Wigginton was the only one of the four co-accused who pleaded guilty to the charge of murder. Therefore, there was no trial and few details were disclosed to the court as to why this incident occurred. Her then-girlfriend, Lisa Ptaschinski, and two other women fueled rumors about Wigginton having vampiric tendencies, stating that the reason for the murder was to enable the drinking of the man's blood.
On the night of the murder, Wigginton, Ptaschinski and two other women lured 47-year-old Edward Baldock to a park on the banks of the Brisbane River. There, Wigginton stabbed him 27 times, nearly severing his head.
She made four unsuccessful parole applications until 2011 when the parole board granted her application.
The case still commands strong media interest and public reaction. In April 2008 it has been reported that Lisa Ptaschinski, one of the other killers, will be released from prison after nearly 22 years. Under the resettlement leave program, Ptaschinski will be given a maximum of 12 hours leave every two months for six months.
However, it was later reported that the earlier reports of possible release were false.
Wigginton was released from prison on January 11, 2012 after a successful parole bid. This was Wigginton's second parole application.
