22-year-old college senior missing after "polar plunge" in California

Hamzah Alsaudi, a San Francisco State student, disappeared Thursday during a "polar plunge" at Esplanade Beach in Pacifica, California, police said in a news release. 

At around 10:30 a.m. on Jan. 19, police were called to the beach for a swimmer in distress. Officials said that Alsaudi and two others went into the ocean, but while in the water Alsaudi, 22, was hit with a large wave that pulled him further from shore. 

The other two swimmers were able to make it back to the shore and called 911 for help, police said.
