The parents of an environmental activist who Georgia state troopers fatally shot near the site of a planned Atlanta-area police and firefighter training center filed a lawsuit Tuesday against three law enforcement officers who they say planned and carried out a police raid that led to his death.

Manuel Paez Terán’s family says state troopers used excessive force against the 26-year-old when they fired pepper balls into the protester’s tent after Paez Terán refused to leave on the morning of Jan. 18, 2023. Authorities said Paez Terán then shot at the troopers from inside the tent, wounding one of them and prompting the troopers to return fire, killing the activist.
