The pastor accused of killing his Tayside-born wife in Ghana told police she had threatened to commit suicide in the weeks before her death.
Three-months pregnant Charmain Adusah, formally Speirs, was found dead in a bath in a hotel in Koforidua on March 20.
Her husband Eric, the leader of the London-based Global Light Revival Ministries, was charged with her death but was released on bail after a report by the county’s attorney general said there was insufficient evidence to hold him liable.
More details of this report have now emerged, with Mr Adusah claiming his wife had threatened to kill herself and their unborn child.
The claims have been completely dismissed by Charmain’s family.
The report, signed by principal state attorney Evelyn Keelson, says: “The suspect claims in his statement that the deceased had been threatening to abort her pregnancy or kill herself.
“According to him, some of these threats were contained in messages sent to him by the deceased on his phone.
“There is, however, nothing on record to show that these messages have been traced or identified on either the suspect’s or the deceased’s phone.”
It also states Mr Adusah made similar comments to Bishop Yaw Adu.
It adds that an interim autopsy report states Charmain died from a heroin overdose, though no evidence of drug taking was found at the hotel.
The document continues: “The medical officer’s interim report on the deceased shows that she did not die from a natural cause.
The interim report states the cause of death briefly as acute poisoning, opiate (heroin).
“There is, however, no direct evidence on record as to how her body got poisoned by heroin.
“There is also no evidence on record indicating that she used heroin or narcotic drugs.”
Charmain’s mother Linda Speirs, who lives in Arbroath, dismissed Mr Adusah’s claims that her daughter was considering suicide.
She said: “It’s a lot of rubbish. He claimed that she threatened to commit suicide on text messages yet these weren’t found on his phone.
“When she arrived in Ghana (at the end of February) he texted me to say that Charmain was happy and had been swimming and shopping and that she was being treated like a queen.
“That doesn’t sound like someone thinking about suicide and she would never touch drugs.”
Linda’s sister, Beverley Crighton, has started an online petition calling on the British Government to get involved in the case.
The family want a coroner to carry out an autopsy on behalf of the family and for the Government to become involved in bringing her body home.
Since the Justice for Charmain petition started on the GoPetition website on Sunday, more than 450 people have signed the appeal.
