A $100,000 reward was being offered for the safe return of a UC Berkeley student who went missing after leaving a party near the University of Southern California campus early Saturday morning, family members said.

Eloi Vasquez, a 19-year-old freshman who plays on the school’s soccer team, walked out of a fraternity house in the 600 block of West 28th Street about 1:30 a.m. with only his cellphone in hand.

His friends tried to get him to come back to the party, but he told them over the phone he “was going to the beach.”

Vasquez then called a friend, Aurora Cardena, in Northern California at 2:18 a.m. and told her he was “screwed” and got lost, his mother Wendy Margolin said.

“He pretty much said, ‘I need you to come over here, I need help.’ I asked him ‘Where are you?’ and he told me that he was in LA and that he didn’t know where he was at and that he was lost,” Aurora Cardenas told NBC Bay Area. “The second time he called it just clicked. I didn’t know if his phone died, or if he hung up.”

When Vasquez left the party he didn’t have his wallet, money or ID with him. The phone he used to call his friend has since died.

“Everyone knows how responsible he is, how dedicated to school he is and he hasn’t contacted anyone since,” Margolin said. “Something is going on with him.”

Vasquez’s parents drove to LA from Northern California on Saturday hoping to find their son. The home where Vasquez was last seen has since been littered with fliers by friends also in hopes of his return.
