A man was arrested Sunday after he fatally shot his 27-year-old ex-girlfriend and stabbed a police dog during a manhunt, authorities said.

Randy Bernard Young, 31, was taken into custody about five hours after he ran from the shooting at a Clayton County apartment complex, Channel 2 Action News reported.

The woman was identified Monday by police as Amber Wilson, a detention officer in Irwin County.

About 9:30 a.m., officers went into a unit at the Brookstone Apartments on Garden Walk Boulevard in College Park, Clayton County police Sgt. Ashanti Marbury said.

They found an unresponsive woman who had been shot multiple times. Clayton County Fire and Emergency Services responded and said she was dead, according to Marbury.

“The preliminary investigation revealed that the shooting was domestic in nature,” she said. “The female victim traveled to the location accompanied by a family member with the intention of retrieving her personal items from the apartment.

“Prior to arriving at the location, it is known that she was involved in a verbal altercation with the suspect over the couple breaking up and her decision to move out of the residence.”

According to the family member, after arriving at the location, they were confronted by the man, who was  brandishing a handgun, police said. He fired shots.

The slain woman’s family member escaped, and Young reportedly took off running.

He was later located in a wooded area in Riverdale, according to police. During the manhunt, a Clayton County police dog was deployed and was stabbed twice by the man.

“It's just a horrible incident, of course,” Maj. Tina Daniel told Channel 2. “Our K-9s are considered family. They protect our officers and stand by our side during incidents like this.”

The dog was taken to an animal hospital and was recovering from surgery Monday.
