A QUEENSLAND family who lost a son and daughter-in-law on flight MH370 have lost further family members on board MH17 shot down over Ukraine.

Irene and George Burrows, from Biloela in central Queensland, have been mourning the loss of son Rodney and daughter-in-law Mary aboard Malaysia Airlines flight MH370, whose final resting place still remains unclear.

On Friday, they were devastated to learn step-granddaugther Maree Rizk and her husband Albert from Sunbury near Melbourne were killed in the MH17 explosion.

Irene’s son Greg Burrows said while it was not his role to make a formal statement on behalf of the family, he said the latest loss had shocked the family deeply.

“It has been a very trying day,’’ he told The Courier Mail.

“This has just blown everyone clean out of the water.’’

The Burrows family have spoken in the past of their heartbreak at the failed search for MH370.

Rodney and Mary Burrows were travelling on MH370 with close friends Cathy and Bob Lawton on their way to a holiday in China.

Their son Jayden Burrows, in a statement in March, said the family was trying to come to terms with the “terrible tragedy” aboard MH370.

“We dearly love and will miss our Mum and Dad,’’ he said.

“The love and compassion that they shared and their priority of putting their family first will help us get through this together.

“We are heartbroken this stage of their life has been cut short.”
