SYDNEY (AP) — An Australian woman who lost her brother in the disappearance of Malaysia Airlines Flight 370 has now learned that her stepdaughter was on the Malaysia Airlines flight shot down over Ukraine.

Kaylene Mann’s brother Rod Burrows and sister-in-law Mary Burrows were on Flight 370 when it vanished in March. On Friday, she found out that her stepdaughter, Maree Rizk, was killed along with 297 other passengers on board Flight 17 when it crashed in Ukraine.

Mann’s brother Greg Burrows said news of the second tragedy to hit the family has “ripped our guts again.”
