An off-duty IMPD officer who fatally struck a pedestrian last week was under the legal limit at the time of the crash, according to a source close to the investigation.
The collision was reported just before midnight on Southport Road last Thursday.
A 911 call was made reporting a man walking in the middle of Southport Road near Emerson Avenue.
Then Zavalza, in a marked IMPD car, hit the pedestrian, identified Friday as 53-year-old Ronny Bowling, killing him. The officer stayed at the scene.
An IMPD supervisor said they noticed a smell of alcohol on Zavalza's breath.
He was taken to Eskenazi Health for blood tests.
Zavalza was placed on administrative leave, and his police powers were immediately suspended.
As of Monday afternoon, IMPD had not released the results of Zavalza's blood work.
Under Indiana law, a person may be charged with drunk driving with a BAC as low as .05 percent if other indications of impairment are present.
Police were reportedly still determining what, if any, charges might be filed.
