In a colossal technical error, it has been found that DNA evidence has being bungled in dozens of Queensland crimes, including the murder of pregnant Logan woman Joan Ryther.
Queensland authorities confirmed the “minor miscode” had affected DNA likelihood ratios in 60 cases, prompting defence lawyers to raise doubts about other results.
“Clearly the code they have relied on historically has been faulty,” said high-profile lawyer Michael Bosscher, who is representing the accused in the Ryther case.
“We’re being asked to be assured that all of the faults have been rectified. It casts doubt across the board in relation to DNA probability statistics.”
