Police searched the home of Craig Stephen Hicks, 46, after charging him with three counts of first degree murder in the shooting deaths of Deah Shaddy Barakat, 23; his wife Yusor Mohammad Abu-Salha, 21; and her sister Razan Mohammad Abu-Salha.
The three were found dead Tuesday evening at the home of the newlywed couple.
Hicks surrendered himself to police early Wednesday morning and was charged.
Police executed search warrants at Hicks home on the night of the shootings and found two fully loaded handguns, a fully loaded AR-15 Bushmaster rifle, two shotguns, five other rifles, two other handguns and two pellet guns. Warrants also say investigators seized a number of magazines with varying amounts of ammunition, boxes of ammunition, shotgun shells, BBs, gun scopes and other items.
Two computers, three cell phones and a digital camera were also seized.
Hicks described himself in online posts as a "gun-toting atheist." He also described himself as an anti-theist.
According to the search warrants, a woman flagged down police and directed them to Barakat's and Yusor Abu-Salha's condo, saying her friend was bleeding. When officers arrived, they found Barakat dead in the front doorway bleeding from the head; one of the sisters was found in the kitchen and the other was in the doorway to the kitchen.
The warrant also says a witness outside told police that he heard shots and saw a man leaving the condo and driving off in a gold car.
A second warrant said police found eight shell casings in the living room of the condo and a bullet somewhere inside. Police also seized three cellphones, a watch, two sets of keys and Barakat's wallet and keychain.
Hicks surrendered to law enforcement in Pittsboro. A third warrant shows investigators swabbed the driver's door handle and steering wheel of his Nissan for evidence and seized his vehicle registration and insurance card.
Investigators met Friday morning with FBI agents and federal and Durham County prosecutors to discuss the case. The FBI opened an inquiry into the shootings on Thursday.
