HE was hidden from view for 20 years.
After killing 35 people in Tasmania's Port Arthur on April 28, 1996, Martin Bryant disappeared into jail and his images vanished from the public's view.
Seven's Sunday Night has unearthed bizarre and tragic video recordings taken by police in the aftermath of a murderous rampage that would change Australia forever.
They show Bryant laughing when he is told about the deaths and injuries caused in the mass shooting.
Bryant's lawyer John Avery described the killer's "girlish giggle" and said he was a 28-year-old man with the IQ of a small child, and was desperate for attention.
Avery told Seven how Bryant was not intending to confess to the charges so he could enjoy the spectacle of a court case where he could see the faces of stricken families.
"When he was wheeled in in a wheelchair with his legs manacled and handcuffed and with a big grin on his face like a school boy, it didn't frighten me," Avery said.
"I could see without the gun, without the weapon, he was nothing. He was a sad, insipid little boy."
Avery also learned that Bryant began his rampage to punish David and Sally Martin, a couple who lived on a nearby farm they refused to sell to Bryant.
"He had a long grudge against them so he told me…'I tried to buy the farm off them before, and offered them a lot of money but Mrs Martin would say to me 'I'm never going to sell it. It doesn't matter how much money you offer me Martin.' So I shot them in the head'."
Avery has since been disbarred as a lawyer after being jailed for embezzling client funds.
He said he felt Bryant wanted to die famous, but likely never expected it to take so long.
