Relatives of a Queensland woman who admitted murdering her grandfather say they’ll forever question whether they missed warning signs that could have prevented the horrific killing.
Brittney Dwyer, 20, last year drove to Adelaide with the intention of robbing pensioner Robert Whitwell of $114,000 in cash he kept at his home.
However, Dwyer ended up stabbing the 81-year-old to death and both she and friend Bernadette Burns, 22, have pleaded guilty to his murder.
Dwyer’s mother, Tonya, describes her daughter as strong-willed, adventurous and a “tomboy” growing up, but now questions whether she should have picked up on changes.
“What are the signs that I missed?” she told Channel Seven’s Sunday Night program.
“What didn’t I see?”
Brittney’s brother, Ryan Whitwell-Dwyer, also struggles to understand his sister’s motivation.
“I think about what I could’ve done to stop it,” he said.
Prosecutors have described the killing as “almost sociopathic in style” and court documents reveal Dwyer inexplicably washed the dishes as her grandfather died.
Previous hearings have also revealed she was motivated, to an extent, by the gruesome US series American Horror Story.
Dwyer formed a bond with high-school friend Shelby Lee Holmes after isolating herself as a teenager.
Mrs Dwyer says her daughter and Holmes were “a little bit dark” and would visit cemeteries and constantly text one another.
