Miller, the aunt of then chief commissioner Mick Miller, left for church on Sunday, August 10, 1980, intending to take a tram along High Street, Glen Iris.
Eighteen days later, Headland, 14, was heading to catch the bus at Princes Street, Berwick, to the Fountain Gate shopping complex.
Sargent disappeared, likely along the Princes Highway, after intending to catch a bus to the Dandenong office of the Commonwealth Employment Service on October 6, 1980.
It would take a further two years to find a fourth body on the other side of Brew Road: Stephenson, who was abducted from Northcote in November 1980.
Two further murders occurred nearby. Rooke, 59, went missing on May 30, 1980 after telling friends she was catching a bus on Frankston-Dandenong Road to a local shopping centre. Her body was found on July 5, 1980, hidden in scrub near Skye Road, Frankston.
Summers, 55, was to have caught a bus on the Frankston-Dandenong Road on October 9, 1981. On November 22, 1981, her body was found in scrub beside Skye Road.
Janman told police he offered women lifts on the Frankston-Dandenong Road, where Rooke and Summers disappeared in 1980 and 1981, because he was a friendly guy and just wanted to help people.
When he drove with the police along the road, Janman pointed to nine bus stops where he offered women lifts. Two of the stops were where Rooke and Summers were waiting when they disappeared.
He lived at Garfield, near the Tynong North murder ground, for many years.
Janman had repeatedly declared his innocence to police and to the media. He told A Current Affair in 2018 that he had “never hated a person or disliked them enough to wish them dead and take their life.”
There has never been any hard evidence linking him to any of the murders.
