His victims were identified as Mrs. Alice Omorogbe 52, Mrs. Blessing Efe 25 and her baby.
A two-year-old girl inside the room at the time of the attack was spared.
The mutilated bodies of victims were discovered the following morning.
Edoghogho said he killed his in-laws because of the way they were hiring boys to beat him anytime he had issues with his wife.
On his confessional statement, he said “I am a tipper driver but since the rains started I was doing menial jobs.
“I killed them out of annoyance because my mother -in- law used boys to beat me up. She would say I am talking to my wife. If I quarrel with my wife, she will send boys to beat me up.
“I didn’t know the cutlass will meet the baby. After I killed them, I ran away. Later I came out and went to tell my father what I did. I have not seen my wife since I killed her mother and sister.”
