One person was killed and seven others were wounded when a gunman opened fire at the Burnette Chapel Church of Christ in Antioch, Tenn., on Sunday morning, according to police. The suspect was among the injured.

By the afternoon, the Metropolitan Nashville Police Department had identified the woman churchgoer who was fatally shot as Melanie Smith, 39, from the Rutherford County town of Smyrna, Tenn.

Police say the alleged shooter is 25-year-old Emanuel Kidega Samson. "He has been released from hospital and will be charged with murder and [attempted] murder," the MNPD tweeted. Authorities have not commented on a possible motive for the shooting.

Police say they started receiving calls about the shooting around 11:15 a.m. ET. Nashville police Public Affairs Manager Don Aaron says six of the injured, three men — including the suspect — and three women, were being treated at Vanderbilt University Medical Center. Two other victims were taken to Skyline Medical Center.

The Nashville Fire Department tweeted that all but one of the victims is over 60 years old.

Nashville Mayor Megan Barry released a statement expressing her condolences to the victims and their families.

The Burnette Chapel Church of Christ, which has a weekly service at 10 a.m., is located about 10 miles southeast of downtown Nashville.
