CORDELE, Ga. (AP) -- Two women have been arrested as part of the investigation into the weekend death of Alamo Police Officer Dylan Harrison.
Natalie Ammons, a spokeswoman for the Georgia Bureau of Investigation, said Charlotte Ferguson, 45, and Asia Kinsey, 24, were arrested Tuesday, WMAZ-TV reported.
Ferguson is the sister of Damien Ferguson, 43, who was arrested on a murder charge in Harrison's shooting on Sunday outside the Alamo Police Department.
The GBI said Charlotte Ferguson faces charges in Crisp County of hindering the apprehension or punishment of a criminal.
Kinsey was arrested on a charge of terroristic threats and acts for what authorities called a threatening social media post made relating to the investigation. She's being held in the Treutlen County jail.
It was unknown if either of the women had attorneys who could speak on their behalf.
Damien Ferguson was also charged Wednesday with bias-motivated intimidation of first responders related to Harrison's death.
Authorities said Harrison approached a driver Friday in the parking lot of a Circle K convenience store across from the police department after he observed a traffic violation. The driver refused to identify himself and the interaction escalated when the man pushed Harrison.
Harrison used his stun gun, arrested the man and took him to jail, authorities said.
"It is believed that the ambush-style attack on Officer Harrison was retaliation for the incident and arrest of the man," the bureau said in a statement on Sunday evening. They did not identify the man.
Harrison is survived by his wife and their 6-month-old son.
