A Waffle House waitress in Georgia is accused of spiking her co-worker's drink with methamphetamine, an act that authorities said left a 37-year-old man comatose.

“At one point,” Dawson County Sheriff’s Office Capt. Tony Wooten said, “[the co-worker] required a feeding tube and ventilator.”

Authorities were called to the Waffle House on Hwy. 53 about midnight Dec. 23 after learning the man was having a medical emergency.

They soon learned a video existed that showed a woman take the man’s drink toward the bathroom when he went outside, Wooten said.

“The video” he said, “… shows her returning it and him drinking it.”

The man, who was taken to a local hospital in serious condition, “is still under medical care,” Wooten said Wednesday.

Waffle House management gave the video to authorities.

The woman in the video "was immediately terminated," Waffle House spokesman Pat Warner told The Atlanta Journal-Constitution.

Sonserea Dawn Evans, the Waffle House waitress, was arrested on charges of possession of a controlled substance with intent to distribute and aggravated battery. It is not clear why she allegedly spiked her co-worker’s drink. Evans, 43, of Cumming, is not cooperating with investigators, Wooten said.

She is in the Dawson County Detention Center. Bond had not been set as of Wednesday morning.

Warner said Waffle House was cooperating with the authorities in their investigation.

“Our main focus,” he said, “is for our associate who is still in the hospital.”
