Murder leaves family in disbelief

It has been two years since Christine Johnson last saw her son but she still expects him to knock on her door, flash a cheeky grin and say, "Hello trouble".

It was David Liam Johnson's standard greeting when he visited his mum and she never would have guessed she would miss it so much when he was gone.

"I'm still trying to accept the fact that he is never going to come back," she said.

"You expect him to knock on the door. You walk down the street and you think, 'There's Dave', but then you realise it's not him and he isn't here any more."

Mr Johnson, 32, was murdered by strangers in March 2013 after a minor dispute at a gathering in Swanbourne spiralled out of control.

He was repeatedly assaulted in a street before being shot in a nearby park surrounded by multimillion- dollar homes in a final act of violence.

After a month-long trial last year, Alexander James Stephens and Angus William John Ritchie were found guilty of his murder.

They will be sentenced in the Supreme Court today with Nathan Michael Beckton, who pleaded guilty to manslaughter a few days into the trial.

The three met Mr Johnson just hours before he was killed and had no idea he was a surf-obsessed wanderer who loved animals and meant the world to his family.

Described by sister Bree Lodge as a gypsy, Mr Johnson moved constantly but could not stand to be away from his family for too long.

Mrs Lodge, who gave birth to her second child Kaelani the day before her brother was killed, said the whole situation still felt surreal.

"I miss his cuddles, the big bear hugs and his smile," she said.

After Mr Johnson's wake, his family and friends jumped off the Old Mandurah Bridge in their suits and black dresses.

His mother watched as he jumped off the same bridge a week earlier while they were catching up over a beer on a hot day.

His sister Ele Johnson said it was typical of her adventure-loving sibling.

"I spoke to him on the phone a few weeks before and he was happy, he was running amok and he was exploring all over," she said.

"We used to have so much fun with him. It didn't matter what you were doing, he made it fun."

Mrs Johnson sat through the 4½-week trial and will be in court again today with her family.

She said the experience had been confronting but she had a lot of support from prosecutors, police and the organisation angelhands.

"David can't speak for himself, so it's up to us to be in court united as a family," Mrs Johnson said.
