He gave the hint while testifying during a coroner’s inquest into the death of the singer on Wednesday.
The witness was cross-examined by defence counsel in the inquest.
It will be recalled that the musician died on September 12, 2023, at the age of 27 years.
His death generated controversies across the country and beyond, prompting Lagos State Government to direct a coroner’s inquest into the death.
The inquest, which began on October 13, 2023, is taking place at the Ikorodu Magistrates’ Court.
Somiari told the Coroner, Magistrate Adedayo Shotobi: “We expected to get the first set of autopsy results in three to four weeks and re-confirm to authenticate the cause of the death.
The forensic expert assured the public of adequate security and monitoring of samples for the autopsy.
“We have a place where items are stored for safety and security of results. There is a procedure for monitoring samples moved abroad,” he said.
