A MELBOURNE man has pleaded guilty to murdering his wife in front of their young son after an argument about Facebook.
Ron Felicite fatally stabbed his wife Marie multiple times in the neck in the kitchen of the couple's Narre Warren home in August last year.
Their four-year-old son was in the house and is believed to have witnessed the killing, the Victorian Supreme Court heard.
The previous day, Felicite had argued with his wife about her relationship with a man named Dino, whom she had met on the internet.
The court heard Ms Felicite called police to their home during the argument, but it was determined the situation did not require police action.
Later that day, the couple attended counselling where Ms Felicite said she had feelings for the man she met on the internet and no longer loved Felicite as a husband.
Prior to the stabbing, Felicite confronted his wife about her communication on Facebook with her cousin about Dino.
On Friday, Felicite, 28, pleaded guilty to murdering his wife.
His pre-sentence hearing continues on Monday.
