Vulnerable women the target
From his first offence at age 15, when he used a replica gun to force a teenager into an abandoned building, TJD's crimes reveal a disturbing pattern.
Between 1991 and 2003 he targeted Perth women when they were alone and vulnerable as they walked home or slept. One woman he attacked while she was visiting a cemetery.
A 2011 judgment, which ordered TJD remain behind bars as a dangerous sex offender, detailed offences against 13 women. The first was on August 21, 1991, about the time TJD was drinking heavily and using cannabis and methylamphetamines.
The 19-year-old victim escaped from the empty building but TJD accosted a 23-year-old woman on the same footpath the next day. He threatened to "blow her away" but she realised his gun was fake and escaped.
Next TJD pointed the fake gun at a 17-year-old and told her "if you do what I say you won't get hurt". She was forced into a men's toilet and raped by TJD, who invited in a friend to rape her with a threat to "blow her brains out" if she did not submit.
Two months later, TJD was staying with a cousin and a 23-year-old woman when he put on a stocking mask and went into the woman's bedroom with a knife.
He threatened to cut her and her daughters' throats if she did not have sex with him, but the woman fought him off and fled.
TJD pleaded guilty to these offences and another two in Perth Children's Court in March 1992.
He was given three years detention and released after two, but struck again just six weeks later.
Between April and June that year TJD carried out four indecent assaults and attempted another and was jailed for 16 months after a guilty plea in Perth Children's Court in 1995.
Five years later, TJD grabbed an 18-year-old walking home, pressed a knife into her back and forced her into a dark, deserted area where he sexually attacked her and stole money. He was caught via DNA testing.
In 2003, TJD followed an 18-year-old to her grandmother's grave at Midland and threatened to kill her. She screamed, they punched each other, then fled in opposite directions.
TJD pleaded not guilty to threatening to kill, deprivation of liberty and assault occasioning bodily harm but was convicted.
In the 2011 order which kept TJD behind bars, Judge Kevin Sleight said he needed individual psychotherapy in prison and until he got it, he was a high risk to the community.
