Police are trying to find the mother of a baby whose body was found in a garden in Halifax six years ago.
An inquest into the death of the boy has been officially opened. His body was discovered wrapped in a bin liner during a refurbishment of a luxury home in Barkisland.
DNA tests have confirmed the baby's mother was Angela Owen, who is believed to have gone by as many as 27 aliases.
She has not been seen since June 2004 when she visited Weston Super Mare using the names Carla Geissler and Helen Gee.
