Breaking:Lamarre-Condon describes the moment Jesse Baird died
Lamarre-Condon has outlined the way he claims Jesse Baird was killed.
He claimed he found Baird holding a knife and masking tape.
'He started yelling "we're getting robbed", "we're getting robbed",' he said.
Lamarre Condon claimed Baird could not tell it was him.
'He had the knife, he dropped the tape, and he lunged at me. I immediately grabbed ... his right hand with my left hand and my right hand to pull the knife away from me, and I said, "Jesse, it's Beau, it's Beau, it's me. Calm the f**k down!"
'And he wouldn't register what I was saying ... His adrenaline was through the roof.'
Lamarre-Condon claimed he repeatedly told Baird to drop the knife, which he claimed was by then at his throat.
The alleged killer claimed he feared for his life as Baird slashed open his shirt with the knife.
'I didn't want to kill him,' he said.
Lammare-Condon claimed his police training forced him to shoot him in the chest.
'I guess it's just my instinct. Police training, as police officers, we are trained to shoot people at the centre body mass to kill a person, to stop the threat, and to kill them. I did not want to do this to Jesse.'
He claimed he aimed at Baird's right shoulder, which forced the knife out of Baird's hand.

Beau Lamarre-Condon 'passed out' after alleged double murders
Lamarre-Condon claimed he had an 'out of body experience' after he allegedly murdered two men.
'I just remember hyperventilating, and this is when it felt like an out of body experience,' he said.
'It was like I was floating above my body and looking down at myself from third person, and everything around me just didn't seem real.
'It was like ... someone else watching myself, and I just remember coming in and out of my body like I was disassociated from my body, and then I could see myself hyperventilating and having a panic attack, and then I went to the couch, lay down, and I passed out for a period of time.'

Breaking:The moment Luke Davies died, according to his alleged killer: 'My hand did not touch the gun'
Lamarre-Condon claimed Luke Davies died by shooting himself as the policeman tried to disarm him.
'He put his left index finger on the trigger, and I thought he was going to shoot me. So I watched the gun the entire time. I did not get my eyes off the gun,' Lamarre Condon said.
The former cop said he watched the bullet leave the back of Davies' skull and lodge into the bedroom door.
It is the same door police allege Lamarre-Condon shot Davies through to eliminate him as a witness to the alleged murder of Jesse Baird.
'My hand did not touch the gun in this movement,' he claimed.

Luke Davies threatened to shoot Beau Lamarre-Condon as the former cop tried to save Jesse Baird's life, jury told
Lamarre-Condon claimed he was trying to save the life of Jesse Baird when Luke Davies appeared holding his firearm.
'I said, "Please don't shoot me. I'm not here to hurt you. You can take the gun and leave. Get out!",' he claimed.
'And I was screaming because obviously my ears were ringing out, so I couldn't hear a thing.
'And that was to pretty much say to Luke that I'm not a threat. You can keep my gun. Take it. Just get out of the house. I'm not a threat. I'm not here to hurt you. And that's when he raised the gun towards my head, and that's when he said "f*** off"'.
Lamarre-Condon claimed his police training kicked in again as Davies threatened to shoot him.
'I immediately thought, "f**k, he's gonna fire the gun." He just told me, "I'm gonna f***ing shoot you." Now he's raising the gun towards my head, and that's when again my police training kicked in,' he said.

Lamarre-Condon claimed he tried to save Jesse Baird after shooting him through the head
Lamarre-Condon claims to have tried to save the life of Jesse Baird after shooting him dead.
'I couldn't tell that it was a the bullet that had gone through his head. It just looked like possibly it had scraped the side of his head,' he said.
'So I get up, I get into the kneeling position, I look at Jesse, and again it's now I'm into police mode. It's what do.'
Lammare-Condon claimed he checked for a pulse and pleaded for Baird to wake up.
'I started saying, "Jesse, Jesse, can you hear me? Please wake up. Please squeeze my hand if you can hear me.",'
He claimed to have put Baird into the recovery position, when he said Luke Davies approached carrying his gun.

Lamarre-Condon claims he accidentally killed Jesse Baird, again admitting he pulled the trigger that killed his former lover
Lamarre-Condon has again admitted to the manslaughter of Jesse Baird.
'My finger was on the trigger, not Jesse's, and I must be truthful, and I must take accountability that I'm responsible for. But it wasn't intentional,' he said, wiping his eyes.
'His hand was not on the trigger; it was my fault. And I've said from the start, I am guilty of manslaughter, and I'm responsible for his death.
'But it wasn't intentional, and this is where we were either falling to the ground, or as we impacted the ground, the gun discharged.'

Lamarre-Condon claimed he wanted to get his surfboard out of Jesse Baird's ute on day he allegedly murdered him and Luke Davies
Lamarre-Condon has been taken to the day his alleged victims died.
'I wanted to be 110 percent certain, like I was going into that house to get my stuff, that no-one was home,' he said.
The court heard he watched as Baird's housemates left his home, telling the jury he believed Baird was already out.
Lamarre-Condon claimed he had been concerned Baird would get an intervention order placed on him if he came to the house 'because Jesse told me please refrain from contacting me,' he said.
He told the court he parked his car and noticed an Uber Eats rider nearby.
Not wanting to leave his police-issued gun in the car, he took it with him.
'If someone broke into in my car and stole my gun, I'd be in a lot of s***,' he said.
Enroute to the cafe Lamarre-Condon said he swiped the Uber Eats rider's gear.
Breaking down yet again into tears, Lamarre-Condon outlined his plan.
'I had the thought process off, If I was to put on this helmet, a motorcycle outfit, and look like a delivery driver, I could knock on Jesse's door, and if he answered the door, he wouldn't be able to see my face,' he said.
'I would look like an Uber Eats driver, and that way, I couldn't be falsely accused of harassment ... I could just say wrong address walk away without any verbal argument or confrontation with Jesse.
'And if he wasn't home, I could enter with a spare key that he got cut for me and go in and get my belongings.'

Lamarre-Condon describes dressing up as Uber Eats rider before going to Jesse Baird's home
Lamarre-Condon claimed the door of Jesse Baird's home was open when he initially attended.
Not wanting to go inside, he claimed to have backed off and gone for a walk.
On his return, the door was still open and he knocked three times.
'I pushed open the door further, but with my hand, I opened fully. I stepped into the entryway and I yelled out "hello" in a really loud voice, and I got no response. And I couldn't hear or see anyone in the house,' he said.
He told the court he snooped about before investigating some storage boxes in the hallway.
Baird had been in the process of moving out of the Paddington home when he was allegedly killed.
Lamarre-Condon said he noticed more storage boxes in the kitchen and proceeded there.
'I saw someone's arm, their left arm, push up into the back door like they were just opening the door and entering the property. I immediately ran upstairs,' he claimed.
The court heard he ran into the bedroom of Baird's housemate where he hid behind the bed, still wearing the helmet.
Lamarre-Condon claimed he thought he heard someone calling the police, but was unsure who it was.
'After two minutes, I heard a door shut. So I assumed that it must have just been someone on the phone, and they were going to leave, and they did leave by shutting the door.'
He then proceeded downstairs.

Lamarre-Condon cries again and again recalling conversation with his mum and plans to leave the force
Lamarre-Condon has continued to cry about bully-boy cops, wiping tears from his eyes with a dirty tissue.
The latest tears came while talking about a conversation with his mum on the phone after the alleged murders.
'My mum could tell that something wasn't right in regards to me being emotional,' he said.,
'I had told her that I just essentially mentally wasn't feeling okay because of work. Again, my mum understands this because she was a police officer. She's been through similar experiences, and then we went on to discuss (an alleged bully).'
He told the court his mum advised him to quit the police force for good.
'One of the things my mum said was while we were driving there, is you just need to keep yourself busy and in a positive mindset and make plans with friends to just see friends,' he said.
Lamarre-Condon said he told him mum he planned to kill himself.
'My mum then said she's not letting me leave her sight until I tell her for a fact that I'm going to go off work permanently, and she said that I have to go see a psychiatrist and any medication that I'm given, I have to take it, or she's not letting me leave and should put me on a psychiatrist,' he said.
Lamarre-Condon said he finally agreed on the morning of February 19 to take time off work.
'So the plan was to essentially go get my belongings back before returning my arms,' he said.
'Then I was going to go about my day, meet up with my friends for dinner. Yeah, it was going to be a normal day.'

Lamarre-Condon breaks down again about his rotten lot in life at the hands of bullying cop colleagues
Beau Lamarre-Condon has again complained about his work conditions leading up to the alleged murders of two men.
Choking back tears, Lamarre-Condon again claimed his treatment by a former colleague had pushed him to the brink.
'If I was going to have to work with him again on a day-to-day basis as a direct supervisor, and have to go through that tormenting and harassment and bullying on a day-to-day basis, I would have rather been dead than alive, and that was my mindset at the time,' he told the court.
Lamarre-Condon began his evidence on Thursday complaining about colleagues he claimed were homophobic bullies.
23:34
Lamarre-Condon was 'joking' about sticking a friend in a surfboard bag
Lamarre-Condon said a comment about sticking a mate in a surfboard bag, days before the alleged murders, was simply 'dark humour'.
'Would you fit in this?' he asked the mate, who cannot be named.
Lamarre-Condon dismissed the comment as a joke.
'(He) wanted to become a police officer, so I made a dark humour joke about: "Oh, how quick do you think my colleagues would be if I put you in this ... and dragged you out of the store, how quick do you think they would turn up?",' he told the jury.
'And then I made a dark sense of humour joke about when you become a cop, you'll start to see things differently.'
Lamarre-Condon is accused of dumping the bodies of his alleged victims in surfboard bags.

Lamarre-Condon is again told to slow down while giving evidence
Beau Lamarre-Condon has been told to speak more slowly while answering questions.
It is the second time the former police officer has been told to drop the pace of his responses to questions.
Everything Lamarre-Condon says needs to be transcribed by court stenographers, who are known to have freakish abilities to transcribe what happens in a court room in real time.
Despite the direction by his own barrister, Lamarre-Condon's pace has not appeared to have been reduced.
