The deputy, an unidentified woman, was alert and conscious after the shooting and released from the hospital early Friday morning, officials said. The other victim, a man, remained hospitalized in stable condition.
Deputies said Laghaoui was wanted on multiple charges. He lives at the address where the domestic incident initially took place.
A shelter-in-place order was issued for residents as the manhunt continued. It left many people stranded for hours at area restaurants and businesses. Roads surrounding the search area were blocked to traffic.
More than 50 police cruisers, several K-9s and helicopters scoured the area, searching for any sign of Laghaoui. An Ohio State Highway Patrol helicopter equipped with infrared technology, or night vision, was also deployed, according to WCPO.
