The four Cincinnati Police officers who shot and killed the Fifth Third Center shooter had previously received numerous commendations during their years of service.

Police previously identified the four who responded to the scene first as Officers Jennifer Chilton, Antonio Etter and Eric Kaminsky along with police Specialist Gregory Toyeas. They responded "within seconds" of the shooting, Chief Eliot Isaac has said.

The shooter, Omar Santa Perez, 29, was killed at the scene by the responding officers.

Richard Newcomer, 64, Prudhvi Raj Kandepi, 25, and Luis Calderon, 48, were killed in the attack. Severely injured were Whitney Austin, 37, and Brian Sarver, 45.

The personnel files of each of the four officers first on the scene were released by the CPD Thursday in addition to several other records. An Enquirer review of their files shows a range of experience and dozens of commendations between the four officers.

Here's what we learned from their files:

Specialist Gregory J. Toyeas

On Sept. 6 Specialist Gregory J. Toyeas ran past the shooter and then engaged him with his firearm, forcing the shooter to run toward the other officers on scene.

Toyeas has been with Cincinnati Police since 1990 and has worked in many areas, including District 4, the SWAT and Tactical Unit and Central Business Section.

Toyeas has worked with the aviation unit to teach others and has been an instructor with the police academy.

In 2015 he received commendation from the Cleveland Browns for helping with transportation. He often receives praise from motorists.

“If every CPD officers is as professional, amicable and courteous (as Toyeas) then the CPD has the best force in the nation,” wrote someone in a commendation in 2005.

Officer Jennifer M. Chilton

Officer Jennifer Chilton began at the police department in 2008. She has mostly worked at District 1 and District 2 and has worked in the Vice Unit. She is currently a District 1 neighborhood liaison, a position she has had since 2015.

In her annual review, a supervisor said she is “regularly thanked by community members for her quick response to questions and concerns.”

For three years, she has met or exceeded standards.

“Officer Chilton’s positive attitude and pleasant disposition is a character trait that weighs heavy with customer service and her ability to work with our communities and those that serve with her,” wrote Sgt. Hank Ward, neighborhood liaison sergeant.

Chilton, whose focus is on Mount Adams, has received praise from the Mount Adams Civic Association for response to homeless encampments in the past.

On Sept. 6, she engaged the shooter with her firearm with the first team on the scene.

She is a graduate of Mariemont High School, according to her file.

Officer Antonio D. Etter

Officer Antonio D. Etter began with the department in 2002 and has worked in District 5 since 2006, where he has also worked on the violent crime squad.

Etter was working a nearby off-duty detail on the day of the shooting. He left his detail and engaged the shooter with his firearm. Police and coroner's investigators believe Etter fired the shot that stopped the Sept. 6 shooter.

Etter was described as a “reliable beat officer” who is “always ready and willing to work with other officers to get the job done.”

Two supervisors have recommended that Etter study for a promotion to sergeant, according to his file.

In 2011 he received praise from then-Police Chief James Craig for “dedication to duty, professionalism and teamwork which resulted in a significant apprehension.”

He graduated from Aiken High School and took classes at the University of Cincinnati.

Officer Eric A. Kaminsky

Officer Eric A. Kaminsky was recruited in 1997 and has been at District 1 since 2009. Kaminsky was described as a model employee and has worked with many motorists during his time at the department.

“Officer Kaminsky’s strongest asset is his ability to care so deeply about everything he touches,” a supervisor wrote.

On Sept. 6, he engaged the shooter with his firearm with the first team on the scene.

Kaminsky has received more than 40 commendations for kindness and going above the call of duty. Supervisors said he “goes out of his way to help the citizens of our community.”

Kaminsky graduated from Anderson High School and served in the U.S. Navy for five years prior to becoming a police officer.

Records: 63 officers responded to the shooting

Dispatch logs from the Sept. 6 mass shooting at the Fifth Third Center show 63 officers responded to the scene of the shooting.

The logs, which were released by the Cincinnati Police Department on Thursday along with 911 calls, radio traffic and other records, indicate that FBI agents also assisted first responders at the scene of the shooting.

The records, the footage and other documentation were released after The Enquirer pursued legal action against the City of Cincinnati.

The Enquirer will update this story as more records, calls and videos are reviewed.
