State Crime Operations Commander Rod Wilde joined Liam Bartlett in the first broadcast of the 6PR Morning program's new cold cases series.

They discussed the recent cold case of 11-year-old Rockingham boy Gerard Ross, who went missing on October 14, 1997.

His body was found two weeks later on October 28 and, despite 4700 witnesses being interviewed across 25 years, information is still being sought.
