Patterson was later arrested behind an apartment complex in Cobb County.

Channel 2′s Larry Spruill spoke to a woman who said she had a hunch and suggested to police that they search a poolhouse at her apartment complex.

“(It had) a shower area with no windows or anything,” she said. “It was just the perfect place to hide.”'

She said that officers swarmed the area moments after she gave them a tip.

Channel 2′s Sophia Choi spoke to Patterson’s parents off-camera after the shooting. His mother said he became agitated when doctors would not give him Ativan, an anti-anxiety medication.

Police said he opened fire in a waiting room before leaving the scene about two minutes later and running to a nearby Shell station, where he stole a white Toyota Tacoma truck.

The truck was found a few hours later in a parking garage near the Battery.

NewsChopper 2 was over the highway Wednesday night as officers escorted Patterson back to Fulton County.

Police have not identified the survivors, except that they ranged in age from 25 to 61.

The U.S. Centers for Disease Control and Prevention later confirmed that St. Pierre, the victim who was killed, was a CDC employee and offered condolences to her loved ones.

Patterson now faces four aggravated assault charges and a single charge of murder.
