COVINGTON, Ky. -- A Cincinnati man died while Covington police officers tried to arrest him Tuesday morning.
Kentucky State Police is handling the investigation.
Officers made a traffic stop on Robert Ennis, 29, near the Latonia Kroger at about 6 a.m., Trooper Charles Loudermilk said.
Officials haven't yet said why Ennis was pulled over. Three other people were in the car with him.
He suffered a "medical emergency" at some point during the encounter with officers, Loudermilk said. He was pronounced dead at the scene.
"Whether it be something he did or a health emergency, officers began to give him first aid after they got him subdued," Loudermilk said.
Loudermilk said a gun wasn't used during the arrest. Still, he said investigators would "go through the same process as an officer-involved shooting," step by step, to determine what happened. That includes talking to witnesses, asking businesses for surveillance footage, reviewing body-worn camera footage and interviewing the officers involved.
An autopsy is scheduled for Wednesday in Frankfort, Loudermilk said.
