Authorities in Nashville, Tennessee, have asked for the public's help in identifying a man suspected of a shooting during Easter brunch.

       One man was killed and several others were hurt non-critically in Sunday's shooting, authorities said.

       Police released photos of the suspect on X (formerly known as Twitter) Sunday, and asked people to call the authorities if they have any information.

       Detectives are currently working to "determine a motive" for the suspected gunman opening fire at a restaurant on Garfield St.

       "Shooting occurred at 3 p.m. Gunman fled in this Mercedes GLS 450. Know him? 615-862-8600," read a post on the Metropolitan Nashville Police's X page.
