John Michael Taylor, 27, of Acworth, was arrested after holing up in a house near Dawsonville for about three hours.
Krystle Gail Taylor, 27, of Dawsonville was arrested there earlier.
SWAT teams from Cherokee and Forsyth counties and Dawson County sheriff’s deputies were involved in the standoff.
After negotiating with John Michael Taylor for several hours, SWAT team officers were able to get in through the front door and use a taser on the suspect, Garrison said.
“Two out of the three are now in custody,” Garrison said.
Cherokee County detectives issued arrest warrants Tuesday in the murder of Christopher Pierce, who was found shot to death in his Woodstock home on Sunday.
Investigators said the Taylors, along with Benson Kyle Lloyd, 28, of Jasper, were wanted in the death of Pierce. The three were considered armed and dangerous. Fox 5 reported they are suspected drug dealers with connections in Cherokee, Pickens, Cobb and Catoosa counties.
Pierce was found in his home on the 100 block of Misty Hollow Way around 5:15 p.m. Sunday by his father, Frank Pierce, who owns the house.
Lt. Col. Ron Hunton, field operations commander for the Sheriff's Office, said investigators believe that there was no apparent forced entry to the home and that Pierce knew the suspects.
Frank Pierce said Tuesday he had never heard of the suspects accused in his son’s death, but he was glad detectives had identified them.
