At the same time, he admitted he really couldn't see Christine's neck due to her hair being thick and curly, but he said he believed she had blood in her hair.

He also said he tried to de-escalate the situation, telling Joe to drop the knife.

He says then he saw Joe forcefully stab Christine, causing Christine to fall to the ground.

And that's when Brendan said he shot the gun at Joe.

Brendan says he saw a bloody wound on Christine's neck and started applying pressure at this point.

But by this time, Brendan says he noticed Juliana in the room.

He claims he asked her to call 911 and to watch Joe as he tended to Christine.

He said Juliana stepped away to the master bathroom.

And Brendan said he was initially unaware that Juliana got the gun from the safe in the bedroom closet.

Now, this is different than what we heard from Juliana, who said he gave her the gun before leaving the McDonald's that morning, and she kept it in her pocket.

Prosecutor Jenna Sands did not hold back Emery.

She challenged him on his version of the stabbing and of the shooting.

He repeated that he was worried about hitting Christine by mistake.

The prosecutor then asked, well, why didn't he use his handcuffs on Joe after he did shoot him?

And Brendan said he probably should have done that.

Brendan said he brought Juliana and Valerie and their dog to the basement while he moved upstairs to the master bedroom to investigate.

He believes Juliana made that first quick 911 call while she was downstairs in the basement and he was upstairs.

And the defense introduced an expert who testified they identified the dog's whining in a portion of that call.

But he said he did tell Juliana to call 911 later after she came up to the bedroom.

And this was after he had shot Joe Ryan.
