The convict was arrested by the men of the Ondo State Police Command after killing the deceased, who was a student of the Rufus Giwa Polytechnic, Owo, in February 2017 at Ogbese in the Akure North Local Government Area of the state.
Before the killing, Onweniwe was said to have abducted the deceased and taken her to a farm near the community, where he r*ped her, after which he strangled her to death.
When the trial began in May 2017, the convict was arraigned before the court on four counts of action endangering life, kidnapping, r*pe and murder.
After examining all the facts of the case, the court held that on three of the counts, the prosecution proved its case beyond reasonable doubt except for the third count of r*pe, which the prosecution did not provide the evidence against the convict
While delivering his judgement, the trial judge, Justice Samuel Bola, said the autopsy that was conducted on the deceased showed the abnormal state of her neck and the fracture of her skull.
He added that the autopsy also indicated that the deceased had been attacked with an object with a blunt edge, which led to her death.
The judge found Onweniwe guilty as charged on three counts and sentenced him appropriately.
On the count of kidnapping, the court sentenced Onweniwe to life imprisonment, while on the count of strangulating to death, the convict was sentenced to death by hanging; and on murder, he was also sentenced to death by hanging.
