Austin Taylor Bice was last seen Friday after a night of partying with friends according to Spanish newspapers. They're reporting that he left his ID behind and has not used his credit cards since his disappearance.
Bice, originally from Carlsbad, played football at Torrey Pines High School. He is currently studying abroad in Spain through an SDSU exchange program.
Roommates and friends have posted flyers in Madrid hoping to gain some information about his whereabouts.
One roommate told the newspaper El Pais that Bice was last seen at a nightclub, standing outside after being refused entry by bouncers. The roommate claims Bice was too intoxicated to be admitted to the club, the paper reported. It was while he was waiting outside the club with a friend that Bice decided to leave on his own, his friends said.
Police have opened an investigation into Bice's whereabouts according to the paper.
Bice's father arrived in Spain Wednesday to help in the search while friends and family are asking for help on Facebook.
Bice's father told El Pais that he hasn't been eating or sleeping and is under a lot of pressure to find his son, according to the paper's translation.
His mother spoke with NBCSanDiego Wednesday night but was obviously upset about her son’s disappearance but wasn’t ready to speak publicly.
The university issued a statement Wednesday:
"We were made aware of the situation on February 27th and we're deeply concerned. We've been in regular contact with the host university, as well as the local authorities in Madrid, the State Department and his family and we are doing what we can to help in the search for him."
