“Impossible” is not a word scientists like to use. But during his fifth, and last day on the stand, forensic scientist Scott Egan got as close as possible to that definite term.

He described a potential contamination of Bradley Edwards’ DNA into samples of Ciara Glennon’s fingernails as being highly unlikely, going as far as saying the two were tested 13-months apart.

Defence lawyer Damien Cripps says in this podcast, it’s looking like this is a full stop on this contamination theory, and the defence would have to start looking elsewhere for other ways they can weaken the prosecution’s case.

During re-examination, the prosecution asked just one question: In that 13-month period between the two samples being tested at PathWest, how many times would the lab have been cleaned?

He replied, with a slight smirk as Tim Clarke observed, “hundreds, if not thousands of times.”

Join Nat, Tim and Damien as they take you through day 57, and the last day for week 13, as the court takes a day off to prepare for new witnesses.
