A 43-year-old Cumming woman is behind bars after authorities say she spiked her Waffle House co-worker's drink with methamphetamine.

Sonserea Dawn Evans has been charged with possession of a controlled substance with intent to distribute and aggravated battery. Both charges are felonies, according to authorities.

Dawson County Sheriff's spokesman Capt. Tony Wooten said authorities were called to the Ga. 53 East restaurant Dec. 23, just before midnight, after a call was received that a 37-year-old male employee was having a medical emergency.

The victim was rushed to an area hospital in serious condition, according to Wooten.

"He is still under medical care is my understanding. It is also my understanding that at one point he was in a comatose state and required a feeding tube and ventilator," Wooten said.

Authorities say that following the victim's hospitalization, law enforcement was notified that a video existed that showed the victim's drink had been drugged.

Waffle House management turned the video over to law enforcement.

"The video appeared to show Evans take her co-worker's drink toward the bathroom area of the restaurant when he went outside, then shows her returning it and him drinking it," Wooten said.

Evans' motives are unknown at this time, according to Wooten, as she is being uncooperative with the investigation.

Wooten said additional charges are possible, pending the victim's recovery.
