THREE witnesses have testified in the trial of a truck driver who is accused of allegedly strangling a sex worker to death in his parents’ home in Nuwaidrat and incinerating her body on a farm in Sitra in a thwarted bid to hide the crime.Charged with premeditated murder, desecrating a corpse and using drugs, the 44-year-old Bahraini father-of-six earlier admitted to killing the Kazakhstani woman but claimed that it was ‘unintentional’ because he was ‘high and out of his mind’ .
