Jean Eric Gassy was a psychiatrist deregistered in 1997 after Dr Margaret Tobin, his former boss, flagged his fitness to practise. Convinced she had conspired to destroy his career, he drew up a hit list of doctors and, five months before her death, followed her to a conference in Brisbane armed with a gun, only to drop it on the pavement outside and abandon the attempt.
On 14 October 2002 he tried again, flying to Adelaide, disguising himself and following Tobin into the lift of her Hindmarsh Square office. As she stepped out onto her floor, he shot her four times, then removed his disguise and walked away. Convicted of murder in 2004, he won a retrial when the High Court found the trial judge’s directions had caused a substantial miscarriage of justice; a second jury convicted him again in 2009, and he remains in prison with a non-parole period of 34 years.
