The lawyer representing the family of Nora Quoirin says it's too early to rule out a possible criminal element in her death.
According to the Irish Daily Mail, Charles Morel said it was highly improbable that she voluntarily disappeared almost a fortnight ago.
The body of the 15 year old - who had learning difficulties - was found in Malaysia on Tuesday.
A post mortem revealed she died of internal bleeding due to hunger and stress.
