A 34-year-old man who survived the June 12 mass shooting at Orlando's gay nightclub Pulse died unexpectedly on Saturday.

According to the Tampa Bay Times, Chris Brodman died while attending a friend's birthday party in Tampa.

Attempts by paramedics to revive Brodman were unsuccessful. He was pronounced dead shortly after emergency personnel found his body in the backyard of the Garden Lake Circle home where the party was being held.

The cause of death is unknown. The county's medical examiner is waiting on results from an autopsy to determine how Brodman died.

Brodman's boyfriend, Cord Cedeno, described Brodman as the “love of [his] life” in a Facebook post.

“I still can't believe my baby is gone. I can't sleep. I can't breathe. I don't know how I'm going to go on without him,” he wrote.

Cedeno has started a GoFundMe crowdfunding page to help pay for funeral costs.
