Nick Alexander, the merchandise manager for the American band Eagles of Death Metal, was one of the 89 victims killed during the band's concert in the shooting at the Bataclan Theater in Paris on Friday, Time magazine reported. Alexander's family and friends paid tribute to him via social media.

The shooting was one of six terrorist attacks that took place throughout the city led by Islamic extremist group ISIS, CNN reported. Other locations of the attacks included the Stade de France sports stadium and at least two restaurants.

Alexander was a 36-year-old British man who worked as a merch manager for Eagles of Death Metal and other popular rock bands including Alice in Chains, Sum 41, Panic! at the Disco and the Black Keys, according to Rolling Stone. He is survived by his family and girlfriend Polina Buckley.

"It is with huge sorrow that we can confirm that our beloved Nick lost his life at the Bataclan last night. Nick was not just our brother, son and uncle; he was everyone's best friend - generous, funny and fiercely loyal," Alexander's family said in a statement obtained by Rolling Stone. "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. Thank you for your thoughts and respect for our family at this difficult time. Peace and light."

Buckley shared a heartbreaking message via Twitter to her late boyfriend, along with a photo of the couple sharing a kiss.

"You are and always will be the love of my life, Nick Alexander #fuckterrorism #ParisAttacks #Bataclan," Buckley tweeted.

Fall Out Boy guitarist Joe Trohman, Black Keys members Patrick Carney and Dan Auerbach and Alice in Chains all released statements in memory of Alexander.

A GoFundMe page in Alexander's name was created on Friday to help his family pay for memorial services.
