Good post. One thing I definitely think is that the killing of Gerard Ross was not the perpetrator’s only crime in their lifetime. It is too vicious and brutal to be something isolated and random in their lives. They must have a criminal history before and/or after.Perhaps the person who killed Gerard is in plain sight, listed upon a sexual offender’s register – thinking he may have committed a sexual crime after 1997 - involving a boy aged between 8-12. As there were other incidents of lifts being offered within the Rockingham area it’s likely the offender was local to Rockingham or a nearby suburb. Rockingham is the largest city within a wide radius, so the POI may have been drawn for work or shopping.
Thinking if GRs killer was a pedophile, the abductor may not have been able to go through with an intended evil act. One example, and nothing to do with GRs killer, is NSWs Phillip Wayne Lett who abducted a 6-year-old for intentions of pedophilia, but couldn’t go through with the act – he was aged 32. Instead, Lett brutally killed the young boy and left him. A heinous NSW crime occurring in 1992 7News
Lots of children have been offered lifts whilst waiting at a bus stop. I suppose it’s the perfect opportunity for someone to stop and offer a lift.
