The father of an Australian man shot by intruders at his U.S. family home has landed in Texas to see his son's body.
Brenton Estorffe, 29, was gunned down in the lounge room of his home in Fort Bend County, Texas, just after midnight on Wednesday.
His father Michael Estorffe arrived at Houston Airport on Sunday morning saying 'it still hasn't sunk in that it is real'.

Mr Estorffe said he planned to start funeral arrangements and visit his son's home to see the scene of the crime for himself.
'We lived here in Houston for two years, it was a great place. We really enjoyed it here. This is a real tragedy to us,' he told reporters.
He was greeted at the airport by the sister of Angeleanna Estorffe, his son's wife, and Australian Consul General to Houston Peter McGauran.
'[Brenton's children Asher, 3, and one-year-old Eliana] will miss their father but hopefully we can help them get on with everything,' he said.
'We will just rest at home today and… have some reflective time with Ange and the grandchildren.'

His wife Denise and daughter Paige arrived a day earlier as Mr Estorffe had problems obtaining a U.S. visa because he had worked for an oil company in Kurdistan.
He thanked his friends and government officials who helped get the visa organised so he could make it to his son's adopted home.
Mr Estorffe earlier said he hasn't been able to sleep since the harrowing call from his daughter-in-law that told him 'Brenton's been shot'.
Police are desperately trying to track down the two intruders who are accused of slaying Brenton releasing surveillance footage on Saturday of a 'vehicle of interest' and their descriptions.
'All Ange said was, 'Brenton's been shot, I'll call you later', and the phone went dead,' Mr Estorffe told The Australian.

'My wife Denise was left hanging on the phone, and that's when the mass hysteria set in.'
The parents of the 29-year-old were left waiting an agonising two hours before a series of frantic phone calls confirmed their son had died just three minutes into his birthday.
'He wrestled those two blokes away from his wife and kids. That's when they shot him. Unfortunately he paid the highest price,' Mr Estorffe said.
The father from Queensland was killed after waking up to investigate the sound of a glass door smash in the middle of the night.
His father Michael had been struggling to secure a visa to attend his son's funeral, due to be held on Tuesday.
He had been stranded in the family home in Mooloolaba on Queensland's Sunshine Coast while his wife and three children flew to be by the side of Brenton's family.
