A second woman has been charged with the attempted murder of a man at a health centre in Adelaide, a day after the victim's ex-partner was extradited from a Pacific Island.
A 34-year-old woman was arrested at her home in Everard Park in Adelaide's southwest on Friday.
She was charged with attempting to murder Jonathan Hawtin at the Hampstead Rehabilitation Centre.
The woman was remanded in custody and will face court on Monday.
It came a day after Mr Hawtin's ex-partner, former academic Lisa Lines, 43, was extradited from a Pacific Island.
The historian - a respected expert on the Spanish Civil War - was taken into custody in the island nation of Palau earlier this month and arrested on her arrival in Brisbane on Thursday.
The arrest relates to a convoluted series of events that began with a violent incident in the Adelaide Hills in October 2017.
Mr Hawtin was rendered tetraplegic - paralysed from the neck down - after allegedly being struck repeatedly in the neck with a hatchet by Lines' then-partner Zacharia Bruckner, who was shot in the abdomen.
Mr Hawtin, 36, was charged with attempted murder for shooting Bruckner, 30, with police assuming the younger man was acting in self-defence.
However, a jury of six men and six women unanimously acquitted Mr Hawtin in 2019 after three hours of deliberation.
Lines had in June 2017 told Mr Hawtin, with whom she had two children, that she wanted to separate, the jury was told.
She began a romantic relationship with Bruckner in August that year.
In 2020, major crime detectives in South Australia reopened the investigation, resulting in a warrant being issued for Lines' arrest.
Bruckner was arrested in Brisbane earlier in November on conspiracy to murder offences and extradited to SA.
The pair are accused of attempting to murder Mr Hawtin in the October 2017 incident, as well as co-conspiring to murder Mr Hawtin and his mother Rhonda Hawtin between December 2021 and August last year.
Lines is also charged with attempting to murder Mr Hawtin on New Year's Day 2018.
