Teen accused of killing Good Samaritan refused bail

A teen accused of intentionally mowing down and killing a Good Samaritan on the Gold Coast has been refused bail.

Alexander Kirke was charged with murder in January 2017 over allegations he deliberately ran over Darren Pullar while leaving the scene of a home invasion at Broadbeach Waters on Boxing Day a few weeks earlier.

He applied to the Brisbane Supreme Court today to be released on bail.

The court heard there were varying accounts about what allegedly occurred in the early hours of December 26, 2016, with some claiming Mr Pullar fell in front of the car while another said he was standing with his hands on the bonnet.

Defence lawyer Christopher Schrader said with the evidence, it would be difficult for the prosecution to prove Mr Kirke intended to murder the Yatala man.

"He can show cause as to why his continued detention in custody is no longer justified," he said.

Prosecutor Carly Whelan said although there were "conflicting" witness statements, there was enough evidence to support a murder charge.

"The witnesses all speak about the vehicle accelerating in some way and hitting the victim, and that they continue to drive and that he was driven over," she said.

"The witnesses speak about him having been dragged some metres."

Police say Mr Pullar came to the aid of neighbours when two men allegedly broke into the property next door about 1.25am.

The 50-year-old reportedly chased the pair outside when he was run over by the getaway vehicle, which was allegedly being driven by Mr Kirke.

Ms Whelan said the teen should not be released on bail because he was a flight risk, had a capacity "to endanger members of the public" and interfere with witnesses.

She also expressed concerns for his own safety.

The court heard Mr Kirke had been recorded saying he wanted to leave Queensland and live in New South Wales.

Justice Glenn Martin said that in itself was enough to raise concerns about his suitability to be released on bail, let alone the other factors.

Justice Martin noted the matter was yet to be committed to trial, but refused Mr Kirke's bail application.
