A recent Senate-approved bill, "Lulu's Law," aims to establish a national wireless emergency alert system for shark attacks, inspired by 16-year-old survivor Lulu Gribbin.

The Senate-passed Lulu's Law would allow authorities to send out cell phone alerts when there's been a shark attack.

The U.S. Senate unanimously passed Lulu’s Law, a bill that enhances the national shark alert warning system. The legislation is inspired by Lulu Gribbin, one of two Mountain Brook teenagers injured in a shark attack at Fort Walton Beach last year.
