Teen girls spared jail for filming videos of manslaughter

Two teenage women who filmed "reprehensible" videos of their friends engaged in threats, torture and assault that led to a man's death have been spared jail terms.

Cian English, 19, died trying to escape the three men in a Gold Coast apartment in May 2020 after they wrongly accused him of stealing prescription drugs and stabbed him with a knife.

Jason Ryan Knowles, 25, Lachlan Paul Soper-Lagas, 21 and Hayden Paul Kratzmann, 23 were originally charged with murder but in September this year each pleaded guilty to manslaughter.

The two women, aged 16 at the time, both pleaded guilty in Brisbane Supreme Court on Tuesday to torture and armed robbery, which was later depicted in videos posted to social media with emojis and obscene captions added.

The 16-year-olds posted 15 brief videos lasting between a few seconds and less than a minute, with the first filmed at 2.15am and showed Mr English's friend being stripped and searched for drugs before Mr English was threatened with a knife and punched as he tried to intervene.

One of the girls was filmed telling Mr English to wipe the floor with a tissue, saying "It is literally not clean, get all the blood off".

The other was filmed joining in yelling a countdown at Mr English's friend over the time he had to hand over his phone or otherwise get stabbed.

Chief Justice Helen Bowskill sentenced Knowles and Kratzmann to nine and a-half years and Soper-Lagas to eight years in September.

Mr English had joined the group hours before after they started partying in the apartment above his own and might have been trying to climb back down to his own accommodation before his fatal fall.

The videos also depicted one of the girls looking over the balcony after Mr English had fallen.

Crown prosecutor Caroline Marco said the women had endorsed the crimes of their three male co-offenders and directly participated in some of them.

Mr English's mother Siobhan on Tuesday read to the court her victim impact statement and said her life had been changed forever in the blink of an eye.

"I still can't even bear to think about how he died, how he struggled, to contemplate how he suffered. Thinking about it destroys a little part of me every time," Mrs English said.

A barrister for one of the women, Martin Longhurst, said his client was "genuinely remorseful" and suffered nightmares and flashbacks of her offending.

Justice Peter Applegarth said the women had shown cruelty and indifference to the two men, including the "disgusting" order to Mr English to clean up his own blood.

"The uploading of the videos to social media was absolutely reprehensible ... your immediate post-offence conduct showed no signs of remorse," Justice Applegarth said.

Justice Applegarth said it was appropriate to sentence both women to two-year probation orders and with no convictions recorded to assist them to continue mental health and drug abuse rehabilitation.
