Police were on the scene within six minutes, but Grady said they found no trace of the suspect or vehicle until hours later when a deputy heard popping noises in the distance around 4:30 a.m. and the agency went into active-shooter mode, bringing all state and local law enforcement in the area to the scene.
When they arrived, breakable lights lined the driveway to the home. They saw a truck — believed to be the suspect's — on fire and heard more gunshots.
The suspect was also there, heavily outfitted in body armor "as if he was ready to engage us all in an active shooter situation," Judd said, but noting they didn't see a weapon.
The suspect immediately ran back into the home, where authorities heard another round of gunfire, "a woman scream and a baby whimper."
Officers tried to enter the front of the house, but it was barricaded. When they circled to the back, they encountered the shooter and exchanged heavy gunfire, before the suspect retreated back into the home.
Everything fell silent, Judd said, except for the helicopter blades overhead, until the suspect came out to surrender. He had been shot once.
Authorities moved in and found an 11-year-old girl who had been shot multiple times. She told deputies there were three dead people inside, Judd said.
Deputies sent robots into the home to check for explosives and other traps. When it was clear, they found a mother with an infant in her arms, and another unidentified victim all dead from gunshot wounds. They also found another woman fatally shot in a neighboring home.
