@abcnews: Authorities are investigating whether a teen who went missing in Nashville was overserved at a local bar owned by country singer Luke Bryan. Riley Strain was last seen by friends at 9:52 p.m. last Friday after drinking downtown in the city's Broadway area, Nashville police said. TC Restaurant Group, operator and owner of Bryan's bar, said earlier this week that it's working with police "to provide security camera footage and any other potentially helpful information to aid in the search for Riley Strain. Our thoughts are with his family and loved ones for his safe return." #nashville #news #abcnews
