The couple had moved to Miami Beach after retiring from the International Monetary Fund in Washington D.C. and from a company called IntelSat.
Claudio Bonnefoy was the uncle to former Chilean president Michelle Bachelet. Bettina has always been close to her aunt Maria and had arrived from D.C. to visit when the building collapsed.
"She was more than a matriarch, for me more than an aunt, she's my second mom," Obias said.
Obias and her extended family, who traveled from around the country, will hold a special memorial service for the beloved couple on Saturday.
Then Obias will be returning home to D.C. and says this experience has changed her.
