Police investigate whether officer intoxicated

LOUISVILLE, Ky. - Louisville police are investigating whether an off-duty detective who shot an unarmed man this week was under the influence of alcohol at the time.

Police Chief Steve Conrad says investigators are primarily looking at the use of force in the case but that concerns were raised that the detective, Chauncey Carthan of the Narcotics/Intelligence Division, may have been under the influence when the shooting happened Tuesday night. Conrad said evidence was collected and submitted to the Kentucky State Police lab for analysis.

Carthan was in an unmarked car and in plain clothes at the time of the shooting. Police have not said what prompted him to shoot, and Conrad said he doesn't know many details yet.

Conrad said the man who was wounded was treated at a local hospital and released.

No charges have been filed. Carthan, who has been an officer in Louisville since 2001, is on paid administrative leave pending the investigation.
