Nineteen year old Elizabeth was last seen handing in a university assignment in April 1999.
The 'considerate' and 'responsible' Vietnamese student was recorded on CCTV walking past west London's Ealing police station on her way back from Thames Valley University at 6pm.
She was just a mile away from her home.
When she didn't arrive back, her family instantly knew something was wrong.
In an interview in 2012, her brother Minh Chau said: "She was a very responsible girl and would always contact us if she was going to be late."
A lack of witnesses stymied the investigation into Elizabeth's disappearance, then just nine months later computer graduate Lola Shenkoya, then 27, went missing from the same road after returning home from work.
Locked out of the house because her sister had the key, Lola is said to have caught the E2 bus to Haven Green and got out by Burger King by Ealing Broadway Tube
station.
She was never seen again, and her bank accounts have never been touched.
Serial rapist Andrezej Kunowski, who was dubbed 'The Beast', was grilled by police due to his history of operating in the area.
The now deceased monster was jailed for raping a student, and is believed to have committed at least 17 rapes in Poland. He murdered 12-year-old Katerina Koneva in her west London home when she returned home from school.
A lack of evidence meant he was never charged over Elizabeth and Lola's disappearances. They remain missing to this day.
