The Duncanville Police Department identified the shooter as Brandon Keith Ned, 42, of Dallas. Further information about the suspect will not be released due to the ongoing investigation, a DPD press release said.

Police arrived at Duncanville Fieldhouse, a large indoor facility, about two minutes after receiving an emergency call, according to an earlier police news release.

“Officers quickly located and exchanged fire with a suspect armed with a handgun. The suspect was injured in the exchange,” the department said. The man was taken to a nearby hospital where he was pronounced dead, police said, and no children, staff or officers were injured in the incident. The identity of the shooter has not been released by police.

The gunman had entered “through the main hall doors with a handgun”, and at least one bullet was then fired, Duncanville Deputy Police Chief Matthew Stogner said Monday at a conference Press.

“It appears he and a member of staff had an exchange – whether it was talking, talking, but it was the initial gunshot” that alerted others in the building, Stogner said. . Counselors immediately began moving the children to a safe area and locking the doors, he said.

“The suspect went to a classroom, was unable to get inside, and fired a bullet into the classroom where there were children inside,” Stogner said.

The suspect then moved to the gymnasium where other children were, police said, but no shots were fired. Officers arrived at the scene and saw the suspect in the gymnasium, and gunfire was exchanged after confronting him, police said.

“Camp and Fieldhouse staff followed lockdown procedures. Due to the clear-headed actions of staff and the quick response time of law enforcement, there were no additional injuries,” said the police. “The Duncanville police officers have completed their training and the City commends them for their actions today.”

The summer camp is for children ages 4 to 14 and was entering its second week with an average attendance of more than 250 campers and staff, police said.

The Texas Department of Public Safety has been asked to take over the investigation, Duncanville police said. The motive for the shooting has not yet been established.

Duncanville is located approximately 10 miles south of downtown Dallas.
