An expert from Ottawa testified he discovered gunshot residue on the outside of a hat that the Crown contends was worn by Brandon Phillips the night of a fatal 2015 armed robbery at a St. John's hotel.

Nigel Hearns, a gunshot residue specialist from the RCMP's crime lab, told a Supreme Court jury Friday that the front of a hat sent from the Royal Newfoundland Constabulary tested positive for gunshot residue.

Hearns explained to the 12-person jury that fibres in clothing will — in some cases — hold gunshot residue for years if it is handled properly.

"If you don't wash it, it stays," he said.

The court has heard that RNC Const. Lisa Anderson found the hat around 10:30 a.m. on Oct. 4, 2015. It was nearly 10 and a half hours after bar patron Larry Wellman was shot.

Anderson located the hat on Forest Avenue, which runs behind the Captain's Quarters Hotel, which faces King's Bridge Road.

During cross-examination Thursday, defence lawyer Jeff Brace questioned it if was possible that one of the RNC officers who had been at the crime scene could have transferred gunshot residue to the hat.

Hearns told the jury Friday that scenario is unlikely if clean gloves were used to collect the evidence.

Phillips, 29, is charged in the shooting death of Wellman, 63, on Oct. 3, 2015 during an armed robbery at the Captain's Quarters.

The Crown alleges Phillips brought a sawed-off shotgun to the hotel in order to rob it.

Hearns will be cross-examined Friday afternoon.
