A forensic scientist says examining the bones of two children found hidden in suitcases could reveal vital details of how they were treated during their young lives and what happened to them and when. An Auckland family made the grisly discovery after buying the contents of an abandoned storage locker in an online auction - but are not involved in the incident. Police yesterday revealed the children could be aged between five and ten and may have been in the suitcases for some time. Otago University lecturer Doctor Angela Clark is a forensic anthropologist who also works with police and in the justice system.
