Taperoo death: Adelaide Caroll Hopkinson accused of murdering her husband Simon 'Hoppo' Hopkinson as new details emerge

A mental health nurse has faced court for the first time over the alleged murder of her husband, as horrifying new details about the crime scene emerged.

Caroll Hopkinson, 58, was charged over the death of Simon 'Hoppo' Hopkinson, 60, after his body was discovered at the couple’s Taperoo home in Adelaide's north-west on Sunday morning.

Hopkinson, a mental health nurse with over 20 years experience was allegedly the one who called police to the home on Sunday.

Shocked neighbours claimed they saw Hopkinson sitting at the front of the house appearing 'nonchalant', before she was arrested and escorted from the scene by police. 

Hopkinson appeared in Port Adelaide Magistrates Court on Monday still dressed in the pyjamas and pink dressing gown she was arrested in with bandages wrapped around her hands.

She remained silent in the dock as her defence lawyer told the court there would be no application for bail.

Police prosecutors told the court they require at least 20 weeks to examine evidence, including analysis of the alleged crime scene, the Adelaide Advertiser reported.

'We require around four months and four weeks, just to get some blood splatter analysis,' the prosecutor said.

The cause of Mr Hopkinson's death has not been revealed. 

Hopkinson was remanded in custody and reappear in court again in November, unless a bail application hearing is called before then.

It's understood that the couple were both psychiatric nurses.

Hopkinson's LinkedIn profile reveals as well as being a registered nurse working in mental health, she operated a small pet boarding facility called Cat Catraz, 'The ultimate in small pet boarding.'

Hopkinson's lawyer declined to comment on the cause outside court.

The couple's home remained a crime scene on Monday. 

Shocked neighbours were horrified to hear about the alleged incident on what is usually a quiet suburban street.

One woman said although though she didn't know the pair very well, they 'seem lovely'.

Other neighbours described them as 'a happy couple' and 'beautiful people'.

Kyla Vermeulen, a resident of the street for 14 years was 'pretty shocked' to hear of the death, adding that 'it's quite sad'.

She added it was 'mostly older people and families' who lived in the area.

Another local resident Matt Carr told the ABC that he heard sirens when he woke up and 'there was a bit of activity going on out the front'.

'You don't expect to wake up to that in your front yard on a Sunday morning,' he said. 

Police urge anyone with information to contact Crime Stoppers.
