"My husband, he shot the police officers," the woman says in the recording, referring to the suspect, Quentin Smith.
Quentin Smith, 30, was arrested on Saturday after the shootings of Eric Joering, 39, and Anthony Morelli, 54, in Westerville, a suburb of Columbus, said Christa Dickey, the spokeswoman for Westerville's police department.
Joering and Morelli were responding to a domestic disturbance call when they were shot.
President Donald Trump on Sunday again offered prayers for the two officers.
It was the second time that the president had tweeted about the shootings.
Excluding the shootings in Ohio on Saturday, 12 U.S. law enforcement officers have been killed in the line of duty this year, nine in firearms-related incidents, according to the non-profit National Law Enforcement Officers Memorial Fund.
