The third person was being treated at a hospital, she said.

All three of the victims were initially described as being in critical condition after shots rang out inside the church just before 10 a.m. One of the victims is believed to be the shooter, said Mike Drivdahl, a public information officer with the Fort Worth Fire Department.
