CAMDEN, Ark. (AP) — The Arkansas man accused of killing four people and injuring 10 others, including two police officers, in a mass shooting at a grocery store pleaded not guilty Tuesday to multiple charges connected to the attack.

Appearing in court for the first time, Travis Eugene Posey, 44, pleaded not guilty to four counts of capital murder and ten counts of attempted capital murder for a shooting last week at the Mad Butcher grocery store, the Arkansas Democrat-Gazette reported. A judge ordered Posey held without bond.

Police have not identified a motive for Posey, 44, who was shot and injured by officers who exchanged fire with him. Police have said he did not appear to have a personal connection to any of the victims. Gregg Parrish, the executive director of the Arkansas Public Defender Commission, represented Posey at the brief hearing. Parrish did not immediately respond to a message from The Associated Press late Tuesday afternoon.

Posey spoke briefly at the hearing to say Parrish had explained the charges to him, the Democrat-Gazette reported.

Posey on Friday carried a 12-gauge shotgun, a pistol and a bandolier with dozens of extra shotgun rounds, authorities said. He fired most, if not all, of the rounds using the shotgun, opening fire at people in the parking lot before entering the store and firing “indiscriminately” at customers and employees, police said.

It was at least the third mass shooting at a U.S. grocery in the last three years. In 2022, a white supremacist killed 10 Black people at a Buffalo supermarket. That came a little more than a year after 10 people were fatally shot at supermarket in Boulder, Colorado.

Authorities have said Posey had limited to no criminal history, though he was arrested in 2011 at the entrance of Fort Drum in New York and charged with misdemeanor criminal possession of a weapon. Posey said he was a truck driver attempting to make a delivery when he voluntarily told police at the gate he had an unloaded pistol, according to New York State Police. Posey ultimately pleaded guilty to disorderly conduct and paid a $200 fine.
