Fuller says Tarrant has spent little time in Australia in the past four years and Acting Deputy Police Commissioner Mick Willing says Tarrant was only known to police for "minor traffic matters'". No images have emerged from there. He said he survived by played dead, but was desperate to know what happened to his friends who were there with him.

Shah Mahmood Qureshi says authorities in Christchurch, where the shootings took place, are trying to determine whether three other Pakistanis who have been missing since Friday's attack were among the fatalities.
He said they were praying "to our God of all peoples and of all cultures for peace, tolerance and good will". Now i think she is one of a kind.
He has been remanded in custody until April 5 and police have said more charges are likely to follow.
New Zealand law enforcement is working with Australian intelligence and police in the "wide-reaching" investigation, the commissioner said.
Two more people, whose identity remains unknown as yet, were also arrested.
Families of victims described a long first night of waiting for information at Christchurch Hospital and Hagley College, where a community center has been set up.
The hospital also confirmed 39 people are still receiving treatment, with 11 of them in intensive care. But updates were slow to come, and many families were still waiting to hear whether their loved ones were among the victims.
Ardern noted that this individual traveled around the world and spent "sporadic periods of time" in New Zealand.
At least one Palestinian died, Palestine's ambassador to Australia and New Zealand said in a statement.
The majority of victims were migrants or refugees from countries such as Pakistan, India, Malaysia, Indonesia, Turkey, Somalia and Afghanistan.
