A participant at a conference underway in Papua New Guinea on how to stop violence related to accusations of sorcery says the body of a woman brutally murdered before a crowd in February is still in the morgue.
Kepari Leniata's violent death at the hands of a mob in the Western Highlands provincial capital Mt Hagen followed accusations that she was responsible for the death of a six-year-old boy.
One of the participants at this week's conference and a worker with the Tertiary Students Christian Fellowship in Mt Hagen is related to Mrs Leniata's husband.
Ruth, who wishes only to be known by her first name, says as police officers were among those who watched the 20-year-old die they must be able to identify her killers.
"Someone saw what happened but no one's saying anything. Someone's afraid and is not coming forward. And that's what the police are saying, that, 'We don't have witnesses to this,' or, 'Unless we have witnesses, we can't go on with the investigation'."
Ruth says police also appear to be confused about new laws around sorcery.
