POLICE say there is "every likelihood" a local resident could be behind the disappearance of Boronia girl Siriyakorn 'Bung' Siriboon.
Detective Inspector John Potter of the homicide squad announced that police had received new information that Bung was seen just 130 metres from the entrance of Boronia Heights
Secondary College at 8.55am the day she disappeared last year.
He said the information suggested Bung walked along Hardcourt Road, crossed Paisley Avenue and headed towards Moncoe Street.
Bung's parents confirmed this was Bung's normal route to the school.
Inspector Potter said Moncoe Street was the rear entrance of the school and was not as frequently used.
"Obviously, something has happened in that short distance to get to school."
The time of the sighting also confirmed that Bung had left her home on June 2 intending to go to school. Inspector Potter said this led police to believe there was "every likelihood that the person [who took Bung] is a local".
He hoped the new information would help people refocus on what they saw that morning.
"We believe this is a case that will be solved by locals," he said.
Police will continue doorknocking the surrounding streets and reviewing the registered sex offenders list.
They want to hear from anyone who lives, works or was near the three Boronia streets on June 2 last year.
