The Copeland family hails from Lakeway, Tx., about 32 kilometres northwest of Austin. They had been on vacation to celebrate Kim’s 40^th birthday. The surviving family members also include Maegan Copeland, 29, and Austin Copeland, 22, Sean’s children from a previous marriage.

Copeland said the family has been overwhelmed by messages of love and tributes to Sean and Brodie.

But despite the tragedy, she said she doesn’t regret going abroad for the vacation.

“We had the most amazing days and minutes together as a family of five that I wouldn’t take back,” Copeland said. “I get up and go for them. So that they know I’m OK, because neither one of them would want me to be sad.”
