The mystery of how pregnant Scot Charmain Speirs died in a hotel room in Ghana will follow her husband until he dies, her mum said yesterday.

Grieving Linda Speirs spoke after an inquest in the UK failed to solve the riddle.

Coroner Caroline Beasley-Murray said: "We shall never quite know what happened. There just isn't the evidence."

But afterwards, Linda said of Charmain's husband, Ghanaian preacher and self-styled prophet Eric Adusah: "It's still hanging over him. It will hang over him for the rest of his life."

Charmain, 41, of Arbroath, died in March last year and the cause of her death is yet to be discovered.

She was found in the bath of the hotel room she had been sharing with Adusah in Koforidua in the Eastern Region. Reports at the time said she was face-down and had a towel wrapped round her.

Tests revealed Charmain died of heroin poisoning but her family refuted the claim saying she has never touched drugs.

Charmain was three months pregnant and had an eight-year-old son from an earlier relationship. She wed Adusah in 2014 after what her family called a whirlwind romance.

Adusah, who had flown to Ghana to preach, left for the UK two days before the body was discovered after reportedly telling hotel staff not to disturb his wife. She was only found after she failed to check out on time.

Adusah returned to Ghana and was held on suspicion of murder but the case collapsed for lack of evidence.

The inquest in Chelmsford, Essex, where Charmain and Adusah lived, rejected unlawful killing, suicide and accidental death and returned an open verdict.

A post mortem in Ghana found heroin killed Charmain.

A second examination in Britain eight months later was however hampered by the passage of time. It found evidence of drug poisoning but no signs of long-term heroin use, assault or death by natural causes.

Adusah, who preaches in London and Edinburgh, wore his wedding ring in court. He said his "name had gone everywhere" over the case but he had no idea what had happened.
