my fore head then she hit me on my left ring finger and try to reach for the door, screaming.
“So, while I was bleeding, in a bid to stop her I used the stabilizer to hit her and when I hit her, she fell and started bleeding, and thereafter died,” he disclosed.
The suspect revealed to the press that Umoren was not his first victim, as six other women had fallen victim of his tactics of luring them through fake job alerts but, however, claimed that her death was his first murder.
However, the state commissioner of police, Andrew Amiengheme, said it was necessary to have the press conference because of the rumour that was going around in the media that the suspect had committed suicide in the cell.
“I don’t know anywhere in the world that a suspect will be allowed to use trousers in the cell to the extent of killing himself with it.
“Social media that is supposed to be a tool that will work to the advantage of the police has become something that is working against them,” he said.
