Spanish police are investigating the accidental drowning of University of Alabama student James Gracey after his body was recovered from the Mediterranean Sea.Surveillance footage captured Gracey walking alone toward a rocky breakwater near a Barcelona nightclub before he fell into the water around three in the morning.Although a man was arrested for possessing the student's cellphone, investigators believe the device was found on the street and rule out any third-party involvement.Authorities are currently awaiting toxicology results to determine if the twenty-year-old was under the influence of drugs or alcohol at the time of the fatal fall.
