“It was a horrific night for us,” Benson said. “We’ve done a lot together, that’s the first time though that we’ve ever been swept down a river.”

The pair nearly died after Gunther jumped in the Stanislaus River to retrieve a stick, and the swift current started carrying him away.

“In a state of panic, I jumped in the river as well,” Benson said.

Her plan to save her dog nearly cost both their lives.

“I had only been in there a few minutes and my hands were going numb,” Benson said.

“I could feel myself getting colder, it was getting colder because it was getting darker. And I thought hypothermia is going to be what gets us.”

“And I just started crying out at the top of my lungs for help.”

Incredibly, Gerardo Hernandez heard the calls for help. He followed the voice.

“I just saw a head above the water, I saw another figure,” Hernandez said. “I couldn’t really tell what it was. I guess my adrenaline started kicking in.”

Hernandez held out a 7-foot-long branch and the two made it safely to the shore. Pictures after their successful river rescue show their life-saving celebration.

“Honestly, I think it hasn’t really hit me yet,” Hernandez said. “Because everything just happened so fast.”

Faced with a making a split-second decision, in a scary scenario, Gerardo Hernandez emerged a hero.

“In this world we live in today, it’s hard to find true heroes like that,” Benson said. “I told him that, and I was like, ‘Thank you for saving our lives, you’re our hero!”

Benson says she has a few scrapes on her body but otherwise she is OK.

Hernandez is a Stanislaus State University student.
