Biohazard vocalist and guitarist Billy Graziadei saved a young woman’s life in California yesterday while rafting with her boyfriend on the River Kern.

The New York-raised, California-based musician shared the story in a post on Facebook.

He writes: “A buddies son looked at me today while swimming across the raging Kern river and said ‘help’. I dove right in and brought him to shore without a second of hesitation.

“When I got back to shore…a young girl floating in the middle of the river looking at me, with eyes locked onto her as I ran to the waters edge yelling to her if she was ok, she quickly screamed no! I dove and swam to her as quickly as I could. The last thing I saw before diving in was her head going underwater… When I reached her, I had her hold onto my shoulders to rest while I tried to navigate the insane current speeding down the Kern river valley…I quickly decided not to risk crossing the current again and decided to bring her safety on the other side of the river so she could rest while I evaluated her and my next move.

“When we arrived to the other shore, I calmed her down and reassured her that she would be ok. She told me she hit her head while coming down the rapids with her boyfriend, both on the same raft. I asked her where her boyfriend was and she pointed to a rock ledge above us. I asked him if he was ok and he calmly replied yes while not breaking his composure. They oddly passive dude sat there and let me save his girlfriend’s life without lifting a finger or showing any real concern. Maybe he was in shock, but most likely I thought to myself he is just from a different generation than I am.

“I made sure he was ok, sent him across the river in his raft with someone else towing him while I gave attention to his GF. I got her a life vest, put her in the raft and brought her safely back to the other side of the river where she was evaluated my a local nurse. I’m #thankful to have been there and focused enough to see these two situations unfold before my eyes.”
