Nearly 20 years after a young NSW mother went missing, police are offering a $1 million reward for information about her suspicious disappearance and suspected murder.
Amber Haigh and her six-month-old son had been living with a married couple in Kingsvale, a town in the South West Slopes, when she vanished on June 5, 2002.
The 19-year-old's disappearance is being investigated by a strike force which is treating it as a murder investigation, State Crime Command Homicide Squad Commander Detective Superintendent Danny Doherty said on Tuesday.
