The first names of victims of the horrendous terrorist attacks that unfolded Friday night in six locations throughout Paris began to emerge Saturday, painting the first strokes of a portrait of the many lives that were lost in multiple gruesome events.

The merchandise manager of a band whose concert was the scene of a mass shooting carried out by terrorists that night was among those killed by assailants, his family has confirmed. Nick Alexander, the 36-year-old manager, and more than 80 other attendees at the show were shot by attackers clad in black who entered the Bataclan concert hall when the band was about an hour into its set and began firing directly in the crowd.

Fans who were in attendance described a ghastly scene, with victims gunned down one-by-one as others in the crowd hunkered close to the floor and listened to 10 minutes of steady shooting. They said the only pause came when the assailants reloaded their guns. Some fans escaped out of an emergency exit, while others sought refuge in an attic.

Amid the chaotic and uncertain hours that followed, Alexander's partner, Polina Buckley, tweeted a photo of him asking for help in locating his whereabouts.

Officials have said at least 129 people died in a set of coordinated shootings and explosions that took place across the city on Friday, at the concert as well as in cafes and outside of a soccer stadium. Another 352 people were injured in the attacks. The terrorist group Islamic State has claimed responsibility for the assaults.

Alexander was on tour with Eagles of Death Metal, an American blues-rock band based in Palm Desert, California, to promote a new album called “Zipper Down.” The band has canceled the remainder of its tour and plans to return to the U.S.

"Nick was not just our brother, son and uncle, he was everyone's best friend -- generous, funny and fiercely loyal. Nick died doing the job he loved and we take great comfort in knowing how much he was cherished by his friends around the world,” Alexander’s family said in a statement.
