For the first time in the courtroom, the nine loud gunshots rang out.

They were repeated several times as the Crown played video and audio recordings taken on the night Const. James Forcillo shot Sammy Yatim on an empty Dundas streetcar shortly after midnight on July 27, 2013.

Forcillo has pleaded not guilty to second-degree murder and attempted murder. The jury must decide whether his use of lethal force was reasonable and necessary, the Crown has said.

A never-before-heard audio recording was played to the jury Thursday, revealing part of the exchange between Forcillo and Yatim before shots are fired.

The audio comes from a microphone on the streetcar that is triggered in emergencies and begins transmitting to TTC dispatch. The recording played to the jury captures part of what is occurring on the streetcar and the comments of the TTC dispatcher listening.

“Get the f—k out of here, all of you,” Yatim is heard yelling after the passengers who have fled the streetcar. “Run. Don’t walk.”

This is moments after he slashed a knife towards a young woman sitting near him at the back of the streetcar, prompting the panicked flight of all passengers on board.

The streetcar driver is still in his seat and Yatim asks him for a phone to call his dad. The streetcar driver’s response is unclear. Yatim says: “There is something going on. I don’t know what the f—k it is.”

Yatim heads to the back of the streetcar to get his backpack and when he notices the streetcar driver getting off he says: “Hey, hey, hey, hey driver where you going?”

The streetcar driver stops, one foot on the road, the other on the bottom of the streetcar step.

Yatim tells him to go then says: “Get settled. I’m not gonna hold you as a hostage.”

The streetcar driver climbs back up the steps and Yatim sits down in the front passenger seat.

The streetcar driver appears to be speaking with Yatim but the audio cuts out for several seconds. Yatim suddenly stands and moves towards the driver, knife outstretched. The driver runs off the streetcar.

Seconds later, Forcillo approaches gun drawn and yells: “Drop the knife. Drop the knife.”

Yatim says no.

As Forcillo, and later other officers, continue to command Yatim to drop the knife, Yatim begins calling the officers “p—y.”

“You’re a f—kin’ p—y. And you’re a p—y. Everyone is a p—y.”

Forcillo’s partner Const. Iris Fleckeisen asks Yatim if anyone else is on board. Yatim does not answer - it is unclear if he heard her - and continues to refuse to drop the knife. He takes a few steps backwards.

Fleckeisen says she is getting out of the way. Forcillo says: “We need a sergeant with a Taser.”

Forcillo then tells Yatim: “You take one step in this direction and (unclear) shoot you. I’m telling you right now.”

A male officer says: “Don’t move. Drop it.”

Yatim: “No.”

Male officer: “Drop that knife.”

Yatim takes a step towards the front of the streetcar, where he was standing seconds before. Forcillo fires the first shot. It is 51 seconds past midnight.

Forcillo fires three times. The Crown has said all three bullets hit Yatim, striking him in the spine, upper right arm and fatally in the heart. The shot to the spine left Yatim paralyzed from the mid-chest down, the Crown has said.

Five-and-a-half seconds later Forcillo fires the second burst of six shots. Five of them strike Yatim. As Forcillo shoots, a male officer yells: “Drop the knife.”

The final shot is fired at 12:01:02.

Forcillo holsters his gun and moves towards the streetcar doors, then a male officer yells “Get back.”

Forcillo yells: “Drop the knife. Drop the knife.”

The officer with a Taser gets on the streetcar and says: “drop the knife. Drop it,” before discharging the Taser. He continues to tell Yatim to drop the knife until he steps over and kicks the knife from Yatim’s hand.

The jury has heard that an ambulance was called for Yatim and medical attention provided, but that he died on the streetcar.

In cross-examination of SIU investigator Steven Adam, defence lawyer Peter Brauti emphasized that Yatim had been using “illegal narcotics” and had MDMA (commonly known as ecstasy) in his system.

He also asked Adam how dangerous the illegal switchblade that “becomes a deadly weapon with the hit of a button” was. Adam agreed that, like all knives, the switchblade was a deadly weapon.

The trial continues.
