On South Padre Island, authorities continue the search for a teenaged boy who went missing while swimming in the ocean.

Mario Alberto Silva was swimming past the second sand bar on Beach Access 5. Eyewitnesses say the last they saw of him were his arms either trying to swim back or perhaps call for help.

He is 17 years old and is a resident of Mission, Texas.

At this moment, the S.S. Coast Guard, South Padre Lifeguards and South Padre Island Officials are about to call off the search. Mario’s parents continue the search on their own.
