About one month after Cynthia was laid to rest, the trial commenced at Yaba Magistrate court, Lagos on August 27, 2012. Six people were arrested at the beginning of the investigation, they included: Olisaeloka Ezike, 23, and Okwuno Nwabufor, 33; both of whom were identified as the Facebook friends. Others were Osita Orji, the pharmacist who sold Rohypnol to them and Nonso Ezike, Olisaeloka's brother who assisted in selling the deceased's Blackberry phone. The six-count charge of conspiracy, murder, armed robbery, rape, “unlawful administration of obnoxious substance” and “forceful administration of obnoxious substance” with a view to causing bodily harm were read to them. The trial commenced with the prosecution, the Lagos State Government calling its first witness. Okwumo Nwabufo and Olisaeloka Ezike were charged with conspiracy to commit murder and felony. Orji Osita, a pharmacist, was charged with negligently selling the Rohypnol Flunitrazepan tablets to Ezike, the 2nd defendant, without a doctor's prescription and without showing due care. Nonso Ezike (Nwabufo's younger brother) was charged with being in possession of the three stolen blackberry mobile phones belonging to the late Cynthia Osokogu. All the accused initially pleaded not guilty to all six counts. Justice Olabisi Akinlade of the Lagos High Court sitting at Igbosere admitted as evidence, confessional statements of the culprits recorded in a video. When the first defendant was arrested, he confessed that he knew what he did and that everything was over. The first defendant then operated the Blackberry phone to reveal the chain used in tying his victim. The first defendant was arrested on August 20, 2012, after which he made the confessional statement. The Attorney General of Lagos State, Mr Ade Ipaye, prosecuted the murder suspects, revealing details of pictures from the crime scene in the court from a laptop. The witness added that he and his team followed the first defendant to his home in Festac and recovered the said laptop, along with some phones and various network SIM cards. On that same date, the first defendant was asked to open the laptop, which he carried by himself to the Area Commander's office. "Pictures of the deceased lying down and her international passport lying on her chest was revealed”, the witness said. Another prosecution’s witness testified that from his investigation, it was discovered that the fourth defendant (Nonso) received different stolen phones from the first and second defendants on three occasions. The fourth defendant stole somebody’s receipt in Ladipo Market which he used in selling the deceased’s phone to someone in Port Harcourt and the person was arrested. The witness also told the court of another investigation against the defendants, in two separate hotels- Chelsea Suit and Penny Hotel,Festac, where they were alleged to have carried out similar acts. The cases were separated because the incidents did not happen on the same day. It was based on the confessional statement by the first and second defendants that they carried out similar acts in other hotels in Festac. In one of his appearances in court, Nwabufo denied ever knowing about Rohypnol nor did he put it into Cynthia’s drink. He also claimed that Cynthia was his lover and that they were planning to get married before her death. Nwabufo said he met her at Shoprite Mall in Lekki in 2011 where he went for shopping, while she was also shopping at a fashion shop, dismissing the allegations that they met on Facebook. He also added that when he met her, she was making inquires so he introduced himself to her and she did the same, adding that they exchanged contacts afterwards. He also said that they developed friendship after exchanging addresses and became very close since then. However, there has been no sufficient evidence to warrant this claim. The judge also dismissed the claim by Mr. Nwabufor that Ms. Osokogu was his fiancée and was going to introduce him to her father, saying that the "lover's" story was false because under cross-examination Nwabufor could not tell Cynthia's birthday, the name of her mother, her home town or, in fact, anything about her. Though the convicts pleaded not guilty and tried to withdraw the confessional statements they made to the police claiming they were made under duress, the court admitted the statements they made were corroborated by the testimonies of the witnesses and the evidence provided by the police. The judge said the fact that the police produced a video footage of the convicts making the confessional statements also helped in countering the claim by the convicts that they made the statements under duress. The court was satisfied that the confessional statements were not given under duress and admitted them in evidence. A confession is sufficient to gain conviction, the judge said. The confessional statement of the accused is consistent with the state of the body and consistent to the medical evidence. The judge said she would act on it accordingly. While delivering the judgement, the judge said the accused deserved the sentence as they were not remorseful of their action, and were telling the court lies after offering confessional statements to the police. The judge also found the duo guilty on three other counts and sentenced them to a total of 20 years imprisonment each. They were sentenced to 14 years in jail for conspiracy to commit murder, three years for conspiracy to commit felony by stealing, and three years for stealing a Blackberry phone. The judge acquitted and discharged Osita and Nonso. While delivering the judgement, Mrs. Akinlade said she relied on the evidence and testimonies provided by the prosecution. She said, having carefully analysed the evidence and testimonies before the court, the prosecution proved beyond reasonable doubt that Messrs. Nwabufor and Ezike murdered Ms. Osokogu. The judge stated that the evidence of the prosecution remained uncontroverted and relies mainly on the testimonies of witnesses and evidence. It was also very clear that the first defendant was untruthful and deceived the court. In sentencing both men to death by hanging, the judge said it was no longer relevant to know who, between the two, actually killed Ms. Osokogu. The second defendant acted in consent with the first defendant and will bear the consequences of their action irrespective of whoever committed the offence. The Judge held that with its 10 witnesses and 17 exhibits, the prosecution's case against Nwabufo and Ezike was uncontroverted and that the circumstantial evidence brought by the state was “cogent, complete, unequivocal and compelling.” The judge held that the circumstantial evidence brought by the state in proof of the six counts of conspiracy, murder and stealing against the accused persons were cogent, complete, unequivocal and compelling. Counsel for Orji and Nonso had requested bail for their clients and Justice Akinlade had granted bail to Orji with two sureties. The court granted bail to Orji Osita and Ezike Nonso, while the other two who allegedly committed the offence of murder were remanded at the Kirikiri prison, Lagos. For Nonso, Olisaeloka's younger brother, the judge granted him bail with two sureties, adding that one of the sureties must be a civil servant not less than Grade Level 14 while the other must be a property owner with a genuine Certificate of Occupancy. On March 23, 2017, the Lagos state high court, Igbosere, sentenced Nwabufo and Ezike to death by hanging.
