Cpl. Chris Dibblee was the first officer from the Emergency Response Team (ERT) to enter the room where Randy Crosson was holding his girlfriend, Nona Marnie McEwan, at knifepoint on the morning of March 29, 2019.

含羞草研究社淭o say it was high risk would be an understatement,含羞草研究社� Dibblee said during testimony at a coroner含羞草研究社檚 inquest Thursday (April 18).

Dibblee and Const. Jordan MacWilliams, another member of the entry team, testified separately at the inquest into the deaths of McEwan, 45, and her boyfriend Crosson, 48. The inquest, which started on Tuesday (April 16), is underway at Coroners含羞草研究社� Court in Burnaby.

At the time of entry, the primary entry team, called 含羞草研究社淏ravo,含羞草研究社� included Dibblee, MacWilliams, Const. Luke Johnston, Const. Darcy Rowe, Const. Andrew Michaud, and Const. Brent Wantke.

Dibblee testified that each ERT member is trained to make a risk assessment before and during calls. In most cases, the risk assessment decreases as the call progresses, but in this case the risk increased as police gathered more information, Dibblee said.

含羞草研究社榊ou have one hour含羞草研究社�: ERT members expedited response

As the hostage situation progressed, MacWilliams was an outside deck with four other members of the Bravo team when the robot operator relayed the message that they had heard a male voice say, 含羞草研究社淵ou have one hour.含羞草研究社�

含羞草研究社淲e took that as a timeline, and that generated a request from command for us to expedite getting our deliberate action in place to try and attempt the hostage rescue,含羞草研究社� MacWilliams said.

During that time, MacWilliams heard a man from inside the closed room yell, 含羞草研究社淵ou have five f含羞草研究社�-ing minutes.含羞草研究社�

含羞草研究社淪o I was very concerned,含羞草研究社� MacWilliams said. 含羞草研究社淚 believed when he said that that meant that he was going to kill her if we didn含羞草研究社檛 do something in those five minutes.含羞草研究社�

Michaud than radioed to have Dibblee join the Bravo team upstairs and to bring a ballistic shield, MacWilliams recalled.

Dibblee moved to the front of the Bravo team, armed with a pistol, hard body armour and a ballistic shield.

Johnston placed an explosive charge on the door to the bedroom where McEwan and Crossson were believed to be.

MacWilliams heard Cpl. Frank Penney, yell the go word, 含羞草研究社渓ighting, lighting, lighting.含羞草研究社�

Johnston initiated the charge from a short distance away and yelled 含羞草研究社渇ire in the hole.含羞草研究社�

As the charge went the Bravo team moved towards the door.

Dibblee said, 含羞草研究社淎s I reached the threshold of the door, I can see that there is what I perceived as a lethal threat, meaning there含羞草研究社檚 a person who said that somebody含羞草研究社檚 going to kill this woman.含羞草研究社�

Crosson was using McEwan as a 含羞草研究社榟uman shield含羞草研究社�: police

Both Dibblee and MacWilliams testified that they could see Crosson and McEwan lying on their backs on the bed, with McEwan being held on top of Crosson, facing the door. Crosson was using McEwan as what Dibblee and the police refer to as a 含羞草研究社渉uman shield.含羞草研究社�

Both officers said that they could see Crosson holding a knife to McEwan含羞草研究社檚 neck and a pistol in other hand that he was waving around.

Dibblee called out 含羞草研究社渉uman shield,含羞草研究社� so the ERT members behind him were made aware.

MacWilliams threw the flashbang grenade toward the corner where Crosson and McEwan were.

Upon entering the room, Dibblee tripped over the clutter and debris that was in front of the entrance to the room.

When he got to his feet, he could see that Crosson and McEwan had not moved.

Dibblee moved into a different part of the room so his teammates had space to enter.

含羞草研究社淎t that time, he still had the knife in one hand and the gun in the other. I felt that the threat hadn含羞草研究社檛 changed, and as I was approaching him, I already knew from the door that unless something changes, I have to shoot him to stop him,含羞草研究社� Dibblee said.

During this time, Dibblee saw 含羞草研究社渘o indication of surrender.含羞草研究社�

Dibblee said he recalled being the first to fire, and more than once before any other rounds were fired.

含羞草研究社淚 was the closest, obviously being the first person in the room, I was the closest to them, and I don含羞草研究社檛 recall hearing any shooting before I shot,含羞草研究社� Dibblee said.

During this time, other Bravo team members entered the room.

MacWilliams testified the officers含羞草研究社� actions had no effect on Crosson含羞草研究社檚 behaviour.

含羞草研究社淗e still had the gun in his hand pointed towards us,含羞草研究社� MacWilliams said.

MacWilliams shot two more rounds, until Crosson 含羞草研究社渟lumped against the wall.含羞草研究社�

MacWilliams and Dibblee stopped shooting when they saw that Crosson was no longer a threat. Dibblee shouted, 含羞草研究社渉e含羞草研究社檚 down,含羞草研究社� to let other members of the team know.

The team then shifted to 含羞草研究社渁ssessing to recovering Ms. McEawn and assessing her for any injuries.含羞草研究社�

含羞草研究社淭hat would have included assessing Mr. Crosson for injuries; as I mentioned, his injuries were such that there was not going to be anything that we could medically provide for him.含羞草研究社�

Dibblee was one of several medics that attempted to provide life-saving care to McEwan.

The inquest is underway on the 20th floor of Metrotower II, with coroner Margaret Janzen presiding. She and a jury are hearing evidence from witnesses under oath.

The jury may make recommendations aimed at preventing deaths under similar circumstances but not any finding of legal responsibility.
