'I want to come home now': Teenager texted mother on night of her death

An Ipswich man accused of violently beating his partner before telling police she was critically injured by "misadventure" after jumping on the bed, has pleaded not guilty to her murder.

Michael Kurt Pringle is facing trial in the Supreme Court in Brisbane charged over the death of Krystle Monks.

A jury has heard the 19-year-old was taken to hospital in February 2023 and died the following day after her life support was withdrawn by family.

On Monday Crown prosecutor Nathan Crane told the jury it will be alleged her death was caused by a "protracted" and "violent assault" carried out by Mr Pringle at his Bundamba home.

"She sustained … blows to the head," he said.

"You can't see the traumatic brain injury that followed."

However, Mr Crane told the jury they will see evidence she allegedly suffered more than 60 "external injuries", and she was "peppered with bruising and abrasions".

"They are the markers of the violence that was perpetrated upon Krystle," he said.

The jury heard before Mr Pringle called emergency services to report his partner had fainted, he made three google searches, including "can people faint".

He told the Triple Zero (000) operator and later police, Ms Monks had been drinking and injured herself, the jury heard.

Mr Crane told the jury there will be evidence played to the court, in which Mr Pringle claims her death was the result of "misadventure".

"Mr Pringle says … Kyrstle Monks jumped on the bed, fell off the bed and hit her head on the dresser," he said

"That's the explanation ultimately."

'Relationship of animosity'

The jury heard they will also be shown text messages between the pair earlier in the night, in which they were arguing about photographs of Ms Monks.

Mr Crane told the jury these messages demonstrated jealousy from Mr Pringle, and a "motive to be violent" towards her.

"You'll hear that Mr Pringle called her, within that half an hour on the text messages, a liar, a dog, a s**t, a rat, scum, and a c**t," he said.

Mr Crane told the jury it was "a relationship of animosity".

"You will see those words repeatedly in the course of this trial because those are the words he often used towards his partner over the preceding months."

The jury also heard on the same night she texted her mother to say, "I want to come home now".

This was after her mother had told her if she did not feel safe, she should reach out, the jury heard.

Several witnesses are expected to give evidence, which the jury heard will allegedly establish Mr Pringle had been physically violent to Ms Monks repeatedly throughout their short relationship.

The jury heard one woman set to testify did not know the couple but allegedly witnessed Mr Pringle punching Ms Monks while driving in his car, and she reported it to police.

Following this, the jury heard officers attended Mr Pringle's home and he denied assaulting her, but later messaged Ms Monks and said "apparently someone seen me hitting you lol".

Ms Monks co-workers and a neighbour of Mr Pringle's are also set to take the witness stand.

The trial is expected to run for two weeks.
