A coroner in Cincinnati named the three men from 25 to 64 years old who died during Thursday's bank robbery, which also wounded two other people.
The Hamilton County coroner's office has identified the victims as Pruthvi Kandepi, 25, Luis Calderón, 48, and Richard Newcomer, 64.
The three were killed when police said Omar Enrique Santa Perez, 29, opened fire on the 30-story headquarters of Fifth Third Bancorp in downtown Cincinnati.
Two other people, a man and a woman, were wounded in the shooting before police officers arrived on the scene three minutes later and killed Perez.

The coroner, Dr. Lakshmi Sammarco, said he recognized the youngest victim, Kandepi, from a local Hindu temple. The two also shared the same hometown and the same language, Telugu.
Sammarco posted on Facebook on Wednesday, asking how officials will explain to their parents in India & # 39; that they will never see their son again due to a senseless shootout in a foreign country. & # 39;

The local office of the Telugu Association of America said they plan to help Kandepi's father. He wants his son's body to be taken back to India.
Cincinnati Enquirer reported that Kandepi worked as a programmer at a company called Tech Services.
Richard Newcomer worked for the Gilbane Building Company, based in Rhode Island.
On Thursday, the father and grandfather of Amelia, 64, was the supervisor of an electrical project on the third floor of the bank when he was shot to death.
According to the description of a GoFundMe page, Luis Calderón was a married father of two children, a boy and a girl.
The investigators said Perez, who wears suits, used a 9-mm gun and had approximately 200 rounds or more of ammunition. So far, they have not found a reason.
Police Chief Eliot Isaac said investigators will study images of officers' body cameras and the safety of the 30-story building.
According to the police, Perez had never worked at Fifth Third and does not have any information linking him to other companies in the building.
Authorities believe Perez had lived in the Cincinnati area since 2015. Police invaded his apartment in North Bend, Ohio, about 15 miles away.

Records show that the shooter previously lived in South Florida and had been accused of nonviolent crimes for years.
Police said they entered a sandwich shop and possibly other companies before entering the lobby and opening fire around 9.10am.
Hamilton County prosecutor Joe Deters said the swift police response likely prevented many more victims. He said an investigator said it could have been "a bloodbath beyond imagination."
Leonard Cain told the Cincinnati Enquirer that he would go to the bank when someone alerted him about the shooting. He said a woman with hearing aids did not listen to the warnings and went into the bank and was shot.

The two wounded, a man and a woman, were included there in critical condition and in fair condition, respectively.
The Inquirer identified the survivor as Whitney Austin of Louisville, Kentucky, 37 years old.
The mother of two children, married, received 12 bullet wounds on one side of the body, but the bullets missed all of her vital organs and arteries, Austin's neighbor told 9News.
Her brother-in-law Lonnie Gardner told the Courier Journal that she was aware and called her 12-year-old husband, Waller Austin, from the ambulance on the way to the hospital.
Fountain Square is often the site of concerts, dances, food trucks and other events at lunchtime or at night.
"It could have been any of us," said Mayor John Cranley. He praised the police and other emergency personnel and said: "It could have been much, much worse."
