Deaf Vic man could stand trial for murder

A deaf man accused of murdering his Melbourne flatmate could stand trial if legal proceedings are modified to help him understand what is going on, a psychologist says.

Profoundly deaf man Warrick Toohey, 37, has been charged with the murder of 36-year-old Robert Wright, with whom he had allegedly shared a girlfriend.

Toohey and two other profoundly deaf people were charged with murder last year after Mr Wright fell to his death from the balcony of a Ringwood flat in January 2015.

Clinical psychologist Chris Drake told the Victorian Supreme Court that Toohey would be fit to stand trial if more regular breaks were available and information was repeated or rephrased so he could understand what was being said.

"I believe he is fit to stand trial," Dr Drake said on Friday.

Dr Drake said Toohey was mildly intellectually disabled, but was able to understand statements or questions that confused him if they were rephrased in another way.

The trial by jury to decide whether Toohey is fit to be tried for murder will continue over three days.
