A government ballistic expert was, yesterday, grilled over the origins of three firearms examined in connection with the 2013 Acadia Drive triple-fatal shooting and an addendum report later submitted in the case regarding the results of tests conducted on the weapons.

Under cross-examination by defence attorney Hugh Wildman, the superintendent of police, formerly attached to the Institute of Forensic Science and Legal Medicine, was questioned about how the addendum report came about and what information accompanied the firearms when they were submitted for analysis.

“The addendum is a report that is done – a ballistic report in this case – that speaks to additional evidence or items that have been submitted and additional examinations that were done that were not mentioned in the original certificate,” the witness told the court.
