The Lagos High Court sitting at Tafawa Balewa Square annexe on Friday found Dane Peter Nielsen guilty of two counts of murder of his Nigerian wife, Zainab, and daughter, Petra.
The judge, Bolanle Okikiolu-Ighile, delivered the judgment in a more than five-hour lengthy hearing, which started at about 11:15 p.m.
The Lagos State Government arraigned the 53-year old defendant on June 13, 2018, on a two-count charge of murder, punishable under Section 223 of the Criminal Laws of Lagos, 2015, which prescribes the death penalty if convicted.
He had pleaded not guilty to the charges.
Mr Nielsen was said to have killed his wife, a musician also known as Alizee, and his daughter on April 5, 2018, at about 3.45 a.m. at their Banana Island residence in the Ikoyi area of Lagos.
Mrs Okikiolu-Ighile based her decision on the post mortem examination led by John Obafunwa, a professor, on the deceased persons.
Mr Obafunwa submitted that the bruises found on the head and neck of Zainab were consistent with blunt trauma.
