A convicted murderer has been handed another jail sentence for deliberately causing a head-on crash with his ex-partner’s vehicle while he was on parole.

Timothy Francis Allen, 53, faced Brisbane District Court for sentencing on Thursday, having earlier pleaded guilty to stalking with violence and acts intended to cause grievous bodily harm.

Allen was jailed for life in 1993 for joining with another man to rob, bash, stab and cut the throat of taxi driver Robin John Miller after getting in his vehicle in Fortitude Valley on August 11, 1990.

The court heard Allen’s partner ended the relationship in October 2021. In the three days prior to his vehicular assault, Allen sent the woman hundreds of text messages, followed her home and repeatedly knocked on her door.

Crown prosecutor Toby Corsbie said just after midnight on October 13, Allen sent the woman a picture of the registration plate of a vehicle belonging to a male friend who had visited her along with pictures of her house.

The woman got in her car to leave her home in Brisbane’s southwestern suburbs at 5am that morning, with her male friend accompanying her in a separate vehicle, when they saw Allen’s vehicle approaching.

“(Allen) positioned himself facing (the victim’s) path of travel. He accelerated heavily, crossed the white lines and drove head first at speed into (the victim’s) car and only braked momentarily at the end,” Mr Corsbie said.

“He got out of his car .. .he accused her of sleeping with (her male friend).”

The victim suffered neck sprain, abrasions and bruising from the crash, but Mr Corsbie said Allen had acted with intent to cause much more serious injuries.

“One of the most worrying aspects of this is the planning that went into this, checking with her work to see if she would be there that day, anticipating her route and then lying in wait,” Mr Corsbie said.

Allen’s barrister, Kim Bryson, said her client had “some insight, albeit limited” into his offending.

“He was controlling and jealous during his time in the relationship. He is willing to undergo therapeutic treatment,” Ms Bryson said.

Ms Bryson said Allen had struggled to complete courses while in jail due being deaf and unable to access an AUSLAN interpreter and having autism spectrum disorder.

Judge Michael Burnett said Allen had engaged in “manipulative behaviour” toward his ex-partner and his plan to cause a collision with her car was “inherently dangerous”.

“She was scared of you and one assumes she had her friend drive their car behind her out of fear,” Judge Burnett said.

“You crashed head-on at significant speed and pushed her car backwards into a parked utility.”

Judge Burnett said Allen only stopped his confrontation with the injured woman after her male friend intervened and pushed him away.

Allen was sentenced to six years in jail with an eligibility date for parole in October this year, due to him spending the previous 18 months in custody.
