Diezani not dead lawyer
You're referring to Diezani Alison-Madueke, the former Nigerian Minister of Petroleum Resources who has been accused of corruption and is currently facing trial in Nigeria.
According to reports, Diezani Alison-Madueke is not dead. She was arrested in 2015 by the Economic and Financial Crimes Commission (EFCC) and has been in custody since then. She has been charged with various corruption-related offenses, including money laundering and bribery.
In 2020, Diezani Alison-Madueke was arraigned in court and pleaded not guilty to the charges against her. Her trial is ongoing, and she is currently being held in a detention facility in Abuja, Nigeria.
It's worth noting that there were earlier reports of Diezani Alison-Madueke's death, but these were later denied by her lawyers and the EFCC.
