Quirke trial: So how did Bobby Ryan die?

Two eminent pathologists clashed on the most likely cause of Bobby Ryan's death with one saying he probably suffered blows from a blunt instrument and the other suggesting he was more likely struck by a vehicle.

As part of the prosecution case an entomologist (insect expert) gave evidence that the body, which was sealed in an airtight tank, was subjected to a single insect infestation in the weeks before the accused man Patrick Quirke told gardai he discovered the body.
