Search for missing Navy sailor Séamus Gray ends in heartbreak.

The search for 21-year-old Navy sailor Séamus Gray, who went missing after leaving a St. Patrick's Day celebration near Chicago, has been called off after authorities "exhausted every effort" to find him. Gray was last seen walking alone towards Lake Michigan after being asked to leave a bar for appearing drunk. His belongings remain in his room at the naval base, where he was an active-duty fireman recruit. His mother has pleaded for information on social media and police have asked anyone with information to come forward.
