Hidden for 15 years in the back garden of an otherwise ordinary terraced house in Derby, the shallow grave of a young mother who once lived here is only now beginning to give up its secrets.

Izabela Zablocka was 30 and a tenant of the property with her female partner when she vanished without trace, having last spoken to her family in Poland in August, 2010.

She had moved to the two-bedroom home in the busy Normanton suburb, a mile from the city centre, the previous summer, leaving her then nine-year-old daughter with the child's grandmother as she fell into a new relationship.

When she disappeared suddenly and out of character, her family contacted police in Derbyshire who began a missing person enquiry.

But despite talking to her friends in the local Polish community and colleagues at Cranberry Foods Turkey and Chicken Factory in the nearby village of Scropton the trail went cold.
