AS about 250 text messages are fired back and forth, the intent becomes brutally clear.

The messages, between two young Queensland men, allegedly reveal a wicked plan to kill a friend they “can’t be bothered with him anymore” because “he’s so boring”.

The frightening texts were contained in court documents obtained by The Courier-Mail and show a detailed conversation between Max Peter Smith and Kyle Mitchell Dumesny as they purportedly hatch a plan to kill Jake Lasker, when they were all aged 19.

Smith, now 21, has admitted to murdering Mr Lasker in a stabbing attack at his Toowoomba home on November 7, 2012.

After a few frenzied moments, Mr Lasker was dead — covered in 102 wounds to his neck, head and body.

Smith was jailed for life for the murder in November last year.

His alleged accomplice, Dumesny, was charged with murder last year and is yet to face court. He didn’t attack Mr Lasker and wasn’t in the room when he died, but prosecutors will allege he encouraged the deadly attack.

Much of the case against Dumesny is likely to hinge on the text exchange with Smith. The messages began on November 1 and ended a week later when Mr Lasker was attacked in his bedroom.

The evil plan began when Smith asked Dumesny: “Can we kill him im just sick of it all (sic)”. Dumesny replied with “*evil grin*”.

Shortly after, Smith began to discuss specifics.

“So how do we kill him lure him out drive away then kill or do a stealth at his house (sic),” a message from Smith’s phone read on November 1.

A minute later, Dumesny allegedly replied: “Lure him …. How do we get his stuff.”

In later days, they talk of a way to kill Mr Lasker, including pushing from a cliff and running him over, and burning him alive.

A text message from Smith’s phone read: “burn house down blame on gas some other leak or make them disappear say like went to the shop and never came back. ive got it all planned out that includes a plan B and C (sic).”

On November 4, a message from Smith suggested a location: “prince henry drive where is a cliff we can push him off (sic).”

Later that day, however, the conversation again turned to stabbing as the preferred method of killing.

“I’m getting a bigger knife,” Smith wrote, and then: “Bigger better more confidence.” Dumesny’s reply to those was initially “lol” and then “cool”.

In the final hours before the murder, Smith asked Dumesny if he would come over to help pack up Mr Lasker’s belongings. This followed a lengthy exchange about which of his belongings they could sell to make money.

In chilling detail, Smith said he may have to also kill Mr Lasker’s mother and talks about how he’s prepared so he doesn’t get the victim’s blood on him: “I’m bout to do it I have rubber gloves on also ill need to take out his mom so I can take the car (sic).”

Dumensy allegedly said he felt uncomfortable with blood and left the room shortly after Smith texted that he was “getting ready for it”.

In his police interview, a transcript which was obtained by the Courier Mail, Smith spoke openly about committing the murder in cold blood.

He had been playing Xbox with Mr Lasker when he began to stab him.

“When I was doing this, Jake was trying to defend himself but pretty poorly,” Smith told police in the statement.

Smith has now provided evidence against Dumesny, saying in a police statement that Dumesny had encouraged him to kill the victim in the days before the attack.

Dumesny claimed he heard words to the effect of “What are you doing? Don’t do it. Stop, please, stop.”

When he was first interviewed by police Dumesny claimed to believe that Smith had not been serious about killing the victim.

However, Smith has disputed that account, telling police after he was sentenced that the alleged accomplice “never really gave me any indication that he thought I was joking”.

Police charged Dumesny with murder in May this year.

With his initial co-operation, Dumesny became a key Crown witness. But now, after he too has been charged with murder, Smith’s evidence against him could prove crucial to the prosecution case against him.

At the Brisbane Supreme Court yesterday, where Dumesny sought bail, Justice David Boddice asked why it had taken so long to charge Dumesny.

“When you read the text messages, you could say the police had a strong case against (Dumesny) — at least in respect to it being a conspiracy, or certainly being a party,” Justice Boddice said. “But it seems police didn’t take (the text messages) seriously at that time (in 2012).

“They used the applicant as a person who could provide evidence against Smith, who had been charged with murder. And after Smith pleads guilty, they turn around and charge the applicant.”

Justice Boddice adjourned the application until after Dumesny’s committal hearing fearing Smith could give false evidence as revenge for Dumesny testifying against him.

The case returns to court for the committal hearing next month.
