The young man was last seen near the Shoko nightclub in the Vila Olímpica district. Gracey, who was visiting friends in the city, failed to return to his Airbnb accommodation located in the city center.
His family, from Elmhurst, Illinois, has launched an appeal on social media. The University of Alabama student is described as being 1.84 meters tall, weighing 79 kilograms, with dark curly hair.
“"If anyone has seen this boy, please call me or send me a message."
On the night he vanished, he was wearing a white t-shirt, dark pants, and a cross necklace. Authorities are currently working to trace his last movements in the Barcelonès area.
