It has not been ruled out that Barbara Grice fired the gun she brought to Elberta Elementary School on Wednesday, and one armed parent had to be stopped from entering the school once the incident was made known, law enforcement officials said Friday.

First responders and other emergency personnel from throughout Baldwin County met at the Emergency Management Agency office in Robertsdale on Friday to discuss response to the incident. And while many said the communication between their various agencies could be improved, the overall assessment was that the response to the rural community's lone elementary school was done well and by the book.

It was the first time all of the agencies who responded on Wednesday afternoon could meet in one room, according to Baldwin County Sheriff Huey "Hoss" Mack.

The debriefing included a timeline of events shown on large screens with those who participated weighing in on their role and that of others on scene.

Afterward, Mack talked about the ongoing investigation and said forensic specialists had already removed some evidence from the school, which went into lockdown just after 1:30 p.m. Wednesday.

According to Mack, Grice allegedly came to the back service door of the school's cafeteria and asked to speak to her sister, who works there. The cafeteria worker who answered then went to get the sister, he said.

"And at that point and time this lady just came on in," Mack said Friday of Grice, who is a Foley resident. "And immediately after she came in, that's when we believe she produced the handgun."

Mack said there are some aspects of the investigation that can't be disclosed at this time, but that there was "fractured glass" and a bent metal window frame at the scene, which could have been the result of one or more gunshots. He said two or more witnesses said they heard a gunshot and at least that many, who were in close proximity to Grice, said they did not.

"We have not totally ruled out that there were shots fired at that school," Mack said. "It all happened in a matter of seconds."

And there may even have been shots fired from outside the school, he said. Elberta Elementary and Middle School were locked down in the wake of the incident.

On Friday, Grice was ordered held on $1 million bail and will have to undergo a mental evaluation and cannot go within one mile of a school.

Mack said there have been no reports of anyone else being armed at the school, although there was an incident shortly after Grice's entry where an armed parent had to be detained at the perimeter set up by law enforcement outside the school.

That parent wasn't arrested, he said.

"That's a very dangerous situation," Mack said. "In this type situation, the only people that need to be armed are law enforcement."

Anthony Sampson, director of safety, security and attendance for Baldwin schools, said the Elberta Elementary School staff followed lockdown procedures precisely as they had been trained, and he hasn't heard any complaints or concerns from parents in the aftermath.

He confirmed that the school doesn't have a dedicated security officer, but does get regular visits from a deputy in the area. And while the incident might have been addressed more quickly had there been a resource officer on scene, "At the end of the day, the teachers acted accordingly and did what they needed to do."

Baldwin EMA Director Mitchell Sims lauded Elberta's teachers, as well.

"A lot of the teachers were proactive enough to say, 'Hey look, the police are here practicing today,'" Sims said. "That's the value of those teachers in those rooms, being smart on their feet and keeping those kids calm."

On Thursday night, Baldwin County schools Superintendent Robbie Owen expressed "tremendous appreciation" for the first responders, who he said were on scene within four minutes of the initial call of "shots fired."

"It was an amazing sight to see as they responded so quickly to our aid," Owen said.
