Police have seized several items including a knife from the home of Michelle Morrissey, who was found dead in central western New South Wales on Saturday.
Homicide Squad detectives are helping local police in Mudgee piece together the hours before her body was found in the Cox Street home at about 6:30pm AEDT.
Detectives have not revealed how the 19-year-old died but say her death is suspicious.
Yesterday a statement from the teenager’s mother was read out by police officers.
Sue Morrissey pleaded with the public to report anything to police that may help the investigation.
She asked people to think back to Saturday between 3:00pm and 6:00pm and bring forward any information, no matter how small.
She says they should report anything that happened in the area that they consider even slightly suspicious or unusual.
A post-mortem examination is expected to be carried out on the teenager this week.
