Florida Hoxha, a graduate of the City University of New York School of Law and Emory University, was also in Greece with her brother, Florin Hoxha - who was killed in the accident alongside his wife, Eris Cani, who was five-and-a-half months pregnant.

Florida Hoxha had worked for the New York Legal Assistance Group for five years, but she held political aspirations, according to Westchester County legislator Vedat Gashi.

 She cared deeply about her environment,  he told ABC7.  We have similar backgrounds. We're both Albanian Americans. And she had a deep passion for helping other people. 

Gashi described his friend as someone who was  smart, ambitious and devoted to her community. 

 I was deeply impressed by her, and I was excited to see where her passion and drive would take her,  he said.  That future was taken far too soon.

Emory University alumnus Florin Hoxha, 36, was also killed. He co-founded the construction company, Prufock Builders, alongside his brother, Clyde.

Meanwhile, his wife, Cani, was an assistant professor of pharmacy practice at Touro College, a private university steeped in Jewish tradition.

Her background has always been in pharmacy since starting as an intern at Rite Aid in Philadelphia at 2007, where she worked for seven years.

She graduated from Temple University School of Science and Technology in 2009 before receiving her doctorate in 2014.

Cani practiced at the Bronx Lebanon Hospital, specializing in infectious diseases, and held residencies at the Einstein Medical Center in Pennsylvania and the SUNY Downstate campus in Brooklyn.

Edmond Hings, 78, and his Greek wife of 11 years Athena Papaprescou, 77, were also killed.

Greek authorities are still investigating the cause of the building collapse - almost a week later.

Investigators believe a gas leak happened in the apartment where Hings and his wife were staying.

But officials are now examining adjacent buildings after they were  deemed dangerous,  Paris Charlaftis, the Athens deputy mayor, told Greek outlet To Vima.

 The question is whether there is a risk that they could collapse, whether they are on the verge of collapse,  he said.
