Flags flew at half-staff around Ireland and the country's parliament suspended normal business Wednesday as the nation mourned six students killed when a balcony collapsed during a party in Berkeley, California.

Prime Minister Enda Kenny offered a message of sympathy and books of condolences were opened at University College Dublin, where three of the students studied. Tributes were paid to the students, who were among 700 Irish students in the San Francisco Bay Area for the summer.

OLIVIA BURKE

Burke, 21, was expected back at the Dun Laoghaire Institute of Art, Design and Technology, in September to start her final year of a degree in entrepreneurship and management.

Annie Doona, the institute's president, said Burke was working at a sushi restaurant and sharing an apartment with some of the others killed and injured in the Berkeley balcony collapse.

"She was doing very well, and enjoying herself and making great friends," Doona said. "It's terribly sad."

The school was providing psychological support for students on the campus, she said.

"Although the students have finished, we think that some of them will come here. They'll want to meet, they'll want to hug, they'll want to talk about Olivia, and they'll want to spend a bit of time just thinking about her and grieving," Doona said.

EOGHAN CULLIGAN

Culligan had finished his third year at the Dublin Institute of Technology, where he was studying logistics and supply chain management.

Ballyboden St. Enda's — the club where he played Gaelic football — posted a tribute to him.

"Eoghan was very popular with his teammates and this tragic news is keenly felt by all members of our Club, but especially by those players and mentors who knew him well," the club said. "We would like to extend our deepest sympathy to his parents Gerry & Marie and to his brothers Stephen & Andrew and to all the extended Culligan family."

LORCAN MILLER

Miller was studying medicine at University College Dublin. At his high school, St. Andrew's College in Booterstown, south Dublin, headmaster Peter Fraser recalled Miller as a "positive, engaging, decent boy who was incredibly talented, but normal, modest and balanced about it all."

Miller played on the school hockey team, sang in the choir, performed in musicals and took part in the school's Model United Nations.

"He was hugely popular," Fraser said.

NICCOLAI SCHUSTER

Schuster, 21, was studying at University College Dublin and had been a student at St. Mary's College in the Rathmines district near the Irish capital. In 2010, he took part in the Ghana Immersion Project, which sends young people to the West African country, where they attend school with local students and help primary school students learn English.

EIMEAR WALSH

Walsh, a medical student at UCD, was a high school classmate of Burke's at Loreto College in Foxrock, south Dublin.

The principal at Loreto described the two girls as smart and beautiful.

"They were in the prime of their lives," said principal Bernadette Prendiville. "They had a successful time in school, went about their work quietly and had everything going for them, everything ahead of them."

The Church of Our Lady of Perpetual Succour in Foxrock held a vigil Tuesday in the aftermath of the tragedy. Parish priest Frank Herron, who knows the Walsh family, told Irish broadcaster RTE that the community was shocked and the family distraught.

"The tragedy is that they were heading out full of life and full of the joys of summer," he said. "It's the last thing anybody would be expecting, that something like this would happen."
