Cincinnati shooting's death toll could have been higher, authorities say

Emergency personnel and police responded to a reported shooter near Fountain Square in Cincinnati Ohio

The suspect, Omar Enrique Santa Perez, had a pistol and more than 200 rounds of ammunition, police said.

The shooting was "clearly an act of grotesque violence", and should "frighten all", said Cincinnati Mayor John Cranley.

The Cincinnati Enquirer reported that with four dead, including the gunman, this is the deadliest mass shooting in the Cincinnati region since 2013.

The motive of the shooter, whose identity has not been released, was not known.

"She walked in the door and he shot her", Cain told The Cincinnati Enquirer, adding that he heard up to 15 shots fired. "He was actively shooting innocent victims", the mayor added.

Authorities said the death toll in a gunman's attack on a downtown Cincinnati office building could have been higher.

He was not a current or former employee at the center, whose primary tenant is the Fifth Third Bank headquarters, and officials say they are not sure of his connection with any surrounding businesses.

The chief says they had a "quick response" and 'there is no additional threat'.

Austin is grateful for the officers who aided her and for the support from many others, the spokesperson said.

The chaos unfolded alongside Fountain Square, the heavily trafficked park at the city's center.

The victims have been identified as Pruthvi Raj Kandepi, Richard Newcomer and Luis Felipe Calderón, according to the Hamilton County Coroner. Two other victims are being treated at University of Cincinnati hospital.

Ebony Ginyard, who works at a Dunkin' Donuts in Fountain Square, said she and other workers and customers dropped to the floor when the shooting erupted, according to Reuters. "After that, I started running", Richardson said. Isaac said the gunman then entered the bank's lobby where he exchanged gunfire with police.

"This is a horrific incident", Isaac said.
