Hundreds have gathered in Cincinnati to remember the three people killed and the two injured in a downtown office shooting this week.

Many left bouquets of flowers alongside a fountain that sits at the center of Cincinnati's Fountain Square, just steps from where Thursday's shooting took place.

Cincinnati Mayor John Cranley says the first responders and the police officers who confronted and killed the gunman showed true heroism and bravery.

He says the officers risked their lives by running into the line of fire.

Police say they don't know why 29-year-old Omar Enrique Santa Perez decided to open fire in the building.

A 64-year-old contractor, a 48-year old bank employee and a 25-year-old engineer who worked as a consultant for the bank died in the attack. Two remain in the hospital.

New security footage shows a gunman who killed three people in a downtown Cincinnati office high-rise firing randomly while carrying a briefcase with hundreds of rounds of ammunition.

The footage released Friday also shows the shooter walking quickly past a security turnstile Thursday morning just as he's shot and killed by a police officer outside the building.

He says the shooter's gun jammed at one point during the four-minute rampage.

Police say they don't know why 29-year-old Omar Enrique Santa Perez decided to open fire in the building. They say he never worked there and an apartment search hasn't turned up any answers so far. An aunt of his described him as "very quiet."

Richard Newcomer, a contractor who worked for Gilbane Building Company, was one of three killed. Company spokesman Wes Cotter described Newcomer as a great employee, and struggled to describe how grief-stricken his coworkers are.

A Cincinnati coroner says she recognized the youngest person killed during a downtown shooting that left four dead, including the gunman.

The Cincinnati Enquirer reports Dr. Lakshmi Sammarco had met 25-year-old Pruthvi Kandepi at a local Hindu temple. The two also shared the same hometown and language, Telugu.

Sammarco posted Thursday on Facebook, asking how officials will explain to his parents "they will never see their son again because of a senseless shooting in a foreign country."

The local Telugu Association of North America office said they plan to help Kandepi's father. He wants his son's body to be taken back to India.

The other two killed are 48-year-old Luis Calderon and 64-year-old Richard Newcomer.

Twenty-nine-year-old Omar Enrique Santa Perez began shooting at a Cincinnati high-rise Thursday before officers opened fire on him.
