Vic deaf murder accused made admissions

A deaf woman accused of murdering her ex-boyfriend admitted to a friend that she, her boyfriend and another man pushed him off a balcony, a court has heard.

The same three were also seen using sign language planning to kill a man almost a year earlier, the court heard.

Georgia Fields, 19, Warwick Toohey, 37, and Jake Fairest, 26, have been charged with murdering Robert Wright, 36, who died in hospital after he fell from his second storey Ringwood balcony in January.

Train driver Elise Clausen told a committal hearing on Tuesday Fields admitted being involved in the death.

Fields initially blamed Fairest for pushing Mr Wright over the balcony before saying all three were involved during a Facebook conversation with Ms Clausen, the court heard.

Fields initially said, "Jake did push him and we was accident (sic) to be involved," Ms Clausen told the court.

After further questioning, Fields went on to say, "Yes, we did but it was accident (sic) but no more now."

When Ms Clausen put to Fields that she, Toohey and Fairest had all pushed Mr Wright off the balcony, Fields replied "yes".

The court had previously heard Fields had been involved with both Mr Wright and Toohey, who were flatmates, and that the men "shared" her before the relationship between Mr Wright and Fields ended.

Another witness, Michelle O'Neill, who knew the trio from the Victorian College for the Deaf, said she witnessed them planning to kill a man in February last year.

All three of the co-accused are deaf and communicate via Auslan sign language.

Ms O'Neill said she saw them on a train "talking about killing a man" in her statement to police, which has been tendered in court.

"They were planning on killing a man," Ms O'Neill said in her statement.

"They were planning on having a pole and hitting him on the head when he was asleep."

The committal hearing continues.
