Suspect taken into custody without incident, technology 'played a huge role': Police
The suspect was taken into custody without incident, police said Wednesday during a press conference.
The suspect entered the medical facility shortly before noon and allegedly shot the first victim shortly after, Deputy Chief Charles Hampton said. The suspect spent two minutes in the building before exiting and going to a Shell gas station, where he commandeered a pickup truck, according to Hampton.
Officers were able to place the license plate number into the reader system, Hampton said, and received an alert at approximately 12:30 that the suspect was in Cobb County.
Technology "played a huge role," Cobb County Police Chief Stuart VanHoozer said, "but technology doesn't work without the dedicated people behind it."
Police had checked and cleared an unoccupied building they knew the suspect had gone into, VanHoozer said, adding that a "real-time operator" took a 911 call and had an instinct that it was legitimate, and they prioritized that call.
An undercover officer made the first contact with the suspect and had backup from uniformed officers, the chief said.

Suspect seen in Cobb County shortly after shooting, police say
Police in Cobb County said Deion Patterson was seen on video in the county around 12:30 p.m. ET, roughly 20 minutes after the shooting, though it's unclear if he's still in the area.
Cobb County Police Sgt. Wayne Delk said during a press briefing that after learning Patterson might be in the area, his team checked flock cameras and "did discover that the vehicle had entered Cobb County," located northwest of Midtown Atlanta, where the shooting occurred.
"Around 12:30 p.m., we did spot what appeared to be a suspect in this area, which is why we have such a heavy presence," Delk said.
Police did not discover the video footage until around 2:30 p.m., and Delk acknowledged it's unclear if Patterson is still in the county.
"He might still be in the area," he said.
The vehicle Patterson was believed to be driving was recovered by Atlanta police in a parking garage, Delk said.

Slain CDC worker remembered as 'brilliant, kind, big-hearted'
The family of 39-year-old Amy St. Pierre is speaking out about their profound loss.
"Our beloved Amy was brilliant, kind, big-hearted and simply the 'best of the best,'" her family said in a statement. "Loving wife and mother of two, middle sister to two brothers, and cherished daughter, she was truly our pride and joy."
St. Pierre worked at the Centers for Disease Control and Prevention's Division of Reproductive Health, according to CDC Director Dr. Rochelle Walensky.
"An Emory honors graduate and Georgia State MBA, Amy traveled the world with curiosity and courage," her family said. "She was driven by compassion, both in her work in the field of maternal mortality, and in her everyday life. Amy was selfless always, she wanted more for others but never for herself. Generous supporter of worthy causes, she was the social conscience of our family."
