Woman's bid to uncover why mum vanished in 2010

The daughter of a woman who went missing 15 years ago has urged people to come forward with information, as a murder investigation continues.
Police said on Monday a body had been discovered as part of an investigation into the disappearance of Izabela Helena Zabłocka in August 2010.
Human remains were found in the garden of a property in Princes Street in Normanton, Derby, and are believed to be those of Izabela, according to Derbyshire Police.
Speaking just a few hours before the discovery, her daughter Katarzyna Zabłocka, now 24, told the BBC: "I would simply like to find out the truth."

Izabela was 30 when she disappeared, just a year after moving from Poland to Derby.
Derbyshire Police launched an investigation into the disappearance of Izabela after the force received a missing persons report in May.
Having spoken to her just days before her disappearance, Katarzyna, who was about nine at the time, said despite her family's attempts to trace her, she was never found.
Speaking to the BBC prior to the discovery of the remains, she added: "For those 15 years, we constantly wondered what happened; why she's not ing us, whether anything serious has happened so that she couldn't reach out to us.
"It was difficult for me and for those close to me. We suspected something bad could have happened."

As part of the investigation, Derbyshire Police said on Monday officers had arrested four people on suspicion of murder.
A 39-year-old woman was arrested and bailed over the course of the weekend. She has since been re-arrested, police said.
Three others - another woman aged 39, a woman aged 43 and a 41-year-old man - remain on bail.
Crime charity Crimestoppers is also offering a £20,000 reward for any information which leads to the conviction of someone in the case.
Katarzyna is now urging people with information to come forward and assist the police investigation.
"If anyone knows anything about this subject regarding my mum's disappearance and are still unsure whether to go to the police and say something, I would like to encourage them to do so because for a very long time I've been trying to uncover the truth and I really care about it - so does my family," she said
"If anybody knows anything, go, even anonymously, and the information to the police."
She added: "I would feel at peace that I succeeded, that I did everything I could to find out what happened and why."
