This was confirmed by the Lagos Coroner Court sitting in Ikorodu on Wednesday.
The state counsel, O. Akinde, revealed this known during the ongoing inquest on Wednesday.
Akinde told the Coroner Magistrate, Adetayo Shotobi, that the autopsy into the external body of the deceased had been completed, hence the need for the test.
He said: “The toxicology test, which has to do with the internal body, is being done in the US.”
His disclosure followed the insistence of the counsel to the father of the deceased, David Fadimu, on reasons for the delay of the test result.
Meanwhile, the Coroner, Magistrate Shotobi, had requested to know the reason behind the choice of a foreign toxicologist despite the presence of toxicology laboratories in Nigeria.
