A MAN WHO was suffering from a mental disorder decapitated his wife after attacking her with knives in their Dublin apartment, a barrister has told a jury at the Central Criminal Court.

The jury was also informed that he was arrested and brought to hospital for his own safety the previous day but was discharged the same evening.

Shane Costelloe SC, for the Director of Public Prosecutions, said the jury will hear that Brazilian native Diego Costa Silva called emergency services and told them that he “thought he had killed his wife”. 

When gardaí arrived, they found Mr Costa Silva’s wife, Fabiola Camara De Campos Silva, with her head “clearly separated from her torso”. 

Counsel also told the jury that two days before Mr Silva attacked his wife, he was arrested for his own safety after being seen jogging around Dublin City Centre ”practically naked” in early November. He was brought to hospital but “unfortunately” he was released the following day, Mr Costelloe said.

He said that the jury of seven men and five women will hear from two forensic consultant psychiatrists called by the defence and prosecution who agree on Mr Silva’s state of mind at the time of the killing.

Counsel also told the jury that the day before Mr Silva attacked his wife, he was arrested for his own safety after being seen jogging on the street “practically naked” in early November. 

He was brought to hospital but “unfortunately he was released that evening,” Mr Costelloe said. 

Diego Costa Silva (35) has pleaded not guilty to the murder of Fabiola Camara De Campos Silva (33) on 4 November, 2021 at Charlestown Place, Finglas, Dublin 11. 

Before the trial began, the jury was told that the issue that will most concern them is what is referred to as the “special verdict in respect of insanity”.

Opening the trial today, Mr Costelloe told the jury that the prosecution alleges that in the early hours of the morning Mr Costa “struck his wife with knives and then severed her head from her body with one of those knives. He decapitated her.” 

He said Mr Silva called emergency services giving his address and saying he thought he had injured his wife.

Armed gardaí went to the apartment and were met by Mr Silva wearing only shorts and flip-flops. 

When they entered, gardaí will say that they found Ms De Campos Silva lying prone in a doorway between the bedroom and hall, partially clothed and with a knife protruding from her breast. 

“Her head was clearly separated from her torso,” counsel added.

Following the opening, defence barrister Garnet Orange SC made 15 admissions on behalf of his client, including that Ms De Campos Silva died as a result of injuries caused to her by the accused at their home.

Mr Orange said that in due course he will be asking the jury to return a special verdict under the Criminal Law Insanity Act 2006.

Niall Murray of Dublin Fire Brigade was the first witness called.

He told Mr Costelloe that he received the 999 call from Mr Costa Silva at about 6.15am on 4 November, 2021.

He said Mr Costa Silva had a “very calm demeanour” and told him that “he thinks he killed his wife” and later said that he had killed her. 

The emergency call was played for the jury and Mr Murray agreed with Mr Orange that at the start of the call, Mr Costa Silva could be heard saying: “I have fought with my wife, she tried to kill me.”

The trial continues before Mr Justice Michael MacGrath and the jury.
