CINCINNATI, OH (FOX19) - Hamilton County Coroner Dr. Lakshmi Sammarco released new details Tuesday about the fatal shootings at Fifth Third Center Downtown.
Gunman Omar Enrique Santa Perez, 29, opened fire inside the bank's national headquarters on Fountain Square just after 9 a.m. Thursday, killing a Fifth Third Bank employee and two contractors and wounding two others.
Sammarco said of the three victims that died, one was shot once, a second was shot seven times and another victim suffered from four gunshot wounds.
"It was a mix of ammunition – he had one gun and a couple of different types of ammunition," she said.
According to Sammarco, Santa Perez was killed by shotgun wound to the head. He also had several other wounds.
"We are aware two other people were shot and we're grateful they're still alive. He was walking very determinedly, with his head high, his back straight... there was no hesitation in what he did," she said.
Sammarco has said she met with one of the victims, Prudhvi Kandepi, 25, at a local Hindu temple.
They also shared the same Indian hometown and heritage.
Sammarco has identified the other victims who died as 48-year-old Luis Calderon and 64-year-old Richard Newcomer, who will be laid to rest Tuesday. His funeral will be 10 a.m. at St. Veronica Church, 4473 Mt. Carmel Tobasco Rd.
One of the two surviving shooting victims, Whitney Austin, was hit 12 times.
The Fifth Third vice president is recovering at University of Cincinnati Medical Center. She is listed in fair condition.
Her husband wrote in a Facebook post Monday her survival is a "miracle."
The other surviving shooting victim, Brian Sarver, was released from the hospital Monday night.
Cincinnati police responded within minutes of the first shot being fired and killed Perez in the lobby of the high-rise.
Sammarco added her office doesn't see cases like this and gave condolences to the families.
"This is Cincinnati, Ohio. We don't have mass shooting here. We don't see cases like this," she said. "We're truly sorry for what they're going through and I never would've imagined that'd happen here in Cincinnati."
Cincinnati police have said Perez used a 9 mm handgun he legally bought about a month ago on the West Side and had more than 200 rounds of ammunition.
It remains unclear why he opened fire.
Cincinnati Police Chief Eliot Isaac has said the gunman's mental health history is one of several areas they are investigating.
