Mentally ill man sentenced to life in detention

A mentally ill man will spend life in detention after shooting dead three people.

The Supreme Court today ordered Donato Anthony Corbo be detained at mentally ill facility James Nash House for life.

He was found not guilty due to mental incompetence after killing South African immigrant Luc Mombers and his in-laws at Hectorville in 2011.

Mr Mombers' wife Rika and teenage son Marcel survived. Two police officers who attended the premises were injured.

Corbo was found not guilty of three counts of murder, two of attempted murder and one of aggravated threatening life.

Justice Michael David said: "The most disturbing thing about this whole tragedy is how this man had a gun in his psychiatric condition."

Victim impact

Rika Mombers said she still cried every day since her husband was killed.

"Luc and I were happily married for 19 years and that was taken away in a moment," she said.

"I feel like a robot most of the time," she said.

"I hate the feeling of people feeling sorry for me.

"The shooting played over and over in my mind. I cry every day. I'm scared every day. I hate guns and the noises they make."

A family friend, Johan Grove told the court that South Africans would think twice before coming to Australia.

"You're a bastard for murdering my friend and his parents-in-law with him.

"You have taken away the dreams of Luc's family. Luc wanted to give his kids everything. They had left South Africa because of crime.

"I could not imagine the fear and pain they would have gone through."

His wife Mirella said she was shocked such a thing had happened in Adelaide.

"I kept thinking this happens in South Africa, but not in Adelaide," she said.

"Mr Corbo, in your moment of rage and madness you destroyed a beautiful family."
