Earlier in the night she’d had dinner with her parents, Ann and Spike Jones, and was due to arrive at St John of God Hospital for work at 9.30pm.
At 9.40pm, a colleague called Ms Nicholson’s brother, Andrew, asking if he knew where his sister was.
Concerned, Andrew and Mr Jones drove to Ms Nicholson’s house to find her car parked in the driveway.
They then discovered her battered body lying face down on the porch, dressed in her nurse’s uniform.
Ms Nicholson’s parents now claim she told them she had heard noises outside her home and felt like she was being watched in the months before her murder.
Detectives believe Ms Nicholson was involved in a violent struggle before her death, and suffered serious head injuries.
A $1 million reward f,o,r information leading to the arrest of her murderer has been offered by Victoria Polic,e.
“A reward of up to $1 million dollars will be paid at the discretion of the Chief Commissioner of Police, for information leading to the apprehension and subsequent conviction of the person or persons responsible for the death of Nina Nicholson,” Acting Sergeant Melissa Seach told the Herald Sun.
Investigations by the homicide squad into the cold case are ongoing. Anyone with information is urged to contact Crime Stoppers on 1800 333 000.
